Senior DevEx Engineer - Infrastructure

Responsibilities

• Own Primer's internal developer platform end to end: the CI/CD pipelines, deployment workflows (canary, blue/green), self-service tooling and ephemeral environments that every engineer here depends on to ship.
• Build the human-AI development loop. This is the most open part of the role: the tooling and automation that let engineers work effectively alongside coding agents, and the patterns that make agent-driven workflows fast and safe at Primer.
• Set the technical direction for how Primer's engineers build and ship, and bring less experienced engineers along with you as you do it.
• Build Primers paved roads. Reduce the application boilerplate engineers write, shape standards around how services are built and configured, and own the golden-path tooling that lifts efficiency across every team.
