Technical criteria — MUST HAVE

Strong TypeScript and Node.js (server-side)

- Builds backend services in TypeScript, not just front-end work
- Comfortable in a large, strictly typed codebase

API design and contract management

- Can diagnose issues without full administrative access by working with platform teams

Observability/Monitoring and Debugging across distributed systems

- Uses logs, traces and correlation IDs systematically rather than by trial and error

Testing discipline

- Experience with modern testing tools (e.g. Vitest/Jest, Playwright or similar)

Modern CI/CD and version control practices

- Works comfortably with git, automated pipelines, feature flags, release candidates and rollback
- Experience in a shared monorepo environment is an advantage

Security and compliance awareness in regulated systems

- Apollo Federation (version 2)
- Apollo GraphOS or Rover tooling — schema validation and monitoring
- Prometheus and Grafana for monitoring
- API gateway experience -Kong specifically
- MCP (Model Context Protocol) — building or running an MCP server

Non-technical criteria

Excellent communication

- Provides updates proactively rather than waiting to be asked
- Raises blockers early, with context and a suggested way forward

Self-motivated with strong ownership

- Takes a loosely defined problem and comes back with a plan

- Sees work through to completion, including the less interesting final detail

Product and business-analysis thinking





- Asks why something is needed before deciding how to build it
- Spots missing requirements, edge cases and customer impact

Genuinely switched on

- Absorbs new context quickly and connects information across different systems
- Works things out from first principles where documentation is missing or out of date

Collaborative team member

- Reviews colleagues' work properly, pairs when it helps, shares what they learn
- Can disagree on technical matters without creating friction

Reliable delivery at sprint cadence

- Breaks work into realistic pieces and give estimates they can stand behind
- Flags slippage as soon as it becomes likely, not at the end of the sprint

Pragmatic judgement on quality versus speed
