Partnership & Growth Lead | 6 Month Contract | Immediate Start

Temporary, Full-time · Berlin, Potsdam
50,000 - 60,000 € per year
Your mission
We're looking for a Partnership & Growth Lead to accelerate our growth over 6 months. You'll connect with pilot users, build strategic partnerships, and validate our product-market fit across developer tools and enterprise AI teams.
This isn't traditional sales - it's about building a movement. You'll help technical teams understand that testing deserves the same sophistication as development, while showing business stakeholders how their expertise can shape AI quality.
