Performance Engineer - Performance Analysis & Tuning

<h3><strong>About <a href="https://jobicy.com/company/supabase" target="_blank" rel="noopener">Supabase</a></strong></h3> <p>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.</p> <h3>About the Role</h3> <p>We're hiring experienced performance engineers to find and land performance wins across the Supabase stack — from the query optimiser to block device level, and across the network paths and cloud infrastructure that connect our distributed platform. This is a performance <em>delivery</em> role: real, measured improvements to our database, platform, and APIs as we scale toward enterprise and platform-grade workloads. The methodologies you develop and tooling you build exist to multiply that delivery.</p> <p>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 performance engineering works at Supabase.</p> <h3>What you'll do</h3> <ul> <li> <p>Find bottlenecks in live production systems and characterize them precisely enough that the owning team can act on them without you in the room.</p> </li> <li> <p>Partner closely with database teams (e.g. Multigres, OrioleDB) and infra teams to land concrete performance improvements.</p> </li> <li> <p>Build, communicate, and evolve performance methodologies and tooling that turn live production data into actionable insight.</p> </li> <li> <p>Partner with the observability team to capture the right signals and establish a unified view of platform performance (latency, throughput, tail behavior) across products.</p> </li> <li> <p>Help teams self-serve performance analysis and make performance a first-class engineering concern.</p> </li> </ul> <h3>Problems you might work on</h3> <ul> <li> <p>Tune the kernel's paging behavior to production workloads</p> </li> <li> <p>Reduce memory overhead in OrioleDB and Multigres</p> </li> <li> <p>Identify and eliminate sources of latency spikes from application to kernel level</p> </li> <li> <p>Identify scalability bottlenecks across the entire stack and work the appropriate teams in Supabase and the wider community to resolve them</p> </li> </ul> <h3>What we're looking for</h3> <ul> <li> <p>Deep experience in performance engineering, specifically performance analysis of complex distributed systems.</p> </li> <li> <p>You can walk the whole stack: follow a tail-latency problem from the query optimizer through the syscall boundary to the IO scheduler — or across pooler hops, network paths, and availability zones — reading profiles and traces at every layer.</p> </li> <li> <p>Depth on at least one end of that stack: Linux kernel internals (virtual memory, scheduling, networking, IO) <strong>or</strong> database internals (query planning, storage engines, buffer and WAL management)</p> </li> <li> <p>Strong working knowledge of networking and cloud infrastructure performance: TCP behavior under load, network virtualization overhead, and the performance characteristics of AWS primitives (EBS throughput and IOPS, instance network limits, placement groups, cross-AZ latency).</p> </li> <li> <p>Proven ability to turn performance insights into real product and architecture improvements — including getting teams you don't belong to to prioritize and ship the fix.</p> </li> <li> <p>Strong written communication: your problem characterisations are precise, reproducible, and compelling on their own.</p> </li> <li> <p>Pragmatic, tooling-oriented mindset; comfort working across product, infra, and database teams.</p> </li> </ul> <h3><strong>What We Offer</strong></h3> <ul> <li> <p><strong>Fully Remote</strong></p> <p>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.</p> </li> <li> <p><strong>ESOP</strong></p> <p>Every team member receives ESOP (equity ownership) in the company. We want everyone to share in the upside of what we’re building together.</p> </li> <li> <p><strong>Tech Allowance</strong></p> <p>Use this budget to set up your ideal work environment—laptop, monitor, headphones, or whatever helps you do your best work.</p> </li> <li> <p><strong>Health Benefits</strong></p> <p>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.</p> </li> <li> <p><strong>Annual Off-Sites</strong></p> <p>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.</p> </li> <li> <p><strong>Flexible Work</strong></p> <p>We operate asynchronously and trust you to manage your own time. You know what needs to be done and when.</p> </li> <li> <p><strong>Professional Development</strong></p> <p>Every team member receives an annual education allowance to spend on learning—courses, books, conferences, or anything that supports your growth.</p> </li> </ul> <h3><strong>About the Team</strong></h3> <p>Supabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love.</p> <ul> <li> <p>~400 team members</p> </li> <li> <p>60+ countries</p> </li> <li> <p>20+ languages spoken</p> </li> <li> <p>Over $1B raised (including our $500M Series F)</p> </li> <li> <p>540,000+ community members</p> </li> </ul> <p>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.</p>
