UI/UX Designer

About Rezzil

Rezzil creates performance products across B2B, B2C and gaming, bringing together sport, data and immersive technology across VR, mobile and console. Our products are used by athletes, teams, players and fans, with experiences ranging from elite sports performance tools through to consumer games and connected applications.

We are based in Manchester and London, with flexible and hybrid working options depending on the role and business needs.

The opportunity

We’re looking for a mid to senior-level UI/UX Designer to join the Rezzil team and help shape the user experience across our games and performance applications.

This role sits at the intersection of product design, game design and implementation. You’ll work closely with our design, art, game design and development teams to take UI designs from Figma into Unity, ensuring they are not only functional and accurate, but polished, responsive and engaging in the final product.

You’ll play a key role in setting the stage for how players and users move through our games and apps, from onboarding and navigation through to in-game feedback, menus, progression systems, performance dashboards and interaction flows.

This is a hands-on role for someone who understands great visual design, but also knows how UI behaves inside a real-time product. Unity experience is essential, as you’ll be expected to implement, refine and elevate UI directly in-engine.

What you’ll do

• Design and implement UI and UX across Rezzil’s games, performance applications and interactive products.
• Take designs from Figma into Unity and build polished, production-ready UI screens, flows and components.
• Add motion, transitions, feedback and visual polish to make interfaces feel responsive, intuitive and engaging.
• Work closely with game designers to define player journeys, interaction flows, menu structures and in-game user experience.
• Collaborate with artists, developers and product stakeholders to ensure UI supports both the creative vision and product goals.
• Create wireframes, prototypes, user flows and interface layouts for new features and products.
• Translate UX requirements into clear, usable and visually consistent in-engine experiences.
• Help maintain and evolve UI systems, design patterns and component libraries across products.
• Consider usability, accessibility, platform requirements and player expectations when designing interfaces.
• Support testing and iteration by reviewing feedback, identifying friction points and improving the user experience.
• Work across a mix of sports, gaming and performance-focused products across mobile, VR, console and related platforms.

What we’re looking for

• Proven experience as a UI Designer, UX Designer, UI/UX Designer, Product Designer or similar role within games, apps, interactive media or real-time products.
• Strong hands-on experience implementing UI in Unity.
• Confident working from Figma designs and translating them into polished in-engine interfaces.
• A strong portfolio showing UI design, UX thinking and final product implementation.
• Good understanding of player experience, interaction design, user flows and usability principles.
• Ability to add visual flair through animation, transitions, feedback states and micro-interactions.
• Strong understanding of layout, typography, hierarchy, colour, iconography and visual consistency.
• Experience working closely with game designers, artists and developers.
• Comfortable taking a feature from concept or wireframe through to final in-engine implementation.
• Ability to balance creative design with technical constraints and performance considerations.
• Good communication skills and the ability to explain design decisions clearly.
• Comfortable working across multiple products and adapting design thinking to different audiences, platforms and use cases.

Bonus points for

• Experience working in Unreal Engine.
• Experience designing UI for sports games, fitness products, performance tools or data-led applications.
• Experience with mobile game UI, console UI, VR interfaces or cross-platform design.
• Knowledge of Unity UI systems, animation tools, prefabs, UI optimisation and responsive layouts.
• Experience creating or maintaining design systems.
• Motion design experience, particularly for game UI, onboarding, transitions or feedback states.
• Understanding of accessibility best practice in games or interactive products.
• Experience working with live products and iterating based on player behaviour, feedback or analytics.

The kind of person we think will do well

You’ll likely be someone who enjoys both designing and making. You care about how something looks, but also how it feels in the hands of the player or user.

You’ll be comfortable collaborating with designers and developers, but also confident enough to take ownership of UI implementation and push the final result beyond a flat design. You’ll understand that good UI in games and apps is not just about screens, it is about clarity, flow, feedback, timing and how the experience supports the player.

This role would suit someone who has already built strong UI/UX foundations and is ready to take real ownership across a range of ambitious sports, gaming and performance products.

What we offer

• Competitive salary + share options.
• 25 days’ holiday + bank holidays.
• Christmas closure (3 additional days).
• Flexible working and hybrid options.
