About the role

We’re building a high-performance CI/CD execution platform similar to runners used by tools like Buildkite, GitHub Actions, and Blacksmith CI.

In this role, you will design and build the distributed systems responsible for running CI/CD pipelines securely and efficiently.

This includes orchestrating ephemeral compute environments, managing build isolation, scheduling jobs across fleets of workers, and ensuring reliability at scale. This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions. What You’ll Be Responsible For Design and improve the core orchestration engine that manages the lifecycle of creating, merging, and rebasing Supabase Branches.

Provision ephemeral sandboxed execution environment on EKS / ECS for running untrusted build workloads from connected git repositories with securely managed secrets. Implement job scheduling that scale to thousands of concurrent builds. Optimize and reduce pipeline runtimes with caching, artifact storage, and dependency reuse.
