The Role

The Frostbite Engine group in EA Romania is looking for a UI Systems Rendering Engineer for the Frostbite team in Bucharest.

Frostbite is EA's state-of-the-art multi-platform game development engine, powering games such as Battlefield, FIFA, Madden, Plants vs. Zombies, Need for Speed, Anthem, and Star Wars Battlefront II. We currently focus on AI Systems, profiling tools, release systems and we just started to build the UI Systems team. The mission of the UI team is to develop tools, workflows, and runtime features that support the diverse UI needs of game teams throughout the world.


The UI domain has unique rendering challenges and requirements that are specific to the problem-space. This role will require you to design and build cutting-edge features necessary for games to ship scalable, performant, and high-quality UI across multiple platforms and with varying hardware capacities and resolutions.

You will develop the tools, features, and pipelines necessary for game developers to build UI content, including:
• Create layouts that work on multiple platforms and aspect ratios
• Animate UI content in response to game state or user actions
• Manage and processing user input across a variety of input devices
• Bound and display game data within the UI
• Gather requirements from game team developers and write technical design specifications for implementing each new feature
• Build sample content, clear documentation, and training materials for game team UI developers
• Provide support to game team UI developers by addressing any bugs or issues and coordinating cooperative development of essential features

• Bachelor's degree or higher in Computer Science, Engineering or Software Engineering or equivalent
• Object-oriented programming experience and good understanding of OO design principles
• C++ programming skills. C# and WPF experience are a plus
• Experience creating and optimizing UI-related render tech at the engine level in a multithreaded environment
• Familiarity with UI rendering technologies and techniques such as:
• MSDF font rendering
• SVG rasterization
• Font rendering directly from spline data
• Effective glyph cache manipulation
• Efficient Texture Aliasing
• Efficient Hierarchical Masking for UI components
• Custom shader implementations including ''uber'' shaders, vertex/pixel shaders, and compute shaders for optimizations
• Knowledge of batching optimizations and state-change reduction methodologies for UI
• Efficient UI <-> World rendering integrations (efficient ''blur effect'' behind UI elements, in-world UI, etc)
• CPU-offloading to the GPU for UI elements (GPU skinning, tinting, clipping and culling)
• Knowledge of merge planes, color spaces, alpha blending issues (e.g. premultiply-alpha) a plus
• Knowledge of Agile/Scrum processes
