Mob Entertainment is seeking a Technical UI Designer with strong expertise in Unreal Engine and to join our team on a contract basis for our next release. This role is ideal for a mid-to-senior-level designer or technical designer who can own the technical implementation of animated and interactive UI systems—ensuring that everything from HUDs to menus to in-world overlays work smoothly, look great, and are performant under the hood.

This position sits at the intersection of design, animation, and engineering, with a heavy emphasis on using UMG and Blueprints. You’ll be responsible for making sure UI functions as intended, is efficiently implemented, and is tightly synced with gameplay logic, inputs and more.

• Implement static and animated user interfaces that are easy to understand, easy to navigate, and convey information for effective end user experience.
• Execute UI design in engine with a keen eye for detail at all levels – keeping in mind the overall art treatment, screen-to-screen- UI placement, and data structures, while applying and maintaining consistency throughout the entire project interface.
• Implement and maintain Enhanced Input compatibility for UI navigation across keyboard, mouse, and gamepad.
• Collaborate with UI/UX Designers and UI Artists to bring interactive UI animations to life in a way that is responsive, performant, and gameplay-aware.
• Optimize UI systems for draw calls, tick rate, animation memory, and runtime performance across platforms.
• Document implementation standards for UI and support other team members in integrating or extending systems as needed.
  

• Proficiency in Unreal Engine, with experience working directly in UMG, Blueprints, and Enhanced Input.
• Experience implementing animated, responsive UI components that react to gameplay events, player input, and internal UI states.
• Working knowledge of performance bottlenecks specific to UI (tick cost, render layering, CPU/GPU overhead).
• Experience building and managing data-driven UI components, including health bars, popups, action prompts, and animated HUDs.
• Solid understanding of UI architecture, lifecycle events, and state management in Unreal Engine.
• Comfortable collaborating with designers and animators to translate visual ideas into engine-ready technical solutions.
• Strong documentation and debugging skills; able to diagnose both visual and logic-related UI issues.
  

• Familiarity with retro or pixel-art UI integration, particularly when combining animated overlays with clean player feedback.
• Knowledge of procedural or systemic UI generation, especially when paired with animated feedback.
• Familiarity with motion design principles for game-centric UI/UX.
• Programming experience (C++, C#, etc.)
  

• Deliver polished, responsive, and stable UI systems that meet gameplay needs and technical constraints.
• Build a scalable and maintainable UI pipeline that other team members can follow.
• Maintain visual consistency, performance standards, and systemic flexibility across all UI components.
• Collaborate cross-discipline to ensure that UI behavior matches the game’s tone, pacing, and player expectations.
  

• Reports to: Game Director, UI Lead & Engineering Lead
• Works closely with: UI/UX Designers, Animators, Gameplay Engineers, and Technical Designers
• Communication Tools: Unreal Engine, Slack, Jira, Confluence, Figma
