Job description

Build the interface engineers actually debug production in, from trace waterfalls to live-streaming views. What you’ll work on • Build the interface engineers actually debug production in: dashboards, trace waterfalls, flamegraphs, live-streaming views. • Own features end to end, from data-fetch through interaction design to ship. What we look for • Deep React fundamentals, not just the API but how rendering, state and reconciliation actually behave. • Strong TypeScript and a real feel for state management in complex, stateful apps. • Hands-on builders with a strong sense of ownership: self-starting, fast-moving, unblocked. • Engineers who genuinely want to do UI work and care how it feels to use. • People who thrive in a startup: short feedback loops, direct contact with customers. Bonus • Data-visualisation or charting at scale: canvas rendering, virtualisation, streaming updates. • Experience with observability or developer tooling, as a builder or as a user. • Full-stack reach into the API layer. How we work • Small team, short feedback loops, real ownership from week one. • You’ll talk to customers, engineers debugging real incidents, and that shapes what you build. • We ship, then iterate; bias toward hands-on building over process. • Modern tooling is encouraged, including AI-assisted development.
