Edge Functions Engineer

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. Edge Functions https://supabase.com/docs/guides/functions are server-side TypeScript functions, distributed globally at the edge - close to your users. They power use cases such as webhook receivers, AI inferences, OG image generation and real-time bots (Slack, Discord, etc). Built on top of Supabase Edge Runtime https://github.com/supabase/edge-runtime: an open-source, Deno-based runtime written in Rust that runs JavaScript, TypeScript, and WASM services. We want developers to be able to build truly global applications by distributing both compute and data globally. Infrastructure concerns like regions, cold starts, CPU and memory provisioning should fade into the background so developers can focus on iterating on business logic. We are looking for experienced and passionate engineers to help us go further in this vision. 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. WHAT WE OFFER - Fully Remote We hire globally. We believe you can do your best work from anywhere. There are no Supabase offices, but we provide a WeWork membership or co-working allowance you can use anywhere in the world. - ESOP Every team member receives ESOP (equity ownership) in the company. We want everyone to share in the upside of what we’re building together. - Tech Allowance Use this budget to set up your ideal work environment—laptop, monitor, headphones, or whatever helps you do your best work. - Health Benefits Supabase covers 100% of health insurance for employees and 80% for dependents, wherever you are.

It’s a highlight of our year. - Flexible Work We operate asynchronously and trust you to manage your own time. You know what needs to be done and when. - Professional Development Every team member receives an annual education allowance to spend on learning—courses, books, conferences, or anything that supports your growth. ABOUT THE TEAM Supabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love. - ~400 team members - 60+ countries - 20+ languages spoken - Over $1B raised (including our $500M Series F) - 540,000+ community members We move fast, build in public, and use what we ship. If it’s in your project, we probably use it in ours too. We believe deeply in the open-source ecosystem and strive to support—not replace—existing tools and communities.
