Performance Engineer - Performance Analysis & Tuning

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.

• 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
