Confirmed on the employer's own hiring board on Oct 14, 2026. First seen by Alion on Jul 23, 2026. Chainlink scores B on the Alion truth index.
Join Chainlink Labs as a Senior Site Reliability Engineer (DevEx) and play a crucial role in building the infrastructure that powers our CI/CD platform, developer environments, and build systems. You will design and build the Kubernetes-based control plane, develop core infrastructure components, and shape the reliability and scalability of the developer experience across the entire engineering organization. This is not an operational support role; you will be building the systems that define how engineering teams build, test, and deploy.
Missions
- Concevoir et construire les primitives d'infrastructure qui définissent la manière dont notre plateforme CI/CD, nos systèmes de construction et nos environnements de développement évoluent à l'échelle de l'ensemble de l'organisation d'ingénierie.
- Développer les composants d'infrastructure de base, y compris les opérateurs Kubernetes et l'automatisation de mise à l'échelle, que les équipes produit adoptent directement, réduisant ainsi les outils CI/CD et d'environnement sur mesure par équipe.
- Construire et exploiter le plan de contrôle basé sur Kubernetes derrière notre plateforme CI/CD, y compris l'infrastructure des runners auto-hébergés GitHub Actions, les applications GitHub et GitHub-as-code.
