The posting

We're hiring an engineer to build the backend infrastructure behind an exceptionally fast product — one that stays fast regardless of scale. The system is live and growing; your job is to drive latency down across every layer of the stack.

This is a high-ownership role: you'll own backend performance across the platform and build custom infrastructure wherever off-the-shelf solutions can't keep up.

What You'll Do

  • Own backend performance across the platform — databases, APIs, queues, and background processing
  • Design advanced caching and data synchronization systems
  • Profile production systems and eliminate latency bottlenecks at every layer
  • Build custom infrastructure where third-party solutions aren't fast enough
  • Improve scalability while keeping response times low
  • Work with feature teams to hit performance targets, and continuously benchmark against best-in-class SaaS products

What We're Looking For

Must have:

  • 4+ years of backend engineering experience, including 4+ years building and scaling high-traffic production systems
  • Proven track record of optimizing large-scale backend systems
  • Deep expertise in Node.js, TypeScript, PostgreSQL, Redis, networking, and distributed systems
  • Extensive experience with database optimization, caching, asynchronous processing, and API performance
  • Experience building custom infrastructure instead of relying solely on third-party solutions
  • Strong computer science fundamentals, algorithms, and systems design knowledge; exceptional engineering standards and attention to detail
  • Experience building products where latency and scalability were critical to the business

Nice to have:

  • Experience with high-volume messaging or event-driven systems
  • Experience at a startup or fast-moving product company
  • Familiarity with performance observability tooling (profilers, tracing, APM)

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
