# Performance Engineer

**Company:** [Supabase](https://hotfix.jobs/companies/supabase)
**Location:** Remote
**Role:** Performance Marketing
**Experience:** 7+ years
**Skills:** performance engineering, linux kernel internals, database internals, query optimization, Distributed Systems, Networking, aws infrastructure, Observability, profiling, tracing, performance analysis, tooling development, Postgres
**Posted:** 2026-07-28

> Performance Engineer responsible for identifying bottlenecks across the full stack in Supabase's Postgres platform, from query optimizer to kernel and cloud infrastructure. Requires deep expertise walking the stack on tail-latency issues, Linux or database internals, and driving measured performance wins with cross-team collaboration.

## Job Description

## 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.

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

## What we're looking for
- 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.

## 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.
- 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.
- Flexible Work: We operate asynchronously and trust you to manage your own time.
- Professional Development: Every team member receives an annual education allowance to spend on learning—courses, books, conferences, or anything that supports your growth.
