Cover letter example: Software Developer

For a software developer role, an effective cover letter proves your technical level through concrete results (not a list of technologies), shows you understand the company's product, and reuses the languages and frameworks the posting requires. Stay factual and quantified.

Example letter

Dear Hiring Manager,

Your back-end developer role around Node.js and PostgreSQL caught my attention: it is exactly the stack on which I cut API response time by 40% for a service handling 200,000 requests a day.

A developer for 5 years, I have built services in TypeScript, set up automated testing (coverage from 35% to 80%), and mentored two junior developers through code review. Your product approach, centered on measuring impact, matches the way I work.

I would be glad to discuss how I can contribute to your team.

Skills to highlight

• The exact languages and frameworks from the posting (only list what you truly know).
• Measurable impact: performance, reliability, volume, delivery time.
• Engineering practices: testing, CI/CD, code review, agile.
• A concrete project with a link (GitHub, portfolio) placed in the CV.

Tailor this example to your profile

Swap the stack, numbers, and project for your own. Reuse the exact job title and 2 or 3 key requirements from the posting. Replace generic jargon ("passionate about technology") with proof.
