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

We have a product that is measurably faster than the alternatives and customers who care about speed. What we don't have yet is a clear story, a known audience and a steady presence in the places AI developers pay attention.

You will be our first marketer. This is a hands-on role: you will set the strategy and do the work yourself, from positioning to the first blog post. We need someone who can figure out who our buyers are, decide what we should say to them, and get our founders in front of the right people. What you build becomes the foundation for the rest of our marketing.
