Senior UI Engineer

Companion Group is a AAA co-development gaming studio with a globally distributed and fully remote setup, renowned for its adeptness in overcoming the most intricate challenges in multiplayer game development.

Embedded seamlessly within a client's in-house team, we collaborate harmoniously to turn dreams into reality. Our portfolio boasts groundbreaking games developed in collaboration with major studios worldwide. As a fully remote studio with colleagues across the globe, we value and emphasise clear, continuous, and transparent communication as highly as technical skills.

As a Senior UI Engineer , you will be at the heart of shaping how players interact with massive, complex multiplayer worlds. You will bridge the gap between design, art, and code, architecting scalable, high-performance user interfaces and HUD systems. Working closely with cross-functional teams, you will ensure that menus, inventory systems, and real-time data visualization remain fluid, intuitive, and perfectly synchronized in a fast-paced networked environment. Your expertise will drive the frontend tech stack, ensuring players enjoy a flawless and immersive user experience.

• Architect & Implement: Design, develop, and refine scalable, modular, and performance-driven UI/UX frameworks both within and outside of Unreal Engine.

• Write Clean Code: Produce elegant, efficient, and highly maintainable C++ and UI scripting code.

• Optimise Performance: Diagnose and resolve UI-related performance bottlenecks (draw calls, memory usage, widget ticking) to maintain high frame rates across PC and consoles.

• Collaborate: Partner closely with UI/UX designers, technical artists, and core gameplay engineers to translate wireframes and visual concepts into responsive, functional in-game systems.

• Multiplayer Integration: Seamlessly connect UI systems with complex multiplayer game states, ensuring accurate, lag-compensated data replication (e.g., inventory updates, matchmaking screens, scoreboards).

• Problem Solve: Tackle and resolve intricate technical hurdles related to localisation, accessibility, cross-platform input systems (controller/mouse/keyboard), and aspect ratio scaling.
  

Qualifications & Technical Skills

• Experience: 6+ years of professional game development experience, with a heavy focus on UI engineering.

• Engine Expertise: 4+ years of deep experience working with Unreal Engine UI frameworks (UMG, Slate, CommonUI).

• Proprietary Engines: Experience working with at least one proprietary game engine (C/C++ OOP or ECS-based UI systems).

• C++ Mastery: Strong C++ programming skills, including proficiency in modern standards (C++17/C++20) and memory management.

• Data & Architecture: Deep expertise in common data structures, algorithms, and MVVM (Model-View-ViewModel) or MVC architectural patterns tailored for games.

• Network Awareness: Solid understanding of Client-Server game architecture and how UI interacts with asynchronous network data and replication.

• Soft Skills: Excellent communication and collaboration skills, with a proven ability to thrive in a fully remote, distributed team environment.

What Makes You Stand Out

• Experience utilizing Unreal’s Gameplay Abilities System (GAS) to drive UI visual feedback (cooldowns, status effects, attribute bars).

• Advanced experience with UI optimization tools (Unreal Insights, Slate Insights) and profiling UI layout passes.

• Familiarity with alternative UI middleware or modern web-tech integration in games (e.g., Coherent Gameface, Rive, ImGui, HTML5/CSS/JS solutions).

• Strong foundation in shader development or material creation specifically for UI effects.

• Experience implementing extensive accessibility features (screen readers, text-to-speech, colorblind modes) in a AAA title.

• Familiarity with scripting languages for UI styling and tools development (e.g., Python, Lua).
