Brittany Johnson, Hiring Manager Chipton-Ross 47806 Gertrude Way La Quinta, California 92253

Dear Ms. Johnson:

Keen foresight, enthusiasm for inventing creative solutions, and an engineering background keep me happily fixing bugs and optimizing software throughout the entire development life cycle. This is an opportunity for us to partner together, where I’ll apply my proficiency in C#, LabVIEW, Linux, Vector Cast, and more toward achieving Chipton-Ross’ goals of collaboratively providing superior services to the staffing industry.

The last 7 years with Embark’s development team have seen me strategically apply knowledge of C# and oversee the implementation of cross-functional advertising software that improved page loading speed by 17 percent. Scaling to over 34 million users, this software application simultaneously boosted company profits and customer satisfaction rates.

I also fused my familiarity with SignalR and JavaScript framework with my drive to problem-solve and streamline existing company software. Leveraging my proficiency in these tools, I helped my team develop a unit testing infrastructure that eliminated bugs within the application. My proactivity spoke for itself in the structure’s engineering when we saw a 61-percent reduction in client-reported bugs over a 6-month period.

The strong team culture at Chipton-Ross resonates with me as I enjoy thinking analytically to resolve questions of program intent and translate documentation and data into helpful operating instructions for my coworkers. I welcome further discussion, so please contact me for details on how my software engineering experience will benefit your team and maximize client savings.

Thank you for your time and consideration,

Jerry Manilla

November 20, 2023

Abigail Clark Northrop Grumman Corporation 123 Fictional Lane Baltimore, MD 21201

Dear Ms. Clark:

Intrigued to the core by Northrop Grumman’s relentless pursuit of solutions for space, aeronautics, defense, and cyberspace challenges, I can’t help but jump at the opportunity to serve as a software engineer intern. The chance to immerse myself in the endeavor of crafting software capable of meeting the nuanced demands of clients across the globe aligns not just with my career aspirations but also feeds my insatiable appetite for learning from leaders who triumph over the most challenging technological terrains.

In my software development course at Loyola University Maryland, I channeled the raw power of Python, creating a novel application designed to streamline problem-solving. As validated by user trials, this application manifested into a potent tool capable of boosting productivity by 18.6%. This achievement was driven by an unwavering dedication to clean, efficient code, a feat made possible by my systematic implementation of Git. The version control system served a two-fold purpose: ensuring a pristine codebase and facilitating a well-oiled project workflow.

Following my academic expedition, I eagerly plunged into the cutthroat world of cybersecurity at the Maryland Cyber Challenge. My team and I designed a digital fortress with Python-built security protocols to repel data breaches. In an ingenious move, we automated primary functions that helped us identify, neutralize, and deflect 73.2% of simulated cyber-attacks.

Earlier this year, I interned at a thriving Baltimore startup, Esurgi. Here, I had the opportunity to work on a database management project, wielding the power of PostgreSQL. Rebuilding and redesigning database schemas introduced refreshing modifications that catalyzed a tangible 21.4% acceleration in data retrieval speeds.

The prospect of joining the Northrop Grumman team and applying hands-on experience from academic coursework and competitions to real-world challenges is thrilling. With heartfelt appreciation, I look forward to perhaps harnessing this opportunity to learn, grow, and contribute to the trailblazing mission that your organization undertakes.

• For example, Amara’s stint as an intern at Esurgi shows her using PostgreSQL for database management, providing the recruiter with tangible evidence of her competency even as an intern. How you weave in this tale matters, though. Outline your responsibility and impact catalyzed by your contribution. Top it off with the lessons learned.

Daniel Thompson Medtronic 123 Fictional Lane Memphis, TN 38101

Dear Mr. Thompson:

In response to Medtronic’s quest for pros who understand the power and potential of software in transforming healthcare, I’m compelled to apply my abilities in programming languages, version control systems, and more as an entry-level software engineer. The opportunity to contribute to meaningful applications that positively impact health resonates deeply and aligns with my personal and professional aspirations.

My computer science coursework at the University of Memphis cultivated a solid mastery of Java, a language well-suited to building large, enterprise-level applications. Also, my fluency in Python has been instrumental in data analysis and scripting—crucial skills in developing and maintaining healthcare software.

Interning at MiCare Path, I gained valuable experience in version control systems. I played a crucial role in administering the Git system, smoothing the development workflow and reducing code conflicts by an estimated 16.7%. This opportunity deepened my understanding of collaboration in software development while improving code quality and project management.

Additionally, I embarked on an independent project to develop a dynamic website from scratch. I used HTML, CSS, and JavaScript to create an intuitive user interface and functionality. This health-based information platform has witnessed about 142 new users within its first month, demonstrating effective use of web development skills to provide valuable resources to the public.

