Backend Developer job description template
A template you can use, plus the part most templates skip: how to assess each requirement once candidates start applying.
Backend developers build the services, APIs and data layers behind a product. The work is dominated by correctness, failure handling and the cost of changing decisions once data has accumulated behind them. A good backend developer job description separates genuine must-haves from preferences, describes what the person will actually do, and defines the criteria interviewers will assess against.

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 |
|---|---|
| Production experience with a server-side language and a real database | Ask: "Describe an API you designed. What would you change about it now?" |
| Understanding of API design and versioning | Ask: "How have you handled a schema change on a large table in production?" |
| Awareness of common security failure modes | Ask: "A downstream service starts failing intermittently. How do you make your service resilient?" |
| Experience operating something they built, not just shipping it | Ask: "How do you think about idempotency?" |
Full question set with strong and weak answer guidance: backend developer interview questions.
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.
