What You'll Do

Motion Design:

Define and deliver the motion system for a mobile product experience:

Loading and processing states - how the interface communicates that work is happening.Transitions between contexts - smooth, purposeful movement as users move between tasks.Approval and confirmation choreography - moments where users pause, review, and act.Content appearance - how new information reveals itself on screen.Error and recovery - how the interface communicates problems gracefully.Micro-interactions - the small things: button feedback, expansion, selection, reorder.Iconography:

Design a cohesive icon set from scratch:

Functional icons across multiple capability areas.State indicators - processing, success, failure, pending.Any illustrations for empty states and onboarding. Prototyping and Handoff:High-fidelity motion prototypes that demonstrate timing and feel.Engineer-ready exports.Design system contributions with full usage guidelines and motion tokens.

Key Deliverables

A motion system: principles, tokens, and reference animations.An icon set covering all functional areas and states.Motion prototypes for core user flows.Exported assets and developer handoff documentation.

Skills and Experience

Essential:

A portfolio that demonstrates craft in interaction and motion design for mobile - timing,

choreography, micro-detail.

Deep expertise in motion principles: easing, duration, sequencing, and how motion communicates state.

Experience designing icon systems with consistent weight, grid, and visual language.

Proficiency in Figma and a motion tool (After Effects + Lottie, Principle, Rive, or similar).

Experience contributing to a design system with motion and component specs.

Understanding of motion accessibility (prefers-reduced-motion, WCAG guidelines).

Ability to hand off work cleanly to engineers.

Preferred:

Experience with card-based or flowing interfaces (messaging, support, or similar patterns).Familiarity with designing for dynamically generated content and real-time interactions.Experience in trust-sensitive domains (financial services, health, government).Understanding of Lottie workflows and mobile animation performance.React Native awareness is a plus.
