Founding Engineer (Staff level)

https://www.3ive.ai

A software engineer today has Claude Code and Cursor. A mechanical engineer designing the next jet engine? Still searching Excel sheets and asking whoever has been around longest.

We're building the AI co-engineer for physical products - in production with major European manufacturers. Working at the intersection of 3D, reasoning, and long-horizon agents.

Stack: Python, TypeScript, multi-agent orchestration, LLM integrations. Recent work includes a custom multi-agent SDK for durable long-horizon execution and a production pipeline wrapping a C++ CAD SDK.

We are a small team and you own hard problems end-to-end. We offer a competitive salary + early equity.
