Senior AI Engineer (F/M/*)

We are Cologne's fastest-growing AI start-up.

SMEs benefit when internal knowledge becomes immediately usable and intelligent agents can respond to it. We believe in a future where business AI – including agents within amber and other platforms – works on a shared context layer, enabling teams to work faster, handoffs to be seamless, and expertise to remain within the company.
