About the role

Key responsibilities & impact

Accelerate software delivery by designing and building internal tools and services that reduce friction for engineering teams.
Own and evolve our CI/CD infrastructure, not just maintain it, but rethink how it should work as we scale
Build and maintain paved paths: reusable patterns and templates that make the right defaults obvious and easy to follow
Build release engineering tooling that gives engineers confidence and control over how their code ships
Identify bottlenecks in developer workflows through close collaboration with engineering teams, then build lasting solutions, not workarounds
Contribute to the architectural decisions that will shape how 200+ engineers build and ship software and images
Help shape how the Platform Engineering team itself operates: our processes, priorities, and our push toward a self-service engineering org
Participate in an on-call rotation and keep the systems you own well-documented, reliable, and observable

Requirements

What you’ll need

5+ years of experience in platform engineering, release engineering, developer tooling, or a closely related discipline
You write production-quality software and treat internal tooling as a product: real users, real quality standards, and things that actually get adopted (Go and/or Python preferred)
Deep experience with CI/CD systems (e.g. Buildkite, GitHub Actions), not just configuring them, but extending and building on top of them
Strong foundation in infrastructure-as-code (Terraform) and cloud environments (AWS or GCP)
Experience designing and building agentic workflows that automate meaningful parts of the software delivery lifecycle
Builds for the many, not for one team or one use case
Distills the right problem out of the noise: asks the why behind the why
Outcome driven and measures the impact of what you ship
Comfortable with ambiguity and energized by defining the problem before solving it
