Developer Infrastructure Engineer

About this role

Engineering builds and runs TalentOS — the hiring platform this careers site is itself running on. Job search, the application flow, the recruiter console, and the services underneath all of it.

Own the inner loop: build times, test reliability, CI throughput and local environments. Success is measured in how long an engineer waits, and in how often they trust a red build.

The platform is multi-tenant and the correctness bar is unusually high for a product of its size: an application that goes missing is somebody's career, not a support ticket. Traffic is spiky by nature — a campus placement season concentrates a year of applications into a fortnight — so capacity and queueing are ordinary design concerns rather than scaling exotica.

Primary responsibilities

• Own the inner loop: local development, the build, CI, and how long an engineer waits to know whether their change works
• Keep the pipeline fast and, more importantly, trustworthy — a flaky test suite is worse than a slow one
• Build and maintain the ephemeral environments that let a pull request be reviewed as a running thing
• Own artifact building, caching and dependency management across the monorepo
• Track and publish the metrics that matter — build duration, test flakiness, time from commit to production

Skills required

Day to day this role works with CI/CD, Build Systems, Testing Infrastructure and Developer Experience.

• Six or more years on developer infrastructure or build systems
• Four or more years on CI, build or developer tooling
• Monorepo tooling and build caching
• Container-based build and test environments
• A record of attacking test flakiness rather than tolerating it
