Please note that this is a hybrid position based in Brighton, requiring 3 days onsite each week, with the option for remote work on the remaining days.

Atomic Theory is a multinational team of seasoned AAA veterans with roots at studios like Blizzard, PUBG, Epic Games, and Unity. We’re passionate about building player-first experiences with strong engineering foundations, performance excellence, and accessibility baked in from day one.

With offices in Albany, NY; Austin, TX; Cardiff, UK; and Brighton, UK, we operate globally with one mindset: Get Sh!t Done.

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.

• Clear communication skills, including the ability to flag blockers and propose practical solutions.

• Strong grasp of UI/UX fundamentals, usability, readability, and accessibility.

• Passion for polished, performant, and intuitive player experiences.

WHAT YOU MAY ALSO HAVE:

• Experience with dynamic HUDs, procedural UI, or live-service UI elements.

• Familiarity with UI middleware or advanced engine pipelines.

• Experience building shader-based UI, advanced materials, or complex animations.

• Exposure to UX metrics, usability testing, or iterative optimisation.

WHAT WE CAN OFFER:

Competitive Salary and Benefits Package: Your health and wellbeing is important to us, so we offer a variety of benefits including:

• Hybrid Working Arrangement: Our office in Brighton is located centrally. As a member of our team, you’ll have the flexibility to work at home and collaborate with your fellow team members in person.

• Annual Leave, plus Bank Holidays and Winter Break Office Closure

• Annual Research Credit: We always encourage personal growth, so we provide all of our team members with an annual credit to further enhance your skills!

• Work-Life Balance: We really believe that home life comes first and we promote a flexible working environment. And as an added bonus: We don’t crunch!

• Family Friendly: We understand the importance of family, which is why we offer 6 weeks full of Maternity, Paternity, and Adoption Leave to support you during this exciting time!
