## Who We Are

Over the next few years, every financial institution will have teams of AI analysts working alongside their sharpest minds. At Endex, we're on a mission to bridge the present to the inevitable by building the most sophisticated digital coworker native in Excel. We're a team working on the frontier of agentic development and applied finance, in close collaboration with leading research labs and backed by OpenAI ($14M Raise in Aug. 2025).

With significant demand after our launch, financial firms across the country recognize agentic AI in financial modeling is the future.

## About the Role

Location: New York City Commitment: 5-6 days in-person

As Founding Designer at Endex, you'll define how financial professionals interact with AI in their most critical workflows.

- User-Obsessed: You deeply understand user workflows and pain points. You conduct research proactively and let insights drive your design decisions
- Technically Fluent: You understand technical constraints and can work effectively with engineers. You know what's possible in web technologies and can design within platform limitations
- Detail-Oriented: Your designs are polished and production-ready
- Fast Executor: You ship quickly, and iterate based on feedback
- Strong Communicator: You articulate design decisions clearly and can advocate for user needs across the organization

## Requirements
