About Blockbrain

Ready to take charge of the IT infrastructure of a leading AI startup? As a (Senior) IT Manager, you will take ownership of our cloud-based infrastructure and ensure that our rapidly growing team can work productively and securely at all times. You will identify the best tools and AI solutions to automate internal processes and continuously increase our productivity. Your mission: To create a secure, scalable IT environment that can keep pace with our growth from 40 to 200+ employees.

For medium-sized companies, knowledge is the last real competitive lever. But knowledge is locked away in tools and SharePoint folders—or disappears when experts leave. While IT is still planning, employees have long been using ChatGPT & Co.—without governance, and sensitive data is flowing out.

With the Knowledge Bots platform, we create what companies really need: AI-supported knowledge management that can be implemented quickly, grows flexibly, and functions in a compliant manner. Teams use our GenAI construction kit to build customized AI assistants, agents, and workflows in minutes—just like Lego.

What sets us apart:

  • Market-leading traction: Enterprise deals won against MS Copilot, Perplexity & ChatGPT – with the highest conversion rates in the industry
  • Strong partners & customers: Roland Berger, EY, Adesso, IONOS, Stackit, Bosch, Kärcher, Harting, LBBW trust us
  • World-class team: Founders and executives from Statista, Bosch, WHU, IBM, Amazon, Trumpf – experts in GenAI, B2B SaaS, and cybersecurity

Made in Germany. DSGVO-konform. Enterprise-ready.
