Overview
The senior engineer works across the development lifecycle of backend services within an online gaming product and technology organisation. Features need clear implementation, reusable code and appropriate testing before deployment. Problems can arise in development, test or production environments, so debugging and operational understanding remain part of normal delivery. The role also supports team discussions and formal proposals for changes, helping improvements move through an agreed review process. As an initial on-call responder for the team’s software, the engineer connects implementation choices with real production behaviour. The technical focus includes high-traffic distributed systems, messaging, concurrency and the APIs that connect services.

- Distributed-system and messaging experience.
