About the Role
We're hiring a design engineer who builds like a founder. You see what's missing and make it exist: you design it, build it, ship it and own it. Code is your design material, and you write a shader when CSS runs out. The bar is an interface that feels physical: it tracks the finger, carries momentum and never drops a frame.
Responsibilities
- Take ideas from a blank file to production: decide what's worth building, prototype it in code, and own it once it ships.
- Build production UI in React and TypeScript, from primitives to complete surfaces.
- Build the custom tools that make the team faster: design-system tooling, motion tuners, debug overlays and internal apps.
- Tune motion and gestures until they feel physical: momentum, weight and interruption.
- Create 3D, shader and generative work where it lifts the experience.
- Review every build on real devices at 1× and 2×, and keep it fast, accessible and robust under abuse.
- Interfaces for streamed, non-deterministic output: progressive rendering, interruption and retry.
- Build daily with AI coding tools such as Claude Code, Cursor or Codex, use them to ship whole tools and products on your own, and review every line they write.
- Work directly with high-pedigree founders shaping technical and product strategy.
- Build infrastructure powering the future of AI compute globally.
Requirements
- 5+ years shipping production front ends, with live work you can link to.
- React and TypeScript at expert level, with component APIs that don't lie: contextual props, derived state, variants over boolean flags and compound components.
- Motion values and direct DOM updates for anything high-frequency, so gestures and scroll never wait on a render.
- CSS in depth: clip-path, masks, backdrop filters, blend modes, scroll-driven animations, container queries and the View Transitions API.
- Type and pixels in code: variable fonts, optical sizing, OpenType features, and layouts free of shift and subpixel blur at 1×, 2× and 3×.
- Performance as a feature: an 8 ms frame budget at 120 Hz, compositor-only animation, and pages that load instantly because every byte was questioned.
- Accessibility as craft: focus rings styled rather than removed, focus moved into overlays and back, full keyboard paths and reduced-motion settings honoured.
- Real-time 3D with Three.js or React Three Fiber on WebGL or WebGPU.
- Shaders in GLSL or WGSL: noise, signed distance fields, glass, refraction, lighting and post-processing, all inside the frame budget.
- Motion studies in After Effects and 3D in Cinema 4D or Blender, so ideas move before a line of production code exists.
- Generative and data-driven work in Canvas and SVG, and interactive animation in Rive.
- Custom tools you built that others rely on: plugins, design and motion tooling, debug overlays, generators or internal apps.
- Something you started and shipped yourself: a product, a studio, a library or a side project with real users/customers.
- Writing and articles about your craft: essays, breakdowns or notes that show how you think.
- Creative coding or generative art.
- Open-source work in motion, graphics or UI components.
