Chief of Staff - #2678242

What We’re Looking For

We're looking for a Chief of Staff to work directly with our CEO and co-founders. You'll own some of our most consequential work: the Series A, the operating cadence of the founding team, and whatever question nobody's picked up yet. Some of it is analytical, some is coordination, some is just going and finding the answer yourself. The scope isn't fixed and it won't become fixed.

The day-to-day

• Projects: you take the CEO's priority projects and see them through, from first framing to shipped outcome
• Capital: you drive the Series A: financial model, dataroom, investor materials, diligence
• Cadence: you run OKRs, decision logs, and DRIs for the founding team, so decisions get made once and written down
• Analysis: you build our view on the market, competition, and regulation and how procurement evolves — good enough for the founders to decide on
• Execution: you clear blockers across engineering, operations, and commercial, and across our entities
• Special projects: whatever needs technical curiosity, operational discipline, and discretion
  
  

You should apply if you

• Track record: 3+ years at a venture-backed startup, in strategy, defense consulting or in VC - and did more than your title required
• Writing: excellent, and short. Numbers before adjectives
• Initiative: finished something nobody asked you to start
• Discretion: handle export-controlled and commercially sensitive material properly, every time
• Languages: fluent German and English, including in writing
  
  

Nice to haves

• Fundraising: you've worked a Series A or later round, from either side of the table
• Technical: engineering, physics, or another quantitative background
• Public sector: experience with military, ministerial, or procurement stakeholders
  
  

What We Offer

• Real impact & ownership: Shape high-tech defense systems and take responsibility from day one.
• Mission-driven environment: Work on technologies that matter for European security and sovereignty.
• Competitive package: Competitive salary, EGYM Wellpass, corporate benefits, and equity options aligned with role and level.
• Deep tech environment: Get hands-on experience with cutting-edge drone technology and real operational use cases.
• Grow fast: Steep learning curve for juniors, strategic influence and leadership opportunities for seniors.
• Startup mindset meets defence innovation: flat hierarchies, fast decisions, and space for your ideas.
• Strong team: International, driven colleagues and a culture built on exchange, trust, and shared success.
