ABOUT THE ROLE:
- You will work on the most critical post-training and reinforcement learning challenges at any given time — including reward modeling, preference optimization (RLHF/DPO), and RL for improving reasoning, truthfulness, and real-world capabilities.
- You will get clarity on your first project before an offer.
BASIC QUALIFICATIONS:
- You believe truth-seeking AI is the most important and challenging problem.
- You are obsessed about building incredibly useful models through post-training and RL techniques.
- You are a power user of AI models and eager to push the boundaries of what’s possible with reinforcement learning and alignment methods.
- If you previously worked on post-training, RLHF, or trained models used by millions of people it’s a big plus, but relevant experience is not required.
- You take pride in your work and thrive in meritocratic environments.
