What You'll Do

\n

\n

Motion Design:

\n

\n

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

\n

\n

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

\n

\n

Design a cohesive icon set from scratch:

\n

\n

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

\n

\n

Key Deliverables

\n

\n

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

Skills and Experience

\n

\n

Essential:

\n

\n

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

\n

choreography, micro-detail.

\n

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

\n

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

\n

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

\n

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

\n

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

\n

Ability to hand off work cleanly to engineers.

\n

\n

Preferred:

\n

\n

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

\n
