Senior Postgres Security Engineer

We’re looking for a senior PostgreSQL engineer with deep expertise in PostgreSQL internals and proven experience developing extensions in both C and Rust. You should have strong knowledge of PostgreSQL's permission model and security features, including RLS, roles, and grant systems. Experience troubleshooting production issues in managed PostgreSQL environments is essential - you'll need to diagnose and resolve complex problems involving custom extensions, performance bottlenecks, and resource contention. You should be comfortable building testing and owning idempotent deployment to many thousands of running Postgres instances. You should be comfortable diving into PostgreSQL source code, understanding the query planner, executor, and storage engine mechanics. Previous experience with multi-tenant database architectures and working with PostgreSQL at scale is highly valued.
