## About the role

Creating an investable index from a conversation with AI isn't a traditional engineering problem. Users aren't filling out forms or clicking through dashboards—they're collaborating with an intelligent system to express a thesis, understand how it's constructed, and iterate on it over time. We're looking for a Principal Product Engineer who thrives in ambiguity, enjoys solving complex technical problems, and wants to define what AI-native investing looks like.

## What they're looking for

- You've spent years building products, not just software, and understand the difference
- You naturally think about customer outcomes alongside technical implementation
- You have strong engineering fundamentals and are comfortable working anywhere in the stack when the product requires it
- You're able to decompose messy, ambiguous problems into simple, maintainable systems
- You know when to invest in architecture and when to optimize for shipping
- You communicate technical ideas clearly and enjoy working closely with designers, researchers, and founders
