About the role

Own a service end to end its API contracts, data model, integration patterns, performance, security posture and behaviour in production. Roughly 70% backend and 30% frontend in React. You will work independently, contribute to architectural decisions, mentor one engineer, carry on-call, and act as the technical point of contact for your service with enterprise client stakeholders.

What you will do
- Own API contracts and service boundaries versioning, idempotency, backward compatibility.
- Own the data model: schema design, indexing strategy, query performance and zero downtime migrations.
- Design integration patterns between services, including asynchronous messaging where appropriate.
- Own caching with a real invalidation approach, and service performance N+1 removal, slow-query tuning, latency percentiles.
- Own security (object-level authorisation, validation, secrets, dependency risk) and observability (structured logs, metrics, traces, actionable alerts).
- Carry on-call,



debug production incidents across service boundaries and author the root cause analysis.
- Own the test strategy and contribute to CI/CD, release strategy and rollback safety.
- Mentor one engineer, review pull requests, and explain architecture and delivery risk to clients.

What we are looking for

- Solid NestJS or equivalent modules, dependency injection, guards, interceptors, pipes, exception filters.
- Demonstrated ownership of API and service design, including versioning and idempotency.
- Deep PostgreSQL: schema design, EXPLAIN plans, index strategy, transactions, safe migrations. Working MongoDB experience.
- Production Redis or equivalent caching, with an invalidation strategy. Production asynchronous messaging (Kafka or RabbitMQ) consumer groups, ordering, retries, dead-letter handling.
