性能工程师 - 性能分析与调优
Performance Engineer - Performance Analysis & Tuning
关于 Supabase
Supabase 是基于 Postgres 的开发平台，由开发者为开发者打造。我们提供完整的后端解决方案，包括数据库、认证、存储、边缘函数、实时功能和向量搜索。所有服务深度集成，专为增长而设计。
关于该职位
我们正在招聘经验丰富的性能工程师，在 Supabase 技术栈中发现并实现性能提升——从查询优化器到块设备级别，以及连接我们分布式平台的网络路径和云基础设施。这是一项性能交付工作：在我们向企业级和平台级工作负载扩展时，对我们的数据库、平台和 API 实现真实、可衡量的改进。你所开发的方法和构建的工具旨在放大这种交付效果。
你将作为团队的首批成员之一加入一个新的性能团队，与一位经验丰富的性能工程师一起工作，今年团队将扩大到约六人。你不需要继承任何遗留流程——你将帮助定义 Supabase 的性能工程方式。
你将负责的工作
- 在生产系统中发现瓶颈，并精确地进行表征，使相关团队能够在没有你的情况下采取行动。
- 与数据库团队（如 Multigres、OrioleDB）和基础设施团队紧密合作，实现具体的性能改进。
- 构建、沟通并持续改进性能方法和工具，将生产环境数据转化为可操作的洞察。
- 与可观测性团队合作，捕获正确的信号，建立统一的平台性能视图（延迟、吞吐量、尾部行为）跨产品。
- 帮助团队自助进行性能分析，让性能成为工程的核心关注点。
你可能遇到的问题
- 调整内核的分页行为以适应生产工作负载
- 降低 OrioleDB 和 Multigres 中的内存开销
- 从应用层到内核层识别并消除延迟峰值的来源
- 识别整个技术栈中的可扩展性瓶颈，并与 Supabase 内部团队及更广泛的社区合作解决这些问题
我们寻找的人选
- 在性能工程方面有深入经验，特别是对复杂分布式系统的性能分析。
- 你可以全程跟踪问题：从查询优化器开始，沿着系统调用边界到 IO 调度器——或者跨连接池跳转、网络路径和可用区，阅读性能剖析数据。

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.
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. 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.
ABOUT THE TEAM
Supabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love.
- ~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. If it’s in your project, we probably use it in ours too. We believe deeply in the open-source ecosystem and strive to support—not replace—existing tools and communities.
