We're on a mission to build the most capable digital coworker in the world.

About the Role

Location: New York City Commitment: 5 Days In-Person

We're looking for engineers who want to work on category-defining AI work. Building agents with the performance and reliability Wall Street demands is one of the hardest applied AI problems out there.

Design and ship the core agentic systems that power Endex across planning, tool use, memory, long-horizon task execution.

Partner with customers to understand finance workflows, and leverage learnings to improve our product

Build the evals, datasets, and post-training pipelines that turn raw model capability into a product analysts trust

As one of our earliest engineers, you'll shape our architecture, our hiring bar, and the engineering culture

You may be a fit if

You have architected and built scalable systems

You have worked on agentic products or infrastructure and have informed opinions on reliability and performance of complex multi-step systems

You have deep experience with API design, service communication patterns, and database optimization

You have an iterative mindset where you develop proof of concepts, make decisions quickly, and ship v0s

You have strong software engineering fundamentals and enjoy owning the full lifecycle of production services
