Senior React + Three.js Developer (Interactive Installations)

Type: Permanent or long-term contract (flexible)
Location: London-based role – 3 days in the studio p/week

The studio

The company is a globally recognised creative production studio that builds immersive, interactive experiences for innovation spaces, brand environments, and cultural venues. Owing to a marked increase in projects, the company are seeking an experienced Senior React + Three.js Developer to work on a number of exciting upcoming projects.

What makes this job stand out

• You’ll build things people physically engage with, in real spaces, with real audiences.
• You’ll have proper ownership: take work from concept through build to launch, not just ticket-shuffling.
• The work is varied: interactive 3D, data-driven stories, performance challenges, and the satisfaction of shipping something that has to hold up in the wild.
• You’ll be surrounded by designers and creative technologists who care about craft, not buzzwords.
• You’ll have time to do it properly: performance, stability, and clean architecture matter here because installations punish shortcuts.

The role

As a Senior React + Three.js Developer (Interactive Installations), you’ll be the React + 3D specialist helping to ship installation-grade experiences. That means building beautiful interactive scenes, but also hardening them so they run reliably day after day. The Senior React + Three.js Developer will be central to their approach to real-time 3D delivery across projects.

What you’ll be doing

• Building real-time 3D experiences using React + Three.js
• Using a React-to-Three integration layer like @react-three/fiber (plus the surrounding ecosystem)
• Creating reusable scene/component systems so they can move fast without chaos
• Performance work: profiling, asset optimisation, render budgets, graceful degradation
• Integrating real-world inputs and content updates (data feeds, control layers, CMS-driven content, etc.)
• Supporting installation and commissioning when needed (occasional on-site days)

What they’re looking for (must-haves)

• Strong React experience (TypeScript preferred)
• Solid Three.js experience with proof you’ve shipped interactive 3D (portfolio, demos, videos)
• Real experience with react-three-fiber / @react-three/fiber (or equivalent patterns)
• proficient with managing performance constraints and debugging in real-time rendering
• Practical engineering mindset: you can build fast and build for reliability

Strong bonus points

• Shaders / GLSL, post-processing, lighting and material pipelines
• Experience with kiosk deployments (offline-first, auto-restart, watchdog patterns, “it just runs”)
• Multi-display or large-format screen experience
• Sensors / OSC / websockets / unusual inputs
• Any museum, exhibition, experiential, themed environment, or live events background

This is an exciting opportunity to join a busy company with a solid pipeline of varied, high-profile projects.
