Senior Backend Performance Engineer - Node.js (Europe)
TypeFull-time job
LocationUnited States
Posted1 day ago
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)
