## About the role

A year ago, reliably working agentic systems barely existed. Nobody has a decade of experience here. So we're not screening for a resume template — we're looking for strong people from varied backgrounds who learn fast, thrive in ambiguity, and can show us what they've built, broken, and understood. You don't need all of this. But you need enough to make a case.

## What they're looking for

- You don't need all of this. But you need enough to make a case
- Foundation models : training, new architectures, RL, reward modeling, scaling
- Evaluation : benchmarks, eval loops, quality measurement, LLM-as-judge, failure analysis
- Frontier topics : multimodal models, agents, tool use, test-time compute, world models
- Published research at ICML, ICLR, NeurIPS, EMNLP, ACL, or AAAI
- PhD in ML/NLP — or equivalent practical experience you can point to
