Head of Compute and Capacity - Lithos Ai

About Lithos Lithos builds the fastest agentic inference on the planet: frontier open models at full precision on standard GPUs. Our engine currently holds top spots on Artificial Analysis for output speed, time to first token and end-to-end latency on models like DeepSeek and Kimi. We serve inference to growing startups as well as FT500 companies through a public API or on their own hardware. Lithos was founded by Carnegie Mellon computer science professors who spent years turning systems research on inference and GPU virtualization into a product. We are a small team, and this is one of our first ten hires. Why this role matters For an inference company, capacity is existential. Every promise we make on speed, price and uptime depends on having the right compute, in the right place, at the right price, before the demand arrives. You will own that. This is the most important commercial seat at Lithos after the founders, and it reports directly to them.
