We are a Berlin-based startup transforming how industrial materials are bought and sold across Europe. One of the oldest
industries in the world still runs on Excel, PDF and email. We are replacing that with AI that runs the buying and selling
workflow end to end, increasing liquidity, speeding up transactions and reducing waste for hundreds of steel and metal
distributors.
We have strong early traction, real enterprise customers and committed investors. We are a lean, technical team scaling our
enterprise pilots and building the AI infrastructure underneath them.
Your job as Senior Product Engineer is to make sure we deliver on that traction and stay ahead. You partner closely with
Co-founder Simon, who owns sales; you own that we ship, that enterprise customers succeed, and that the product stays in front.
This is a senior, hands-on role with three pillars.
