## About the role

Drug discovery has a translation problem: more than 95% of drugs that succeed in animal models fail in humans. We're building the alternative: human-first drug discovery, powered by organoids and AI, running on real human biology from the very first experiment.

## What they're looking for

- A pre-IND regulatory expert. You understand how the FDA operates at the discovery and translational stages: what data packages are best up to IND, what bridging studies look like, and how to present them
- VP-caliber. Opinionated, decisive, comfortable with high-stakes judgment calls. You can say "we are not going to do that, here's why" with the same conviction as "we are doing this, here's why."
- Energized by the bet. You see human-first drug discovery as one of the most important shifts in pharmaceutical science in a generation, and you want to be the person calling the scientific shots
