## About the role

We're looking for a high-trajectory SWE to build the AI agents that will automate how $2T of industrial goods move through the supply chain. Our AI agents don't have users - you don't upend an industry's business model with human-in-the-loop copilots. You'll work directly with the founders to build autonomous systems for the core functions of $Xbn+ industrial customers.

## What they're looking for

- A systems-minded engineer who wants to build software that runs real businesses. Specifically:
- Experience with Next.js, TS, Python (FastAPI), PostgreSQL - our core stack
- Familiarity with C# is a plus for working with legacy enterprise SDKs
- You've racked up 1000s of hours in combined LLM usage and productizing - you have a deep familiarity with them, and deep knowledge of LLM research, agents, tool calling, robustness
- We hire on trajectory, not resume length
