Who We Are

Endex builds AI agents that handle complex, end-to-end work for the world's most demanding teams. Today we're deployed across leading financial institutions and Fortune 500 companies, embedded in the tools and workflows they rely on. We operate at the frontier of agentic knowledge work, partnering closely with top AI research labs and backed by the OpenAI Startup Fund. 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.

Our technical staff works across the stack: agent architecture, evals, model post-training, and new product surfaces. You'll ship to the largest financial firms in the world.

  • 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
