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.

Responsibilities

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.

Requirements

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.

Pluses

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.)

Performance Expectations

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.

Reporting & Oversight
