## About the role

Creating an investable index from a conversation with AI isn't a traditional machine learning problem. Users aren't simply prompting a chatbot—they're collaborating with an intelligent system that must reason over financial information, construct investment methodologies, evaluate evidence, and continuously improve as new information emerges.

## What they're looking for

- You've spent years building production AI systems, not just training models, and understand the difference
- You naturally think about product outcomes alongside model performance
- You have strong machine learning and software engineering fundamentals and are comfortable taking ideas from research through deployment
- You're able to decompose difficult research problems into practical, scalable systems
- You know when to pursue state-of-the-art techniques and when simpler solutions deliver better outcomes
- You communicate technical ideas clearly and enjoy working closely with engineers, designers, and founders
