About CircuitHub CircuitHub is reshaping electronics manufacturing with The Grid, a factory-scale robotics platform that makes small-batch, high-mix electronics assembly radically more efficient. Think semiconductor-fab precision applied to the chaotic world of prototyping and low-volume production: a 10x throughput improvement in one of the world's most foundational industries. We've raised $45M from top-tier investors including Plural, Y Combinator and Google Ventures, and we're already profitable. Our customers include a major EV maker, a top AI lab and many of the worlds largest companies. The Grid isn't a prototype. It's live, scaling fast and delivering real revenue, and we're building the team that will scale it further. What you'll do

• Shape the customer experience. Upload, quoting, ordering and our board viewer on circuithub.com.
• Make internal tools a pleasure. Our admin dashboard runs purchasing, planning, recruiting and the AI agents that do more and more of the work. Make dense, data-heavy screens clear and fast.
• Design for the factory floor. Screens operators read at a glance while robots move around them.
• Own the design system. Bring our brand, components and patterns together across web apps and machine screens.
• Design for agents. Work out how people should review, steer and trust the work of AI agents.

What we look for

• You've shipped full-featured web apps in TypeScript and React, and you can show us.
• A real eye for design, both UI and UX. A portfolio we can look at matters more than a job title.
• You enjoy owning a product end to end, from talking to users to deploying.
• You use coding agents to move faster and take full ownership of what they produce.
• Bonus: data visualisation, Elm or other functional languages, industrial or operator interfaces.

Stack

• Web: TypeScript, React, TanStack (Start, Router, Query, Table), Tailwind, Radix, Bun
