Design Engineer

About the Role

You will own the behavioral layer of product UI: define interaction models, state transitions, and sequencing; design motion systems, easing, and timing; and build high-fidelity, motion-first prototypes in code. You will rapidly explore variants, validate UX decisions with React/Next.js prototypes, and translate behaviors into reusable tokens and component specs. You will collaborate with designers to simplify complexity and with engineers to ensure feasible, performant implementations. You will also design loading and feedback patterns, pressure-test edge states, and raise the interaction quality bar across the product.

Requirements

  • 5+ years in a hybrid design and engineering role
  • Strong GSAP or Framer Motion skills
  • Experience building prototypes in React and Next.js
  • Deep understanding of timing, easing, and motion hierarchy
  • Strong visual craft including spacing and type alignment
  • Knowledge of animation performance and avoiding layout thrash
  • Ability to communicate behavior through prototypes and diagrams
  • High attention to interaction detail and quality

Responsibilities

  • Define interaction models and state diagrams
  • Shape transitions to improve clarity and perceived performance
  • Establish behavioral defaults and consistent interaction patterns
  • Design motion systems and motion tokens
  • Build GSAP and Framer Motion animations
  • Prototype flows in React and Next.js
  • Explore multiple interaction variants quickly
  • Design multi-state component behavior and micro-interactions
  • Shape feedback for transactions, loading, optimistic UI, and errors
  • Develop interaction and motion tokens for reusable primitives
  • Collaborate with design-system and engineering teams
  • Design loading behaviors and diagnose UX friction
