# Performance Engineer - Performance Analysis & Tuning **Company**: Supabase **Location**: Remote, Global **Work arrangement**: remote **Experience**: senior **Job type**: Full time **Category**: Engineering **Industry**: Technology **Apply**: https://jobs.ashbyhq.com/supabase/98ef6a11-9898-4960-9931-1264285849f3?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply **Canonical**: https://yubhub.co/jobs/job_c5eeda25-147 ## Description 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 delivery 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. 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. ## Responsibilities - Find bottlenecks in live production systems and characterize them precisely enough that the owning team can act on them without you in the room. - Partner closely with database teams (e.g. Multigres, OrioleDB) and infra teams to land concrete performance improvements. - Build, communicate, and evolve performance methodologies and tooling that turn live production data into actionable insight. - Partner with the observability team to capture the right signals and establish a unified view of platform performance (latency, throughput, tail behavior) across products. - Help teams self-serve performance analysis and make performance a first-class engineering concern. ## Problems you might work on - Tune the kernel's paging behavior to production workloads - Reduce memory overhead in OrioleDB and Multigres - Identify and eliminate sources of latency spikes from application to kernel level - Identify scalability bottlenecks across the entire stack and work the appropriate teams in Supabase and the wider community to resolve them ## Requirements - Deep experience in performance engineering, specifically performance analysis of complex distributed systems. - 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. - 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) - 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). - 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. - Strong written communication: your problem characterisations are precise, reproducible, and compelling on their own. - Pragmatic, tooling-oriented mindset; comfort working across product, infra, and database teams. ## Benefits - 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. ## Skills ### Required - performance engineering - distributed systems - Linux kernel internals - database internals - networking - cloud infrastructure --- Source: [Apply at jobs.ashbyhq.com](https://jobs.ashbyhq.com/supabase/98ef6a11-9898-4960-9931-1264285849f3?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply)
