This role will shape, prototype, document, and refine user experiences across frontend, engagement systems, and in-match gameplay UI. The project is transitioning from pre-production into production. The UI direction is still taking form, and the team may draw on existing design systems where beneficial while also crafting project-specific patterns. The ideal candidate should feel at ease working closely with UI Art, UI Technical Design, Engineering, Gameplay Design, VFX, Sound, and Production.

Responsibilities

Convert product, gameplay, and player needs into structured UX frameworks and interaction patterns
Build and maintain UX flows using tools such as Figma, HTML prototypes, and in-engine mockups where suitable
Formalize designs into prototypes, design documentation, and specifications ready for implementation
Champion mobile-centric UX while keeping the experience enjoyable across every supported platform in the game ecosystem
Establish UX behavior for navigation, input, responsiveness, accessibility considerations, onboarding, engagement loops, gameplay HUD elements, and live-service touchpoints
Coordinate with UI Engineering and UI Technical Design to handle implementation questions and settle edge cases
Engage with VFX and sound stakeholders to make sure interaction feedback, UI motion, and celebratory moments reinforce the intended player experience
Inspect in-engine implementation and offer feedback to safeguard the original UX intent
Contribute to publishing activities, seasonal updates, post-release iteration, and live-service enhancements

Requirements

No less than 5 years of hands-on professional experience in UX design
Minimum of 1 year in a people management or team leadership role, guiding a team of 5 or more FTEs
Strong track record designing UX for games or intricate interactive products

Background designing for multi-platform products, with a strong emphasis on mobile-first experiences
Confident use of Figma for producing UX artifacts and collaborating on design activities
Ability to work productively with UI Art, UI Technical Design, Engineering, Gameplay Design, Production, Sound, and VFX disciplines
Skill in conveying design intent clearly through prototypes, documentation, reviews, and direct collaboration
Comfort operating on projects where visual direction and design systems are still coming together
Solid systems thinking with the capability to build UX that scales across a range of game features and updates
Ability to balance expressive, animated UI with usability, clarity, and responsiveness
Confident English communication at B2 level or above, in both written and spoken forms
