Motion Designer (UX/Interface)

The role

You will design motion and animation for AI product interfaces. This includes creating motion for loading states, streaming responses, task progress, and system transitions to help users understand system state.

What you will do

• Design motion and animation for AI product interfaces, including loading states, streaming responses, task progress, and system transitions.
• Create motion that helps users understand what the AI is doing without requiring them to read long explanations.
• Develop animation patterns for uncertainty, thinking states, waiting states, failure, recovery, and asynchronous AI processes.
• Work with product and UX designers to define how motion supports feedback, confidence cues, and error states.
• Build motion specs and prototypes that engineers can implement accurately.
• Define and maintain motion design principles and a reusable animation library for AI surfaces.
• Ensure motion performance is appropriate for real-time and latency-sensitive AI interactions.
• Use motion to reduce confusion, not add decoration.

Required qualifications

• Experience in motion design for digital products, with a portfolio showing interface animation.
• Proficiency in After Effects, Lottie, Rive, or equivalent tools.
• Understanding of how motion communicates system state, feedback, progress, and user guidance.
• Ability to design animation that works within technical constraints of mobile and web.
• Experience working closely with product designers and engineers.
• Awareness of accessibility and performance considerations for animation.
• Good judgment on when motion helps users and when it creates noise.
• Curiosity about how motion can communicate AI behavior, trust signals, and uncertainty.

Before you apply

• Candidates are expected to submit a portfolio as part of the application process.
• If there appears to be a fit, there will be 2 rounds of interviews and a design assessment.
