Role Summary

We’re building a small, senior team to create exceptional real-time, web-first interactive experiences across our portfolio. Work that pushes what WebGL can do and sets the bar for high-craft fan engagement. We blend the creative sensibility of top interactive studios with the technical ambition of game development, and we’re hiring the founding members who will shape everything that follows.

This is a foundational hire. You’ll define the technical patterns, systems, and standards this team builds on.

You think in systems but care deeply about the end result. As comfortable discussing feel and feedback as render pipelines. You’ve shipped impressive work and know how to build foundations that scale from bespoke interactive pieces to full real-time applications and games.

What you’ll do

  • Architect the core WebGL rendering platform for a growing suite of interactive experiences
  • Own the systems layer: scene management, asset loading/streaming, input handling, state machines, game-loop architecture, camera systems, transition infrastructure, and complex interactive sequencing
  • Write custom GLSL shaders with creative technologists, pushing beyond out-of-the-box capability
  • Define technical patterns, tooling, performance standards, and documentation that help the team move fast within shared engineering practices, code review, release processes, and systems owned by other teams
  • Own performance as a creative constraint: GPU budgeting, profiling, draw-call management, and cross-device optimisation
  • Partner with Creative, Product, Engineering, Platform, Mobile, QA, Analytics, and other stakeholders to turn ambitious concepts into polished, performant, production-ready experiences
  • Help shape the team as it grows, with a clear path toward technical leadership

Basic Qualifications

  • Deep understanding of browser-based real-time rendering and game runtime primitives, not just tools like Babylon.js or Three.js, but what’s underneath: HTML canvas, WebGL/WebGL2, render loops, game loops, scene graphs, cameras, transforms, shaders, textures, buffers, draw calls, input handling, GPU/memory constraints, and browser performance tradeoffs
  • Fluency in GLSL concepts and shader debugging, with enough depth to support renderer architecture, performance, and creative technologist workflows
  • Expert TypeScript/modern JavaScript skills with a track record of well-structured, scalable codebases
  • Experience with entity-component or similar compositional architectures, game-loop patterns, and state management systems
  • An instinct for building extensible foundations other developers can build on
  • Experience in modern frontend ecosystems: shared packages/libraries, asset pipelines, API integration, performance profiling, and mobile web/WebView constraints
  • Leadership experience and communication skills to set direction for a growing team
  • A portfolio showing both technical rigour and genuine creative ambition
  • A track record of shipping interactive work to public audiences where quality of experience was the measure of success
  • Comfort translating ambiguous visual and experiential goals into concrete technical plans without needing everything specified upfront

Preferred Qualifications

  • Game development background (highly preferred)
  • Familiarity with animation/interaction libraries (e.g. GSAP) or physics libraries
  • Experience building and documenting shared developer tooling, SDKs, or internal frameworks
