ABOUT THE ROLE

As an Mid-Level UI/UX Designer, you are a fully capable, independent contributor who handles complex UI tasks and systems within your domain.

You take ownership of mid-scope UI features and solve complex design or technical challenges. You are expected to work autonomously, unblock peers when necessary, and ensure your work is high-quality, stable, and integrated into the project pipeline.

At this level, you are not leading the team, but you are a key contributor whose technical and design expertise keeps features moving forward efficiently.

WHAT YOU'LL DO

• Design, implement, and optimise complex UI features and systems (menus, HUD modules, dynamic flows, procedural elements).
• Develop and maintain UI libraries, reusable components, and critical systems to support your feature domain.
• Implement and optimise or have knowledge of custom UI shaders, materials, or advanced animations to achieve specific visual or functional goals.
• Debug and solve technical UI issues (engine, blueprint, middleware) to unblock your feature work.
• Validate UI functionality and appearance across resolutions, aspect ratios, and gameplay contexts.
• Improve personal and small-team workflows to increase efficiency and reliability.
• Contribute to UX flows, usability, and interface consistency within your domain.
• Maintain documentation for tools, systems, and components to ensure clarity and reproducibility.
• Collaborate with engineers, designers, and producers to integrate features smoothly.

WHAT WE VALUE:

• 3+ years of experience in UI/UX design (games or interactive products).
• Proven ability to deliver mid-scope UI features independently, including complex interactions or procedural systems.
• Proficiency with design tools (Figma, Photoshop, Illustrator) and engine implementation (Unreal, Unity).
• Strong understanding of UI technical fundamentals, including layout, anchoring, slicing, optimisation, and Blueprint/scripting basics.
• Ability to debug and resolve complex technical and design challenges within your feature domain.
• Experience developing or optimising UI systems or libraries that improve efficiency and consistency.
