Software Engineer Cover Letter Example (Short, Specific, No Fluff)
Most engineering managers skip cover letters. The ones who read them want three things: what you built, the effect it had, and a sign you understand their product. Keep it to 200 words.
Fictional applicant Jordan Lee applying for Software Engineer, Payments at Ferry Financial.
Hi Ms. Nakamura, I am applying for the Software Engineer role on the Payments team at Ferry Financial. I spent the last three years at Tallgrass Logistics building the service that reconciles carrier invoices against shipments. It handles about 40,000 invoices a day in Go and Postgres, and when I rewrote the matching step to run as an idempotent queue consumer, the reconciliation backlog went from two days to under an hour and the on-call pages for that service dropped to almost none. Before that I worked on a small team where I owned the Stripe integration end to end: webhooks, retries, refunds, and the ledger entries that finance closed the month against. I learned to write the boring tests first, the ones that catch a double charge. I read Ferry's engineering post on moving ledger writes to an outbox pattern. That is the kind of problem I want to work on, and I have opinions about the retry policy that I would enjoy arguing about in an interview. My résumé and GitHub are attached. Thanks for reading.

Why this letter works
- Name the system, the language, the scale, and the change. Numbers for volume and latency.
- One paragraph about ownership of something adjacent to their domain (payments, data, infra).
- Reference one real artifact from the company: a blog post, an open-source repo, a changelog.
- Under 220 words. A long engineering cover letter reads as a warning sign.
