Design Engineer (Front End & Experiential Web)

We're assisting a well-established startup with their search for a design engineer. Their products are AI creative tools that shorten the distance between concepts and creation. The role will work in the SF office 4 days a week and 1 day remotely.

What you'll do:

40%

Prototype the unheard‑of : Turn Figma frames, motion studies, or half‑sketched ideas into live demos within hours. Throw them away, refine, or harden whatever best answers the design question.

40%

Build & ship user‑facing features:

Craft high‑performance TypeScript/React views and canvases. Polish micro‑interactions, motion, and accessibility until they “disappear” into the experience.

15%

Evolve the design system:

Extend the component library, tokens, and animation primitives so the whole team moves fast and coherently.

5%

Design partnership:

Sit in crits, run designer play‑tests, and surface interaction insights that reshape the roadmap.

What you'll bring:

2+ years of experience in design engineering

Write TypeScript like a first language and have shipped complex SPAs (React, Solid, or similar) to production without losing pixel fidelity

Startup experience

Nice to haves:

Knowledge of CNC / CAD / CAM pipelines or an industrial‑design background

Familiarity with Three.js, React‑Three‑Fiber, or Babylon.js.

Experience bridging ML outputs into interactive UIs
