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. Expanding functions to support more use cases (AI inference, MCP servers, hosting simple websites, URL shorteners). Improving the DX

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 SDK Engineer - JavaScript to join the SDK team and own a core part of how developers talk to Supabase from JavaScript and TypeScript. Our JS/TS SDKs are the front door to the platform: database queries, auth, storage, realtime subscriptions and edge functions, used by a very large number of developers and by most of the AI coding tools building on Supabase today. This is a library-authoring role, and the work happens in the open: public repos, public issue trackers, and API decisions whose consequences are permanent. The type system here is a design surface rather than a formality. If you get satisfaction from an inference that Just Works, from a migration guide that saves people an afternoon, and from an issue tracker that isn't a graveyard, you'll like it here. This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions. What You'll Be Responsible For Build and evolve our JavaScript/TypeScript SDKs. Start new things. Alongside the maintenance work, you're expected to find what's missing, make the case for it, and build it. Some of what we ship next doesn't exist yet, and nobody will hand you the list. Work in the open. These are public repos: you'll triage inbound issues, review and shepherd outside contributions, keep CI and release automation healthy, and hold a clear, kind line on scope. Own the type experience. Keep generated database types flowing correctly through the client APIs so autocomplete and inference stay correct in real codebases. Keep us honest across runtimes. Node, Deno, Bun, browsers, Cloudflare Workers, React Native/Expo, including dual ESM/CJS publishi
