We combine proven curriculum principles with world class interactive design to make meaningful practice something students want to come back to, not something they struggle through.\nWe support what teachers, schools, and parents are already doing by increasing student engagement with high quality, standards aligned practice that reinforces classroom learning. That’s why we’re building:\nFor students: Rewarding and motivating learning experiences that meet students where they are to build real academic proficiency.\nFor educators: Tools that fit naturally into instruction and help students stay engaged while reducing teacher workload.\nFor parents: Activities that help your kid catch up or get ahead, build confidence, and minimize homework battles, whether learning at school or at home.\nWe are committed to helping every person maximize their potential and live a life of meaning. It’s a difficult problem that requires brilliant people and tremendous effort over time.\nLevel is looking for a C++ engine engineer who can make 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, and this role focuses specifically on identifying what the engine actually needs for our product, what can be stripped out, and what must be rewritten or optimized so it performs well on lower-powered devices. This is a role for someone who has worked underneath the game/application layer, with experience working inside an engine and changed how it behaves on constrained hardware.\nWhat You Will Do:\nGet inside our engine and determine what functionality is actually needed for our product, and what can be removed, rewritten, or optimized\n\nProfile and optimize engine and runtime performance across CPU, GPU, memory, binary size, loading time, and (where relevant) battery/power\n\nModify underlying engine/runtime technology to meet mobile and constrained-hardware requirements\n\nWork on memory allocators and footprint, asset streaming, lazy/asynchronous loading, texture compression, and rendering optimization\n\nAddress draw calls, GPU pipelines, shaders, CPU/GPU synchronization, multithreading, and frame pacing\n\nWork with platform graphics APIs (iOS/Metal, Android/Vulkan/OpenGL ES) and debug device-specific problems\n\nImprove startup and load time, binary/package size, and performance across a range of device generations and capabilities\n\nMake architecture and systems design decisions specific to lower-powered hardware constraints\n\nActively experiment with and adopt AI-assisted development tools to improve engineering workflows\n\nQualifications\nNeed to Have:\nStrong professional C++ experience\n\n7+ years of game engine or runtime experience, including comfort working below the gameplay/application layer\n\niOS and/or Android shipping experience is a plus\n\nExperience with constrained hardware and a strong understanding of mobile hardware limitations\n\nExperience profiling and optimizing for CPU, GPU, memory, loading, asset footprint, binary size, and frame rate\n\nExperience modifying underlying engine or runtime technology (not just building features on top of one)\n\nExperience debugging device-specific problems across different hardware generations\n\nStrong architecture and systems design skills\n\nFor 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\n\nNice to Have:\nDirect experience taking an engine or runtime and stripping down, customizing, or optimizing it for target mobile hardware\n\nExperience with Godot: core contribution, C++ engine development, mobile/platform contributions\n\nBackground on a proprietary mobile engine team, where engine internals (memory, rendering, asset systems, platform abstraction, threading) had to be understood deeply\n\nExperience modifying Unreal Engine source itself\n\nExperience with battery/power optimization and low-end device optimization\n\nCuriosity about and hands-on experimentation with AI-assisted development
