Senior Backend Performance Engineer - Node.js (Europe)

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
