Job description

Crafting fast, focused UIs that make working in Revit actually enjoyable

Hey there — we’re Kinship 👋

We’re building the Revit tools you wish existed. Our platform helps architects and engineers manage content, track usage, and make smarter decisions with less hassle.

We’re looking for a frontend-focused engineer who sweats the details, moves quickly, and loves turning complex workflows into smooth, intuitive experiences. Someone who cares about performance, polish, and pushing things live that users love.

In this role, you will:

• Own the development of new user-facing features — like advanced search tools, model usage dashboards, sync rule management, or interactive content previews

• Work closely with design to craft fast, responsive, accessible interfaces

• Build and maintain shared component libraries and frontend architecture

• Tackle real frontend challenges — like managing complex state, handling large datasets, and keeping the UI fast and responsive across the app

• Collaborate with a tight-knit team of engineers, designers, and Revit pros to bring new ideas to life quickly and iteratively

What We're Looking For

You don’t need to tick every box, but here’s what would help you succeed:

Must-haves

• 5+ years of experience building frontend applications in modern web stacks

• Proficiency with JavaScript/TypeScript and React

• Deep knowledge of HTML and CSS — you care about spacing, states, and making things just work

• Experience building complex UI systems and managing state across large apps

• A strong eye for design and interaction, and a real appreciation for good UX

• Bonus points for experience with Revit, 3D, or AEC tools — or curiosity to learn

Nice-to-haves

• Experience with Tailwind, Zustand, Radix or Jotai

• Experience with Revit, 3D, or AEC tools — or curiosity to learn

You're probably someone who:

• Is first and foremost a builder

• Likes being in the room where product decisions happen

• Loves shipping quickly and often

• Wants to work in person with a small, motivated team

• Enjoys early-stage companies, clear priorities, and wearing a few hats

• Values calm focus, thoughtful collaboration, and a sense of craft

What We Offer

• 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 great software together

• Real autonomy and influence over product and tech decisions

• A company that believes in work-life balance
