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.

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

A role with real proximity, real impact, and real growth

You are not “just” support. You are the CEO’s right hand — a trusted strategic sparring partner, operational coordinator, and executor for CEO-level priorities and special projects. The role is primarily strategic with hands-on responsibility; classic EA tasks make up only a small part of it.

You work directly with the leadership team, turn complex topics into clear priorities, accelerate decisions, and make sure important initiatives move from discussion to execution.

Your Role & Responsibilities

• Structure and drive CEO priorities: You sharpen priorities, prepare decisions, and keep complex topics clear and execution-ready.

• Own special projects: You drive CEO-level initiatives that do not fit neatly into existing org structures — for example Series B and strategic partnerships.

• Manage stakeholders: You coordinate internal and external stakeholders on behalf of the CEO and ensure alignment, accountability, and follow-through.

• Prepare board, investor, and leadership materials: You structure board decks, executive updates, briefings, keynotes, presentations, and decision-making materials.

• Increase efficiency in the CEO’s day-to-day: You coordinate agenda, meetings, offsites, and key appointments where they create the biggest leverage, and ensure clear next steps.

• Build scalable structures: You help evolve SOPs, workflows, and internal processes to improve transparency, speed, and scalability within the executive team.

• Support OKRs and strategy execution: You help translate strategic priorities into measurable goals and clean execution.

At Blockbrain, we don’t just talk about AI — we use it every day. In this role, you will:

• Use AI tools to make research, structuring, and document creation more efficient

• Use AI to synthesize and prepare information from meetings, stakeholder conversations, and board materials

• Test new workflows and automations to make collaboration smarter and more scalable

Your Profile

• Several years of experience in executive support, business partnering, operations, consulting, or a similar role — ideally in a startup or scale-up environment

• You think strategically and work hands-on: you keep a clear head in fast-moving environments and reliably drive topics to completion

• You are strong in stakeholder management, communication, and prioritization — confident, discreet, and with strong judgment

• You have a solid understanding of boards, investor relations, fundraising, or complex cross-functional processes

• You work in a structured, proactive, and solution-oriented way and spot what needs to happen before it becomes a problem

• You are confident with MS 365, Slack, Atlassian, Personio, or similar tools and learn new systems quickly

• You speak and write excellent German and English and present professionally, friendly, and with confidence
