What this role is
Join Supabase to build Spark, a lightweight, embedded Postgres-compatible database written in Rust that brings full backend capabilities to AI prototypes and edge environments. You'll own large technical areas end-to-end on a small founding team, from API compatibility and database internals to developer tooling and the upgrade path to production Supabase.
