Performance Engineer - Performance Analysis & Tuning

About this role

Supabase is hiring experienced performance engineers to identify and implement performance improvements across its distributed stack, from the query optimiser to kernel and network layers. This is a performance delivery role focused on measurable gains to the database, platform, and APIs as the company scales. The role involves joining a new performance team and helping define how performance engineering works at Supabase. Candidates will work with database and infrastructure teams, develop methodologies and tooling, and partner with observability to provide a unified view of platform performance. The position is fully remote with global hiring, and the team emphasises practical impact and cross-team collaboration.

What you would do

• Identify bottlenecks in live production systems and characterise them for owning teams to act on without ongoing involvement.
• Collaborate with database and infra teams to implement concrete performance improvements.
• Develop, communicate, and evolve performance methodologies and tooling based on production data.
• Work with the observability team to capture signals and create a unified view of performance across products.
• Help teams self-serve performance analysis and prioritise performance as a core engineering concern.

What they are asking for

• Deep experience in performance engineering for complex distributed systems.
• Ability to trace performance issues across the stack from query planning to IO and network paths.
• Expertise in Linux kernel internals or database internals with strong depth in at least one area.
• Strong knowledge of networking and cloud infrastructure performance, including TCP, AWS primitives, and cross-AZ latency.
• Proven ability to translate performance insights into product and architectural improvements and prioritise fixes across teams.
• Clear, precise written communication describing problem characterisations and reproducible results.
• Pragmatic, tooling-oriented mindset with experience working across product, infra, and database teams.
