Job description

The Opportunity

UserWise is looking for an experienced Lead UI/UX Designer to own the UI/UX discipline for a a mobile Free-to-Play game based on a globally recognized entertainment IP.

This is a hands-on leadership role for someone who can translate game and product designs into clear flows, wireframes, and interactive prototypes before significant art or engineering work begins. You will stay ahead of production, validate interactions early, identify usability problems before they become expensive production problems, and follow features through implementation to ensure the intended player experience survives into the final game.

You will also mentor and work alongside an existing UI/UX Designer, helping establish stronger UX processes, patterns, and quality standards across the project.

This is not a management-only role. We are looking for someone who is comfortable getting directly into the work — mapping flows, wireframing screens, building prototypes, iterating on UI, reviewing builds, and solving problems alongside Game Design, Art, Product, Engineering, and Production.

What You’ll Do

• Own the overall UX quality and UI/UX discipline across the game.
• Translate game and product concepts into clear user journeys, flows, wireframes, and interactive prototypes.
• Stay ahead of production by resolving major interaction and usability questions before features move into Art and Engineering.
• Rapidly prototype and compare UX solutions before committing significant production time.
• Own information architecture, navigation, screen hierarchy, interaction patterns, usability, and player comprehension.
• Design intuitive experiences for gameplay, progression, onboarding, rewards, LiveOps, social features, and monetization.
• Proactively identify UX problems through design reviews, prototypes, and playable builds.
• Follow features through implementation and work with Engineering to preserve design intent.
• Improve the Game Design UX Art Engineering workflow so features move through production with clearer intent and fewer late-stage redesigns.
• Establish reusable UX patterns, UI components, interaction standards, and documentation.
• Mentor and work in parallel with another UI/UX Designer while remaining directly involved in execution.
• Partner closely with the Art Director to define and evolve the visual language of the UI, translating the game’s overall art direction into a cohesive, scalable interface system.

What We’re Looking For

• Senior or Lead-level experience designing UI/UX for shipped games.
• Strong shipped experience with mobile Free-to-Play games, ideally casual or mass-market titles.
• A portfolio demonstrating both UX thinking and finished game experiences, not just polished UI screens.
• Strong ability to turn complex game systems into simple, intuitive player experiences.
• Excellent understanding of mobile interaction design, information architecture, hierarchy, readability, feedback, and usability.
• Experience designing F2P systems such as progression, rewards, FTUE, events, LiveOps, and monetization.
• Strong wireframing and interactive prototyping skills.
• Strong proficiency with Figma or equivalent modern product-design tools.
• Strong UI design fundamentals and the ability to take work beyond low-fidelity UX when needed.
• Strong product judgment and a proactive approach to identifying and solving experience problems.
• Experience mentoring or providing design direction to other UI/UX Designers.
• Experience collaborating closely with Game Designers, Artists, Engineers, Product Managers, and Producers throughout feature development.
• Familiarity with Unity-based game production is highly valuable.
• Comfort using AI-assisted or rapid-prototyping tools to explore and validate design solutions faster is a plus.

Portfolio

A strong portfolio is essential for this role.

We are particularly interested in examples that demonstrate:

• Shipped mobile and F2P game experiences
• User flows, wireframes, and interactive prototypes
• Evolution from early UX concepts to final shipped UI
• Gameplay, onboarding, progression, rewards, LiveOps, or monetization UX
• Examples where you simplified a complex feature or solved a meaningful usability problem
• Your individual contribution versus the work of the broader team

Case studies showing how you arrived at a solution are especially valuable. We want to understand the problem, the alternatives you explored, the decisions you made, and how the experience evolved through implementation.

Why Join UserWise

• Own the UX of a flagship mobile game based on a globally recognized entertainment IP.
• Have significant influence over the product while it is still actively being shaped.
• Work in a lean team where UI/UX is central to the game experience rather than a downstream production function.
• Establish the UX processes, standards, and design systems that guide the project.
• Experiment with rapid prototyping and AI-assisted workflows to increase iteration speed and design quality.
• 100% remote, flexible work with a small, experienced team.
