We're building the world's fastest change data capture (CDC) platform for Postgres. CDC is a proven pattern that enables real-time use cases like triggering side effects, fanning out events, caching at the edge, and audit logging - but existing solutions are notoriously difficult to set up and maintain.
We're making CDC easy enough for weekend projects yet robust enough for Fortune 500 companies.

What makes this role exciting:
- Join an early-stage open source project with significant technical influence
- Build a tool you would use for a user you understand
- Work deeply with Postgres
- Solve novel distributed systems challenges (not building CRUD apps)
- Work with Elixir/Phoenix and OTP primitives in production