Combining academic, professional, and independent project experiences, I believe my versatile skills and strong problem-solving ability align with Medtronic’s mission to ease pain, restore health, and prolong life. I look forward to discussing how my skills can contribute to Medtronic’s innovative solutions. Thank you.

Gabriel Santos

• Take, for instance, that journey of using HTML, CSS, or JavaScript to build a website from scratch. Let your enthusiasm show as you describe the project’s purpose and wins, such as garnering 142 new users within the first month.

Robert McKenley, Hiring Manager Rushdown Studios 462 Chelsea Rd Oceanside, New York 11572

Dear Mr. McKenley,

As a Python software engineer with 5 years of experience alongside countless more as an avid gamer, I’m confident I would make a skilled and valuable addition to Rushdown’s team. Just as I live for each new gaming challenge in Twisted Treeline, I thrive in environments that challenge my strategic planning and creative use of skills such as PostgreSQL, AWS, and Docker.

As an adept problem-solver with a strong background in Oracle and RESTful APIs, I worked with my old team at Knewton to diagnose issues with current application infrastructures and eliminate errors to improve user feedback by 23 percent. I would say that RESTful APIs are my “ultimate ability.” I also used my deep familiarity with REST in a team setting to boost page loading speed by 16 percent.

Additionally, I have extensive experience adapting to a vast pre-existing codebase while helping my teammates pinpoint and prioritize obstacles; this resulted in optimized teamwork as well as optimized solutions. For example, I collaborated with my development team on a testing infrastructure with broad coverage that reduced bugs by 11 percent and cut down negative customer feedback on Knewton’s cooperative programming by 21 percent.

While I’m grateful for all I’ve learned in previous roles, I’m eager to apply my gaming passion and knack for problem-solving to excel as your Python software engineer. I’m excited to share with you at your earliest convenience how I intend to leverage my communicative, multitasking, and technical skills to set my crosshairs on each new obstacle and help level up Rushdown’s team—creating the ultimate gaming experience.

Thanks very much for your consideration,

Clive Russo, HR/Hiring Manager UCLA Health 4562 Larwin Ave Cypress, California 90630

Dear Mr. Russo:

The journey of a friend who won his battle with cancer came to mind as I read about your new Cancer Data Sciences group. I knew as a compassionate senior software engineer, I could use my skills to help others win their battles, too. I offer the advanced analytical thought patterns needed to create scalable software solutions, and I’m ready to optimize your local high-performance computer infrastructure along with your cloud-based assets. I can effectively analyze data and collaborate with a broad team of data scientists to streamline tools that UCLA Health can use to provide the best patient experiences.

After working with C++ and Oracle at Adaptiva to build cloud-based technologies that boosted productivity by over 43 percent, I expanded my focus to include engineer-client communications to smooth out collaboration and UI/UX further. My proficiency in data modeling, SQL, and AWS allowed me to analyze and integrate feedback for increasingly improved code quality.

My talent in engineering and developing large, highly responsive UX-personalization applications that can scale with rapidly growing datasets empowered me to engineer algorithmic software that responded and adapted to customers’ individualized needs based on personal history. This boosted sales by 19 percent, and I’m confident that this experience would translate seamlessly from improving customer experience to streamlining workflow for medical staff to care for patients more effectively.

The well-rounded experience I’ve gained in programming, design, and in-depth analysis makes me an ideal senior software engineer candidate for UCLA Health. I am eager to tackle any parallelization, containerization, or algorithmic design problem you send my way, and I think you’ll agree once we’ve had the chance to discuss the role further. I look forward to hearing from you soon.

Thank you for considering me to join your team,

Beverly Hanes

Write Your Best Software Engineer Cover Letter

All in all, the best cover letter will demonstrate a strong understanding and connection with the company. A software engineer can do this by using their technical skills to relate to the role in the job description coupled with the company’s overall vision and goals—all with a winning tone and positive message, of course!

Use the following steps to guide your writing process so you can write your best cover letter yet. 

Step 1: Know the company & understand the role

So many cover letters out there are snooze-fests that wind up in the recycling bin. To ensure yours isn’t one of them, pay attention to the details of the specific software engineer position you’re applying for and tailor your cover letter accordingly. 

Read the  software engineer job ad . Keep an eye out for things that set it apart—details like specific programming languages and software strategies, for example.

Research the company, too! Your software engineer cover letter must not only demonstrate a crystal-clear understanding of the role as laid out in the job description but prove that you’re a great fit with the company’s values, goals, and core missions. Just a handful of details showing that you know the company’s vision and software engineer role better than the average applicant will go a long way in setting you apart from other applicants. 

Step 2: Align your successes with the company’s needs

Your  software engineer resume  offers recruiters a quick peek at your skills and professional history. Since it’s less than a page, you don’t have much space within your bullet points to give a more extensive explanation of how your skills and experience make you an ideal candidate for the specific position. That’s the job of your cover letter! 

