Responsibilities
- Own user-facing features (advanced search, model usage dashboards, sync-rule management, interactive content previews) and sweat the details that make them feel effortless
- Reach for the right tool for each problem: native HTML elements and modern CSS where they do the job well, React where it earns its place
- Treat performance and accessibility as first-class outcomes, not afterthoughts: quick on a mid-range device and a flaky connection, usable with a keyboard and a screen reader
- Build and maintain shared component libraries and a frontend architecture
- Tackle real frontend challenges: complex state, large datasets, keeping the UI fast and responsive across the app
- Work closely with designers, engineers and Revit experts
Requirements
- A deep, hands-on command of HTML and CSS: semantics, layout, and modern CSS (cascade layers, container queries, :has(), logical properties, oklch(), whatever the job needs), plus an eye for spacing, states, and the details that make an interface just work
- Fluency in JavaScript/TypeScript and React, comfortable in a modern component-based codebase and able to tell when a problem needs JavaScript at all
- A habit of progressive enhancement: build something that works, then layer on the nice-to-haves, so a slow network or an old device degrades gracefully instead of breaking
- Hands-on in the browser's DevTools as a real debugging instrument, not just a place to dump console.logs. You can use the Performance panel to find what's blocking the main thread, read a network waterfall, throttle CPU and network to reproduce a user's bad day, and inspect the DOM and computed styles to track down a layout bug
- Several years (think 5+) building real things for the web, and experience reasoning about complex UI systems and state across a real app
- A strong eye for design and interaction, and a real appreciation for good UX
- You question your defaults and don't pull in a library or reach for a framework feature just because it's there, and you can explain the calls you made
Nice to Have
- Web-performance chops (Core Web Vitals, real-user vs. lab data, the cost of JavaScript on low-end devices)
- Accessibility experience (WCAG, testing with a screen reader)
- Familiarity with the modern frontend ecosystem (Tailwind, Zustand, Radix, Framer Motion); useful, never the point
- Experience with Revit, 3D, or AEC tools
Benefits
- Competitive salary
- A beautiful, plant-filled office in central London (by Southwark tube station) and good coffee (obviously)
- A no-BS team of people who love building good software together
- Real autonomy and influence over product and tech decisions
- A company that believes in work-life balance

How we think about the web
We get excited about what the browser can already do. We'd rather use a view transition in a few lines of CSS than ship a single-page app to fake one. We think doing less work is usually faster than doing more, that every layer of abstraction is something you then have to maintain, and that the platform (versionless, resilient, quietly getting better while you sleep) is the safest thing to build on. So we care a lot about fundamentals: progressive enhancement, semantic HTML, modern CSS done properly, accessibility that's built in rather than bolted on, and a healthy skepticism toward complexity for its own sake. We use React because it earns its place in our product, not because it's the default, and not as a substitute for understanding the platform beneath it. If that resonates, you'll fit right in.
You’re probably someone who
- Is first and foremost a builder, and cares about the outcome as much as the ship date - Reaches for the simplest thing that works - Likes being in the room where product decisions happen - Loves shipping quickly and often, in person, with a small, motivated team - Is curious about how the web works under the hood, and keeps learning - Values calm focus, thoughtful collaboration, and a real sense of craft
