Performance Engineer - Performance Analysis & Tuning

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 THE ROLE 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. WHAT YOU'LL DO - 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.

• 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.

• 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.

• 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.

• ~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.

• Showcase concrete performance improvements you’ve delivered, including tools and metrics used.
• Prepare to discuss kernel or database internals in depth; expect live profiling or trace analysis examples.
• Highlight any open‑source contributions or tooling you built for performance monitoring.
• Emphasize clear written communication by providing a brief write‑up of a past bottleneck you solved.
• Research Supabase’s stack (Postgres, Edge Functions, Vector Search) to speak confidently about integration points.
• When negotiating, factor in the ESOP component and remote stipend as part of total compensation.
• Watch for vague promises about “remote work only”; confirm the co‑working allowance and health coverage details early.
