Engineering Recruiting Team
[Company name]
[City, State]

Dear [Hiring manager's name],

Last summer at Fernwood Apps, a five-person startup, I was the only intern on a team small enough that my code went straight to production the same week I wrote it, which taught me more about real engineering tradeoffs than two years of coursework had. I'm applying to [Company name]'s internship because I want to keep learning at that same speed, on a team with more experienced engineers to learn from.

I built a notification-preferences feature that shipped to all 8,000 of Fernwood's active users, and after noticing our email open rate sitting at 11%, I proposed and built a send-time optimization that raised it to 19% over the following month. Outside of that, a class scheduling app I built for fellow students is now used by about 600 people at my university every semester.

I'm most comfortable in Python and JavaScript, picked up React and a fair amount of SQL on the job at Fernwood, and I'm currently taking algorithms and database systems courses that I try to immediately apply to whatever I'm building. I contribute to one open-source project on GitHub and have started reading pull requests there just to learn how experienced engineers give feedback.

I'd welcome the chance to talk about what [Company name]'s engineering interns typically work on and where someone who ships fast and asks a lot of questions could contribute. I'm available for an interview at your convenience. Thank you for considering my application.

Thank you,

Taylor Davis

Why this letter works

  1. Paragraph 1

    Turns small-team chaos into a selling point

    Framing a five-person startup's lack of process as an accelerated learning environment, rather than apologizing for its informality, shows self-awareness recruiters respond well to in an intern candidate.

  2. Paragraph 2

    A shipped feature plus a self-directed fix

    Naming the user count for a shipped feature, then a metric he noticed and improved on his own initiative, shows both execution and curiosity, which matters more for an intern than any single technology listed.

  3. Paragraph 3

    Honest about what's still coursework

    Being specific about which skills came from the job versus current classes reads as more credible than implying mastery, and shows a student actively connecting what he's learning to what he builds.

Questions about software engineering intern cover letters

Do I need a cover letter for a software engineering internship?

Many applications don't require one, but a short letter helps you stand out when a company reviews hundreds of similar resumes. Use it to describe one project in enough detail that a recruiter can picture what you actually built, not just list your coursework.

What should I include if I only have one internship or class projects?

Pick your strongest project, whether it's from an internship, a class, or something you built on your own, and describe what you built, who used it, and one result, even a small one. A specific project beats a long list of technologies every time.

Should I mention my GPA or coursework in an internship cover letter?

Only if it's genuinely strong or directly relevant to the role, and keep it brief. Recruiters weigh what you've actually built more heavily than coursework, so spend most of the letter on a project rather than your transcript.
