- Practical experience creating applications powered by LLMs and autonomous agents.

- A strong academic or startup background.
- Comfort working independently and creating new systems with little guidance.

- Prior experience founding a company or serving as an early engineer on a new product.
- Personal projects, such as self-built AI tools or shipped products, that demonstrate initiative.
