Senior Mobile Engine Architect: Lean, Fast, On-Device

Level AI; Austin (TX); On-site; USD 140,000 - 200,000; Full time

Job summary

Level AI is seeking a C++ engine engineer to make the engine lean, efficient, and reliable on mobile and other constrained hardware. We are building a larger game and learning platform on a forked version of Godot, focusing on what the engine truly needs and what should be rewritten or stripped for low-powered devices.

You will dive into engine internals, optimize memory and rendering, work with iOS/Metal and Android/Vulkan/OpenGL ES, and drive architecture decisions to support a broad range of

Qualifications

• 7+ years of game engine or runtime experience, including below gameplay layer.
• Strong C++ proficiency and experience modifying engine/runtime internals.
• Experience shipping on iOS and/or Android and working with mobile limits.
• Ability to profile and optimize CPU, GPU, memory, and binary size.
• Experience debugging device-specific problems across hardware generations.
• Familiarity with platform graphics APIs (iOS/Metal, Android/Vulkan/OpenGL ES).

Responsibilities

• Get inside our engine and determine what functionality is needed and what can be removed or optimized.
• Profile and optimize engine/runtime performance across CPU, GPU, memory and loading.
• Modify underlying engine/runtime technology for mobile and constrained hardware.
• Work on memory allocators, asset streaming, lazy loading, and rendering optimization.
• Address draw calls, pipelines, shaders, and CPU/GPU synchronization.
• Collaborate with platform graphics teams and debug device-specific problems.
• Improve startup time and footprint across device generations.
• Contribute to architecture decisions for low-powered hardware.
