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 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 : 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.
