Example software engineer cover letter

Dear Hiring Manager, I build backend systems that stay fast under load, and your Software Engineer opening at Northwind is exactly that kind of work. In my current role at a SaaS company, I rebuilt our order API in Go and PostgreSQL, cutting p95 latency from 900 ms to 180 ms while traffic doubled. I also introduced contract tests that stopped a class of breaking changes from reaching production. I'd bring the same focus on measurable reliability to your team. I'm particularly drawn to Northwind because of its focus on [a specific product, value or project]. I would welcome the chance to discuss how I could help your team. Kind regards, Alex Morgan
