AI SummarySupabase is seeking a senior Edge Functions Engineer to evolve its Rust-based, Deno-powered edge runtime for globally distributed TypeScript, JavaScript, and WASM workloads. The role combines systems programming, runtime engineering, observability, production reliability, and integration with Supabase services such as Auth, Postgres, Storage, and Realtime. Key work includes improving latency and reliability, contributing upstream with Deno and open-source communities, enhancing developer tooling, and supporting production through an on-call rotation. This is a fully remote, globally distributed role requiring strong Rust and TypeScript skills plus experience operating infrastructure at scale. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 5/5EasyHard ### Pace & Pressure 5/5RelaxedFast-paced ### Autonomy Level 5/5GuidedFull ownership ### Communication Load 4/5IndependentCollaborative AI insightThis is a highly specialized senior systems role involving Rust, V8/Deno runtime internals, distributed edge infrastructure, observability, and production operations.

I would then prioritize changes with the largest measured impact, such as isolate pooling where safe, caching compiled modules, reducing initialization work, and improving placement or prewarming strategies, validating each change against latency, memory, and isolation requirements. What considerations matter when enforcing per-request CPU and memory limits for untrusted edge-function workloads? The controls need to be measurable, difficult to bypass, and safe for multi-tenant execution. I would use runtime- and host-level limits, account for asynchronous work and child resources, define clear cancellation behavior, and emit structured events when limits are approached or exceeded. The design should balance tenant isolation with predictable developer-facing error messages and minimal overhead. Describe how you would implement useful OpenTelemetry observability for an edge runtime. I would propagate trace context across ingress, routing, runtime execution, outbound requests, database calls, and platform services. Core telemetry would include request latency, cold versus warm starts, CPU and memory usage, errors, throttling, queue depth, and regional health, with carefully designed cardinality controls. Dashboards and alerts should focus on user impact, while sampled traces support investigation of individual slow or failed executions. How would you approach contributing a needed runtime capability upstream to Deno or another open-source dependency? I would begin by reproducing the requirement with a minimal test case and understanding the project’s architecture and contribution process. I would propose the design early, explain Supabase’s production use case, implement a focused and well-tested change, and respond constructively to maintainer feedback. If upstream timelines differ from platform needs, I would maintain a minimal compatible workaround while continuing to pursue the upstream solution. How would you improve local development and debugging parity for edge functions? I would identify the production behaviors that are hardest to reproduce locally, including environment variables, routing, permissions, limits, logging, network behavior, and service integrations. Then I would build CLI workflows and DevTools hooks that make those behaviors visible, provide actionable diagnostics, and enable repeatable local tests. The goal is to ensure developers can detect deployment-time issues before release without making the local workflow unnecessarily complex. ### 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. Your wellbeing and your family’s health are important to us. * Annual Off-Sites Once a year, the entire company gathers in a new city for a week of connection, collaboration, and fun. 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.
