## Job description

## Who We Are

Over the next few years, every financial institution will have teams of AI analysts working alongside their sharpest minds. Agents have already reshaped software engineering. The same shift is coming for financial services.

At Endex, we're building the most sophisticated AI coworker for finance. We're a team working at the frontier of agentic development and applied finance, in close collaboration with leading research labs and backed by OpenAI ($14M raised in Aug. 2025).

With significant demand after our launch, the world’s largest financial firms recognize agentic financial modeling is the future.

## 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.

Example Projects Include…

- 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

Full-Time Benefits

- Health & Dental Insurance
- Monthly Wellness Stipend
- 401K Matching
- Competitive Salary + Equity
