Performance Engineer - Benchmarking

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 this role We’re hiring experienced performance engineers to make performance measurement at Supabase rigorous, repeatable, and actionable by product teams. This role owns the benchmarking and profiling systems we use to detect regressions, explain performance changes, and publish credible numbers for customers and the market. You’ll build the tooling and the methodology and make it easy for product teams to use it correctly. You’d join a new performance team as one of its first members, working alongside a deeply seasoned performance engineer, with the team growing to roughly six this year. There’s no legacy process to inherit — you’ll help define how we measure and communicate performance metrics at Supabase. What you’ll do • Build and evolve benchmarking, profiling, and load-testing tooling (cloud, database, and end-to-end). • Define benchmark suites and reference workloads that reflect real customer behavior (and evolve them as the products change). • Establish performance baselines and regression gates across products (variance tracking, environment control, and detection of changes). • Build mechanisms that turn benchmark results into action: triage workflows, owner routing, and clear, reproducible reports. • Partner closely with database teams (e.g. Multigres, OrioleDB) to identify bottlenecks and land concrete performance improvements. • Enable the company to publish credible, repeatable performance numbers for customers and the market. • Help teams self-serve performance testing and make performance a first-class engineering concern. Problems you might work on • Build our continuous benchmarking infrastructure so product teams can spot performance regressions early. Ideally, teams can run benchmarks directly on PRs or locally while developing a feature. • Analyze and eliminate issues with load generators, workloads or benchmark environments to ensure that benchmarks are reliable indicators for actual product performance. • Build regression triage tooling that pinpoints what changed (diffing, profiles/traces, query-level attribution). • Help product teams so they can analyze the root cause of performance regressions in benchmark environments themselves. What we’re looking for • Deep experience in performance engineering, benchmarking, and profiling of complex distributed systems. Specifically, you have owned benchmarking systems where reproducibility and controlling variance mattered. • Strong systems intuition (databases, storage, networking, cloud infrastructure). • Comfortable working across product, infra, and database teams. • Pragmatic, tooling-oriented mindset with strong communication skills. • Depth on at least one end of that stack: Linux kernel internals (virtual memory, scheduling, networking, IO) or database internals (query planning, storage engines, buffer and WAL management) 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.