Touch upon the best points in your software engineer resume but expand upon them with descriptions of how you accomplished said achievements as well as the positive impact they had. Don’t just talk about what you created—talk about what it did to benefit others. 

• Taking this a step further, your resume might list your Python and MySQL skills—but how did you apply them during your last job?
• Did you build an application that boosted profit margins and kept them growing after you departed?
• Did you engineer an analytical or testing application that significantly reduced bug and error reports?
• Maybe you singlehandedly optimized an application to skyrocket customer satisfaction rates: If you did, say so! 

This is your opportunity to show off your greatest accomplishments anecdotally and tie them into what the job description requests. 

Tip 3: Don’t underestimate your tone & message

As you can probably imagine, there’s a lot more that goes into a cover letter for software engineers besides technical information. The overall message of your letter should mirror the qualities that the job listing calls for and demonstrate the values and vision of the company as a whole.  You don’t want to just convey that you’re a software engineer who can work wherever—your message needs to convey that you want to work  there!

As a software engineer with a vast array of technical skills and fascinating professional experiences, it might be tricky—but keep your cover letter to a page. And within that space, consider your tone of voice. 

Your tone should match the role: Senior software engineer candidates should convey confidence and experience, and all applicants (especially entry-level ones) should demonstrate enthusiasm and eagerness to contribute to the company.

Additionally, consider the company culture and vibes. Working for a healthcare company likely means you should take a bit more formal tone while employers at a gaming company will probably appreciate a little pizazz and a more conversational approach.  

Software engineer candidates should convey confidence, experience, and demonstrate eagerness to contribute to the company.

Lastly, set aside time for editing and revising. It may take several tries to get the message and tone of your cover letter just right, but the extra effort is worth it! Ensure you clean up embarrassing typos or copy-paste mishaps in your cover letter, and be deliberate about word choice to refine your tone. 

Start with Our Outline for Your Software Engineer Cover Letter

Outlining your software engineer cover letter is a great way to make sure you don’t forget any key points. And just as  formatting your resume  is important, format matters in your cover letter, too; we’ve got you covered. 

How to start a software engineer cover letter

Your contact info:  List your name, phone number, location, and email (if you’re using a templated cover letter). 

• Formatting:  Leave out your name here if you’re using a business block format for your address.

Date:  Use the exact date that you submit your application materials 

• Formatting:  Write out the full date instead of shortening it, e.g., January 5, 2023.

Inside address:  This is the recipient’s address. Include their name, company and position, and the company’s address.  

Clive Russo, Hiring Manager UCLA Health Human Resources 4562 Larwin Ave Cypress, California 90630

• Formatting:  Each part of the address should be on a new line. Remember to double-space between the inside address and your greeting, too. 

Greeting:  Your greeting/salutation is your crucial first impression! Do your homework and uncover the name of the hiring manager or employer, avoiding generic terms like “To whom it may concern,” and please, at all costs, never start with “Dear Sir or Madam.” Ick!

• Formatting:  Use a colon instead of a comma after your greeting for more formal companies. Companies like Rushdown (see the Python software engineer cover letter sample) are far more casual; a comma will do just fine.

How to write your software engineer cover letter

Body:  The body of your software engineer cover letter should be 3-4 paragraphs that demonstrate your interest, show off your credentials, and exhibit an appropriate level of enthusiasm for future discussion.

• Formatting:  Lines should be single-spaced throughout the body but double-spaced between paragraphs.

Opening paragraph:  Don’t be generic or vague. The last thing you want is for a potential employer to say “Boring!” and toss your cover letter aside.

Bad : I really like gaming, so it’d be great if I could work for your company. I’m familiar with plenty of technical tools that would help your company.

Why It’s Bad : Based on what we just discussed, this cover letter has already been tossed. It’s great that the applicant apparently loves gaming and has technical skills—but exactly how will they help the company . . .? What “technical tools” are they?

Good : As a Python software engineer with 5 years of experience alongside countless more as an avid gamer, I’m confident I would make a skilled and valuable addition to Rushdown’s team. Just as I live for each new gaming challenge in Twisted Treeline, I thrive in environments that challenge my strategic planning and creative use of skills such as PostgreSQL, AWS, and Docker.

Why It’s Good : This introductory paragraph dives into the applicant’s experience and demonstrates a strong personal connection with the company’s passion for gaming—all while exploring technical skills the job description specifically listed in its requirements section. Nice!

Paragraphs 2-3:  These paragraphs are for you to shine the spotlight on your best achievements that align with the job ad and with the company’s goals, values, and mission.

It’s time to put your money where your mouth is—but remember to maintain a clear focus in each paragraph. You don’t have room for all your awesome achievements, so try to stick with one major point per paragraph and include only the most relevant metrics and results.

