Senior Technical UI & Motion Designer

About the role

You will own the end-to-end definition and implementation of UI motion and interaction quality across mobile games, ensuring that every animation, transition, and response feels responsive, polished, and aligned with game feel. You will translate creative design concepts into interactive prototypes and then ship production-ready UI animation systems directly inside Unity. You will partner daily with UI/UX Designers, Game Designers, Engineers, Product, and Art Direction to define interaction intent and solve technical constraints without compromising on motion detail. You will elevate the player experience by focusing on micro-interactions, timing, and feedback that make the interface feel alive and intuitive. You will build reusable animation patterns and components that scale across games, improving consistency and speed for the wider team. You will iterate on designs based on playtest observations and live performance data to refine motion until it feels just right. You will act as the motion and UI implementation expert, bridging the gap between design vision and technical reality in a fast-paced, product-driven environment.

Key facts

What you'll do

• Translate creative UI concepts into interactive prototypes and production-ready Unity implementations.
• Design and implement polished UI animations, transitions, feedback, and interaction states that enhance clarity and delight.
• Rapidly prototype interactions to explore multiple solutions and validate timing, easing, and responsiveness with the team.
• Build performant, reusable UI animation components, systems, and patterns that integrate cleanly with existing game architecture.
• Collaborate closely with UI/UX Designers, Game Designers, Engineers, Product, and Art Direction to align on interaction intent and constraints.
• Refine game feel through precise motion, timing, spacing, and responsiveness that match the design vision and technical reality.
• Optimize animations for performance, memory, and battery usage to ensure a smooth experience across target devices.
• Iterate on designs based on team feedback, playtest results, and live engagement data to continuously improve interaction quality.
• Maintain consistency across the UI ecosystem by establishing standards, guidelines, and component libraries for motion and interaction.
• Champion best practices in motion design and UI implementation, mentoring peers and fostering a culture of polished, thoughtful interfaces.
• Partner with engineering to identify technical opportunities and limitations, turning animation concepts into robust, scalable solutions.
• Contribute to the definition of tools and workflows that streamline the handoff between design and development.
• Evaluate emerging motion techniques and tooling, proposing experiments that push the quality of UI interaction further.
• Act as the primary owner for UI motion quality, ensuring every shipped feature meets the studio's high standards for polish and responsiveness.

Requirements

• Bring 4+ years of hands-on experience in technical UI, UI animation, motion design, or a related role, ideally within mobile games.
• Present a strong portfolio or reel showcasing high-quality UI motion and interaction design that demonstrates timing, easing, and responsiveness.
• Show deep, hands-on experience building and animating UI directly in Unity, with shipped examples of polished interfaces.
• Prove your ability to take an idea from rough prototype to polished, production-ready implementation without losing motion quality.
• Demonstrate a solid understanding of motion and animation fundamentals, including timing, easing, feedback, anticipation, and transitions.
• Highlight familiarity with motion-design tools such as After Effects, Spine, Rive, or equivalent in your workflow.
• Show advanced understanding of Unity UI workflows, layout systems, and technical constraints that affect animation performance.
• Illustrate your capacity to balance visual quality, runtime performance, and maintainability while keeping systems consistent.
• Provide evidence of strong visual-design fundamentals, especially around composition, hierarchy, readability, and clear feedback.
• Prove you can work effectively within cross-functional teams, communicating clearly and aligning on shared goals.
• Show fluency in English, both written and verbal, to collaborate seamlessly with product, design, and engineering colleagues.
• Demonstrate ownership and accountability, taking responsibility for the quality and delivery of your contributions.
• Show resilience and adaptability in a fast-moving, product-driven environment where priorities can shift quickly.
• Bring a proactive mindset, seeking improvements and raising constructive feedback to elevate the team's standards.

Nice to have

• Ability to write or modify scripts for UI animation and interaction to streamline workflows and add interactivity.
• Experience with particles, VFX, shaders, or procedural UI effects that enhance motion without hurting performance.
• Experience shipping or operating mobile games, with lessons learned applied to your design and implementation decisions.
