About the role
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)
