Ideal candidate

A craft-obsessed design engineer who loves owning systems end-to-end and sweating micro-interactions. You care about accessible, consistent UI and raising the bar for how teams ship product.

Requirements

• 4-8+ years building production frontends with TypeScript and React, with track record owning a system, platform, or surface end-to-end
• Solid instincts for animation principles including easing curves, choreography, anticipation, follow-through, interruptibility, and perceived performance
• Fluency in Figma at expert level — auto-layout, variants, variables, and code connect — and proficiency with framer-motion, gsap, and lottie
• Demonstrable obsession with craft, backed by portfolio, side projects, GitHub, or production work including systems-level work
• Experience driving adoption of a design system or shared platform across an engineering org and influencing technical or design direction
• Experience with AI product surfaces — tool-call UIs, streaming responses, agent state, and dynamic UI rendering
• Comfort navigating ambiguous, cross-team problems with good judgment about when to loop others in
• Commitment to WRITER's values of Connect, Challenge, and Own
