About the role

Develop and maintain authentication features for Supabase Auth, focusing on secure, scalable Go and TypeScript implementations, client/server integration, and observability across a large Postgres-based infrastructure.

Responsibilities

  • Designing and implementing secure, scalable authentication features in Go and TypeScript.
  • Working across the stack: from server-side protocols to client-side libraries for frameworks like Next.js.
  • Owning the performance, reliability, and scalability of the Auth server across Supabase's infrastructure.
  • Contributing to the evolution of our Auth architecture, including support for OAuth, OIDC, SAML, and other protocols.
  • Planning and executing safe database migrations across a large fleet of Postgres instances.
  • Building and improving observability: metrics, tracing, alerting, and dashboards to keep the system healthy at scale.
  • Writing and reviewing RFCs as part of our product development process.
  • Collaborating with engineers across Supabase to ensure a seamless experience for developers using our tools.
  • Supporting the community and responding to developer feedback on GitHub, Discord, and other channels.

Qualifications

  • 4+ years of professional experience writing and shipping Go in production.
  • 2+ years of professional experience working on an authentication system (implementing protocol support, maintenance at scale).
  • Strong relational database experience (Postgres or MySQL); Postgres experience is a bonus.
  • Strong knowledge of TypeScript in addition to Go (languages used daily).
  • Strong knowledge of web technology fundamentals (cookies, sessions, JWT, HTTP, browser APIs).
  • Good knowledge of and deep interest in authentication security (passwords, protocols such as OAuth, OIDC or SAML, cryptography fundamentals such as hash functions, signatures and ciphers).
  • Experience with multiple web frameworks like Next.js (or other SSR) and traditional web frameworks like Ruby on Rails, Django, Laravel or equivalent.
  • Good technical writing skills (RFC process is an important part of making changes to the Auth product).
  • Hands-on experience building and operating services at significant scale.
  • Deep understanding of systems-level concerns: memory management, concurrency patterns, and compute resource optimization in Go.
  • Experience with Kubernetes and AWS (or comparable cloud platform) in a production setting.
  • Solid grasp of observability practices — metrics, distributed tracing, structured logging, and alerting (e.g., Prometheus, Grafana, OpenTelemetry).
  • Experience managing database schema migrations safely at scale.
