Senior Director of Communications

We're here to help the smartest minds on the planet build Superintelligence. The labs pushing the edge? They run on Lambda. Our gear trains and serves their models, our infrastructure scales with them, and we move fast to keep up. If you want to work on massive, world-changing AI deployments with people who love action and hard problems, we're the place to be.

You are passionate about AI, blending creativity with operational agility. You thrive in fast-paced, collaborative environments, balance strategic vision with hands-on execution, and are energized by the challenge of communicating breakthrough technology to the world.
