What does a Senior Software Engineer actually do?
A senior software engineer owns whole services and multi-sprint features rather than tickets, making the design calls, reviewing what teammates ship, and carrying production accountability when something breaks. In Indian product companies and GCCs the level usually starts around five years in, and is judged on technical judgement, mentoring and delivery predictability far more than raw coding speed.
Hiring managers filling a Senior Software Engineer role usually expect 5–10 yrs of experience. The duties they weight most heavily are the ones your letter should mirror:
- Own the design and delivery of a service or feature area across multiple sprints
- Write design documents and defend the trade-offs in architecture review
- Review teammates' pull requests for correctness, security and long-term maintainability
- Mentor two or three junior engineers through pairing, feedback and structured ramp-up
