Develop frontier language models and agents. Training, reinforcement learning, and inference in one system, on River Cloud or your own GPU cluster. Backed by General Catalyst.
About the role
We're looking for an Office Manager to own the day-to-day operation of our office. This is the role that makes everything else run: visitors are greeted well, supplies are ready and re-stocked, deliveries land as expected, the space itself is safe and well-maintained, and vendors complete scheduled work. This is a hands-on, in-office position with real responsibility — you'll be the person everyone relies upon.
What they're looking for
- Prior experience in a role carrying a high level of responsibility — a position where you were trusted to own outcomes, handle sensitive information, and make decisions without being managed closely
- Genuine enthusiasm for technology and AI, with a habit of finding tools that make work faster and better
- Excellent written and verbal communication skills
- Strong organizational judgment: you can hold many small threads at once and know which one matters most right now
- Practical, hands-on approach to facilities issues — comfortable troubleshooting on the spot and knowing when to call in a professional
- Comfort with standard office software and a willingness to learn new systems quickly
