Junior Customer Success Manager (m/f/d)

About Blockbrain

For mid-sized and enterprise companies in DACH, knowledge is the last real competitive lever. Yet knowledge gets stuck in tools and SharePoint folders — or disappears when experts leave. While IT is still planning, employees are already using ChatGPT and the like — without governance, and sensitive data is leaking out.

With the Knowledge Bots platform, Blockbrain creates what companies truly need: AI-powered knowledge management that is quick to implement, flexibly scales, and operates in a compliant manner. Teams use our GenAI building blocks to build tailored AI assistants, agents, and workflows in minutes — just like Lego.

• Series A funded with strong growth momentum (10x product usage & 5x revenue in 2025)

• Enterprise clients such as Roland Berger, Bosch, IONOS, and Harting from industries including manufacturing, finance, and legal — sectors with the highest security requirements

• ISO 27001 certified, EU AI Act ready. Made in Germany.
  
  

Your Role & Responsibilities

As Junior Customer Success Manager, you are the operational engine of our CS team and work side by side with our Senior CSMs to make key accounts across mid-market and enterprise genuinely successful. You accompany customers from their first pilot to a long term partnership, build real use cases in our no code platform, and are the direct point of contact for user questions on calls. This is your launchpad to build deep product knowledge and grow into an independent manager for complex customer portfolios.

• Support our Senior CSMs in day to day business, prepare review meetings, and take ownership of parts of the customer portfolios

• Run onboarding calls and check ins independently, answer user questions directly on calls, and make sure customers get the most out of our platform

• Handle understanding based and conceptual requests directly with the customer, while technical tickets go to our support manager

• Build concrete Knowledge Bots on the Blockbrain platform, configure workflows, and test them until they work flawlessly

• Analyze how customers use the tool and proactively suggest improvements or new use cases

• Work closely with our Forward Deployed Engineers on complex, customer specific requirements and new integrations

• Create best practice guides, run small trainings to drive adoption, and feed structured customer feedback back to the product team
