About Blockbrain

For mid-sized companies, 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.

Role & Impact

You’ll work across our engineering organization. In areas like Agents, Knowledge, Enterprise, or Mobile - taking meaningful, sometimes ambiguously defined problems from understanding through implementation to production monitoring. You’ll own problems end-to-end, make technical decisions within your scope, and use coding agents as a core part of how you build. Not as a novelty, but as a multiplier for speed, quality, and technical depth.
