Hire Node.js developers who have run services in production
Centricone places backend engineers who have operated Node services, not only written them — the difference shows up the first time something leaks memory under load.
Screening
What we check that a keyword match does not
Every candidate sits a live assessment with an engineer who does this work. For this role, that conversation covers:
- API design: versioning, error contracts, and idempotency on retryable operations
- Async reasoning — where the event loop blocks and how they would find it
- Database access patterns, including the N+1 they should recognise on sight
- Production instincts: logging, tracing, and what they would alert on
What they do once they are in your team
Building and maintaining REST or GraphQL services
Integration work between systems that were never designed to talk
Performance and memory investigation under real load
Queue, retry, and dead-letter handling for work that must not be lost
Which level you actually need
Most briefs ask for senior by default. Sometimes that is right; often the work is better served by a mid-level engineer and a clearer specification.
Delivers endpoints and services within an established architecture, with review on data modelling and failure handling.
Designs service boundaries and data access, and is the person who diagnoses the production problem at 2am.
Owns backend architecture across services, sets standards, and carries delivery accountability.
