Edge Functions Engineer

• Work on Edge Functions, server-side TypeScript functions distributed globally at the edge, powering use cases such as webhook receivers, AI inferences, OG image generation, and real-time bots. • Evolve Supabase Edge Runtime, an open-source Rust-based host that runs the Deno isolate, manages the main/user runtime split, and enforces per-request memory and CPU limits. • Help developers build truly global applications by making infrastructure concerns like regions, cold starts, and resource provisioning fade into the background.

• Bring at least 5 years of backend or systems engineering experience with strong fluency in both Rust and TypeScript. • Have experience with V8 Isolates, Deno, and JavaScript runtimes in general. • Have experience operating infrastructure at scale using Kubernetes, AWS, Cloudflare Workers, Redis, or comparable systems. • Hold a strong vision for how compute and data can be pushed to the edge.

• Have experience building developer-facing CLIs or front-end tooling that sits on top of an infrastructure product. • Bring experience contributing to upstream open-source projects such as Deno or other runtime ecosystems. • Have experience implementing OpenTelemetry tracing and observability across runtime systems. • Have worked with WebSockets streaming, scheduled functions, or background task systems in production.

• Evolve Supabase Edge Runtime, the open-source Rust-based host that runs the Deno isolate and enforces per-request memory and CPU limits. • Implement monitoring, alerting, and OpenTelemetry tracing across the runtime, using that visibility to drive optimisations that improve latency and reliability. • Work closely with the Deno and other open-source teams, contributing upstream and relaying user requirements. • Participate 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. • Integrate functions more tightly with the rest of the Supabase stack including Auth, Postgres, Storage, and Realtime. • Expand functions to support more use cases such as AI inference, MCP servers, hosting simple websites, and URL shorteners. • Improve the developer experience of developing and debugging functions locally through the Supabase CLI including DevTools integration, logging, and production parity.

• Work fully remotely from anywhere in the world. • Receive ESOP equity ownership in the company. • Get a tech allowance to set up your ideal work environment. • Receive 100% employer-covered health insurance with 80% coverage for dependents. • Attend annual company off-sites in a new city each year. • Work flexibly and asynchronously with full trust to manage your own time. • Receive a professional development allowance for courses, books, conferences, and learning. • Access a WeWork membership or co-working allowance usable anywhere in the world.
