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
