Edge Functions Engineer

About the Role

The Edge Functions Engineer will be part of a remote team that values collaboration, openness, and async communication. You will have the opportunity to work with a talented team of engineers who are passionate about building truly global applications.

Supabase is committed to providing a flexible and supportive work environment that allows engineers to do their best work from anywhere. With a strong focus on remote work, the company provides a WeWork membership or co-working allowance, as well as a tech allowance to set up your ideal work environment.

What You Will Do

• Evolve 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.
• Implement monitoring, alerting, and OpenTelemetry tracing across the runtime, then use that visibility to drive optimizations that improve latency and reliability of the service.
• Work closely with the Deno and other open-source teams, contributing to 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 - 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 DX of developing and debugging functions locally through the Supabase CLI, including DevTools integration, logging, and production parity.

What We Are Looking For

• 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.
• Strong communication and collaboration skills, with the ability to work asynchronously with a remote team.

Nice to Have

• Experience with other programming languages, such as Java, Python, or C++.
• Familiarity with containerization using Docker and Kubernetes.
• Knowledge of cloud-native technologies, such as serverless computing and container orchestration.

Benefits and Perks

• Fully remote work arrangement, with a WeWork membership or co-working allowance.
• ESOP (equity ownership) in the company, with a shared vision for the future.
• Tech allowance to set up your ideal work environment.
• Health benefits, with 100% coverage for employees and 80% for dependents.
• Annual off-sites, with a week-long gathering of the entire company in a new city.
• Flexible work arrangement, with async communication and a focus on results.

• Make sure to highlight your experience with Rust and TypeScript in your resume and cover letter, as these skills are highly valued by the Supabase team.
• Be prepared to discuss your vision for how compute and data can be pushed to the edge, and how you can contribute to the evolution of the Edge Runtime.
• Show examples of your work in optimizing latency and reliability in previous roles, and explain how you can apply these skills to the Edge Functions Engineer role.
• Familiarize yourself with the Supabase Edge Runtime and the Deno isolate, and be prepared to ask informed questions during the interview process.
• Consider building a portfolio that showcases your experience with server-side development, Edge Functions, and infrastructure at scale.
• Be prepared to discuss your experience with async communication and remote work, and how you can thrive in a distributed team environment.
