Senior Software Engineer job description template
A template you can use, plus the part most templates skip: how to assess each requirement once candidates start applying.
A senior software engineer is trusted with ambiguous problems and with raising the standard of the people around them. The distinction from a mid-level engineer is scope and judgement, not years served. A good senior software engineer job description separates genuine must-haves from preferences, describes what the person will actually do, and defines the criteria interviewers will assess against.

Keep the essential list genuinely essential. Long requirement lists measurably reduce applications from candidates who would meet your actual bar, with a stronger effect among under-represented groups. Everything you can train, move to nice-to-have.
How to assess each requirement
This is the part most job description templates omit, and it is the part that determines whether the description was worth writing. Each requirement needs a way to test it:
| Requirement | How to assess it |
|---|---|
| Track record owning systems in production, not just features | Ask: "What is the largest system you have been responsible for, and what does "responsible" mean there?" |
| Demonstrated influence on other engineers' work | Ask: "Tell me about a technical decision you made that turned out to be wrong." |
| Ability to make decisions with incomplete information and revisit them | Ask: "How do you decide between fixing something properly and shipping a workaround?" |
| Communicates technical trade-offs to non-technical stakeholders | Ask: "Describe how you took an ambiguous problem and made it something a team could work on." |

On salary
Publish a range. Pay transparency requirements are expanding across the EU and parts of the US, candidates increasingly filter out roles without one, and omitting it mainly advantages whoever negotiates hardest — which correlates with confidence rather than contribution. See compensation bands.
