• Have deep understanding of systems-level concerns: memory management, concurrency patterns, and compute resource optimization in Go.

• Have experience with Kubernetes and AWS (or comparable cloud platform) in a production setting.

Supabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love.

• ~400 team members

• 60+ countries

• 20+ languages spoken

• Over $1B raised (including our $500M Series F)

• 540,000+ community members

We move fast, build in public, and use what we ship. If it's in your project, we probably use it in ours too. We believe deeply in the open-source ecosystem and strive to support - not replace - existing tools and communities.
