Software Engineer - AI Tooling Infrastructure

Job description

About Supabase Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. About the Role We’re looking for a Software Engineer, AI Tooling Infrastructure to join our AI Tooling team and help build and run the backend services behind Supabase’s AI products. The Supabase MCP server is one example of what the team runs in production, alongside the services that support agent skills and the dashboard assistant. You’ll work closely with the Platform, SRE, Auth, Billing and Edge Functions teams, and with the engineers on the AI Tooling team who build the product surfaces.

What You’ll Be Responsible For In this role, you’ll: Build and operate the production backend services behind Supabase’s AI products, including the MCP server: deployment, scaling, configuration and release. Take ownership of how those services are structured, including splitting or reshaping a service when that makes it safer to run and easier to change. Define, measure and meet reliability targets for the services the team runs. Set SLOs with the SRE team, track error budgets, and use them to decide what to fix first. Participate in the AI Tooling team on-call rotation, and be a first responder for incidents in those services. Investigate, fix, coordinate with other teams during incidents, and write the follow-ups and runbooks. Work the AI Tooling team support queue alongside on-call, and turn recurring issues into fixes rather than repeated manual answers. Own authentication and authorization for AI and agent clients:…
