In this role, you’ll

• Investigate and resolve advanced customer issues across Postgres, Auth, RLS, Storage, Realtime, Edge Functions, and client libraries.

• Communicate clearly and empathetically with customer users of all levels—especially during high-impact or time-sensitive situations.

• You’re strong in high-performance SQL and query optimization.
• You’re comfortable troubleshooting complex setups, including multi-tenant schema patterns.
• You can debug edge functions and understand distributed system behavior when failures get tricky.

• You have hands-on experience with cloud hosting providers like AWS.
• You’re comfortable in terminal and Linux environments.
• You thrive in high-volume situations and can form/test assumptions quickly.
