Job description

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.
