Edge Functions Engineer

What You’ll Own

• Evolving Supabase Edge Runtime - an Open-sourced Rust-based host that runs the Deno isolate, manages the main/user runtime split, and enforces per-request memory and CPU limits.
• Implementing monitoring, alerting, and OpenTelemetry tracing across the runtime, then using that visibility to drive optimizations that improve latency and reliability of the service.
• Working closely with the Deno and other open-source teams, contributing to upstream and relaying our users' requirements.
• Participating in an on-call rotation to keep Edge Functions healthy in production.
• Help manage and improve features like scheduled functions, background tasks, WebSockets streaming, ephemeral file storage, and custom routing.
• Integrating functions more tightly with the rest of the Supabase stack - Auth, Postgres, Storage, and Realtime.
• Expanding functions to support more use cases (AI inference, MCP servers, hosting simple websites, URL shorteners).
• Improving the DX of developing and debugging functions locally through the Supabase CLI, including DevTools integration, logging, and production parity.

What You’ll Bring

• At least 5 years of backend or systems engineering experience, with strong fluency in Rust and TypeScript.
• Experience with V8 Isolates, Deno and the JavaScript runtimes in general.
• Experience operating infrastructure at scale - Kubernetes, AWS, Cloudflare Workers, Redis, or comparable systems.
• A strong vision for how compute and data can be pushed to the edge.
• Bonus: experience building developer-facing CLIs or front-end tooling that sits on top of an infrastructure product.
