Cover letter examples

software engineer cover letter example (2026)

A software engineer cover letter should name the stack in the posting and one system you owned — not a passion paragraph about coding since childhood.

When this letter is worth sending

Send one when the form allows it, when you are changing domains, or when the posting is senior enough that a human will open attachments.

Example letter (teaching draft)

Fictional names and companies. Copy the structure, not the metrics. If you cannot discuss a line in an interview, delete it.

Dear Hiring Manager,

I am applying for the Software Engineer role because your posting asks for TypeScript services with real on-call ownership — that is the work I have been doing on checkout APIs.

At Northwind I owned the checkout API (Node, Postgres). We cut p95 latency on catalog reads by putting a cache in front of the hot path, and I can walk through the failure mode we hit when the cache stampeded. Before that I shipped billing-settings UI in React so self-serve customers could update invoices without a ticket.

I noticed you are hiring into a team that still runs a monolith-to-services split. I have done that split on a smaller surface and I review before I send.

I would welcome 20 minutes on the role and the on-call rotation.

Best,
Alex Patel
