About the Company
Luma AI is a company that pushes the physical limits of current hardware to train Omni models that understand the world.
Job Description
We are looking for engineers who are tired of high-level abstractions and want to work on the metal that powers the AI revolution. You will operate at the jagged edge where software meets hardware, responsible for maximizing efficiency from our heterogeneous fleet of NVIDIA and AMD accelerators.
Requirements
- Low-Level Fluency: You are not afraid of the kernel. You understand interrupts, memory management, and how the OS interacts with peripheral devices.
- Hardware Curiosity: You understand that software doesn't run in a vacuum. You are interested in the physical constraints of GPUs, networking cards, and storage subsystems.
- First-Principles Reasoning: When a system behaves unexpectedly, you don't just restart it; you investigate the physics of the failure to ensure it is solved permanently.
