Work with platform graphics APIs (iOS/Metal, Android/Vulkan/OpenGL ES) and debug device-specific problems
Improve startup and load time, binary/package size, and performance across a range of device generations and capabilities
Make architecture and systems design decisions specific to lower-powered hardware constraints
Actively experiment with and adopt AI-assisted development tools to improve engineering workflows
Qualifications
Need to Have:
Strong professional C++ experience
7+ years of game engine or runtime experience, including comfort working below the gameplay/application layer
iOS and/or Android shipping experience
Experience with constrained hardware and a strong understanding of mobile hardware limitations
Experience profiling and optimizing for CPU, GPU, memory, loading, asset footprint, binary size, and frame rate
Experience modifying underlying engine or runtime technology (not just building features on top of one)
Experience debugging device-specific problems across different hardware generations
Strong architecture and systems design skills
For candidates from Unity or Unreal backgrounds: demonstrated experience going below the engine's abstractions (e.g., native C/C++ work, IL2CPP, native plugins, or modified engine source), not solely C#/Blueprint-level mobile shipping experience

Experience modifying Unreal Engine source itself
Experience with battery/power optimization and low-end device optimization
Curiosity about and hands-on experimentation with AI-assisted development tools