Why It’s Good : Beverly highlights something from the job description that she’s already done (engineering large-scale algorithmic software) and provides the number as evidence of her claim. She also clarifies exactly how this accomplishment will benefit the place where she’s applying now, even though her past experiences were applied within a very different type of company.

Closing paragraph:  Finish strong with a concise but compelling statement of how your traits and abilities as a software engineer align with what the company or organization needs. And lastly, end with an enthusiastic call to action that encourages future contact with the company.

Bad : As you can see in my letter, I’m well qualified for this position and would do a great job with my skills. Call me anytime for more info and I can tell you more about the other stuff I can do.

Why It’s Bad : Where do we even start with this one? Your cover letter should be specific, adding more tidbits on why you’re an excellent fit whenever possible. This redundant first sentence and boring, informal call to action are inexcusable.

Good : The strong team culture at Chipton-Ross resonates with me as I enjoy thinking analytically to resolve questions of program intent and translating documentation and data into helpful operating instructions for my coworkers. I welcome further discussion, so please contact me for details on how my software engineering experience will benefit your team and maximize client savings.

Why It’s Good : This one works. You can see how the applicant’s traits and experience align with the company’s values, and there are several keywords that came straight from the job description. Additionally, the call to action is welcoming yet professional while reinforcing the candidate’s value to the company. 

How to end a software engineer cover letter

Signature:  Say “thank you” if you didn’t do that in your closing paragraph, and always use a professional close along with your real name.

• Formatting:  If you’re handing out hard copies of your software engineer cover letter (anyone out there still doing this?), quadruple-space before your name. This allows space to sign by hand in blue/black ink. 

Enclosure(s):  This part of your cover letter is important since it signals the recruiter to look over any supplemental materials. Pay attention to the job description for requested materials like certifications or letters of recommendation. 

Enclosures:  Resume  Application Letter of Recommendation

• Formatting:  Make sure you use the correct singular or plural form of “enclosure” depending on how many items you’re enclosing!

Software Engineer Cover Letter Mistakes to Avoid

• If you’re applying to work as a software engineer, you and your reader share a mutual, unspoken understanding that you’re working at a pretty advanced level in your field. All the same, make sure you don’t assume recruiters know exactly what you’re talking about and get vague about software knowledge—especially when you could enrich your software engineer cover letter with specific names like C# and JavaScript.
• We understand: You’re probably laser-focused on the technicalities of what you can build and test to ensure client satisfaction each day. However, it’s still important to be able to communicate your expertise to other team members or other departments. Collaboration is a huge part of the software engineering role since you’ll coordinate with other teams to communicate your engineering vision and ensure optimal results.
• In an engineering role of any kind, recruiters will take this as a bad sign—if you can’t give your cover letter a sound structure, how effective would you really be in their open job role? Organization and lack of precision can render a software engineer’s work buggy or even unusable! Make sure recruiters know you’ll eliminate this problem by organizing your cover letter thoroughly, reading it again for flow and checking for quantifiable examples of past successful creations.
• Again, attention to detail is as crucial as your ability to problem-solve during the software engineering (and troubleshooting!) process. Make sure you demonstrate your ability to conduct relevant research and find solutions efficiently by seeking out the name of the person your cover letter is going to! Writing a strong introductory paragraph afterward will help your case, too: Briefly outline a few personal traits and skills that will help solve the problems presented in the job description.

Before You Land Your Dream Software Engineering Role

We know you’ve probably put a lot of thought into your cover letter as a software engineer—after all, analytical thinking and strategic planning are among your strong suits! However, while your cover letter is important to refine and perfect, you’ll need to  write a winning resume , too.

Even if you already have a resume, chances are it’s gotten a bit dusty. Take the opportunity to  check your resume  over for a quick refresh. Browse through our  software engineer resume examples  or start editing this one here if you’re ready to knock it out. 

Software Engineer Resume

Easing your job hunt and taking your career to the next level is possible with the tools and  resume tips  we offer. Once you nail down the perfect cover letter and resume, recruiters will know why you’re such a great hire. They’ll be hard-pressed to turn you down as a result! 

You’ve already covered coding in your software engineer resume , mentioning languages and frameworks like Python or Angular. Use your cover letter to elaborate on them and show how you leveraged them to make an impact. For example, discuss a project you’re particularly proud of—such as a fully responsive web app—and attach a link to it so the hiring manager can check it out.

Software engineering is a highly dynamic field, so you’re in luck! Emphasize transferable skills and experience in your cover letter to earn brownie points. For instance, express how your background in teaching means you’ll be good at conversing with a non-technical audience or how your previous job in retail taught you attention to detail.

Senior software engineers are no strangers to headhunting, so you may have job offers lined up a lot of the time. However, for a job that you actually care about, you should always attach a cover letter. It shows that you respect the company, and it gives you a chance to express why you want to work there instead of anywhere else.
