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

What you'll do

Build and ship autonomous AI agents that process orders, generate quotes, and make inventory decisions without human intervention

Integrate with messy enterprise systems - ERPs, CRMs, inboxes, and phone systems that distributors actually use

Write high-performance backend services that handle inventory optimization algorithms, complex pricing logic and more
