Berlin

Chief of Staff (m/f/d).

FULL TIMELEADERSHIPPEOPLE & OPS

Your mission

You work directly with our CEO on whatever matters most for theion at any given moment. Real start-up culture and speed. The scope of this role grows with the company. You should enjoy getting into unfamiliar topics quickly, forming your own well-founded opinion and taking ownership before anyone hands you a detailed brief. Battery technology is part of the daily conversation here, so curiosity for deep tech matters more than a background in it.

Your tasks

  • Investor relations. You own the relationship with our investors and the board, from regular investor updates to preparing board meetings and writing the minutes afterwards.
  • Fundraising. Together with the CEO, you run our financing rounds. You build the investor materials, keep the pipeline and the data room in order and follow up until the term sheet is signed.
  • Business development for our spin-off. We hold a patented process that we want to bring to market as a separate business. You develop its go-to-market, identify the industries where it creates the most value and open the first conversations with licensing partners.
  • Representing theion. You present the company at conferences, industry events and university formats, and you are often the first person investors and partners meet.
  • Internal strategic projects. You pick up the cross-functional initiatives that move the company forward, for example, simplifying our internal processes with AI, and drive them until they actually work in daily operations.
  • AI. You are familiar and highly proficient in AI use. But you are also critical of the output.
  • Finance. You support the CEO on all finance topics, from cash planning to controlling, until the year-end closings, together with the tax advisor.
  • Sparring partner to the CEO. You challenge decisions, analyse the numbers, talk to the people who know the problem first-hand and turn all of it into clear recommendations.

Your profile

MUST- HAVES:
  • You have a degree in business, economics or a similar field
  • You have at least 2 years of experience as a Founder Associate, Chief of Staff, or in a similar role working closely with executive leadership, ideally in a fast-growing startup, venture capital, strategy consulting, or a comparable environment.
  • You speak and write fluent English - our company language is English, where all internal communication and meetings are done.
  • You speak and write fluent German - you will communicate with external partners and potential investors independently, incl. pitching the company presentation, in German.
  • You can commute to the on-site in Berlin-Adlershof.
NICE-TO-HAVES:
  • You already have a network among deep-tech and climate investors.
  • You bring a background in deep tech, hardware, energy or materials and are comfortable discussing the technology.
  • You have worked in a multicultural environment with highly skilled experts.
  • You are AI-native. For you, that goes well beyond chatting with an AI assistant: you work agentically, set up your own agents and manage them as part of your daily workflow.
  • You have already achieved results early in your career that stand out.
  • You do not wait for instructions. When you see a problem, you work out what it takes and get the solution moving yourself.
  • You measure responsibility by outcome. A sent email is not a finished task for you, and you stay on it until the problem is solved.
  • You learn fast, think analytically and can turn complex technical information into decisions that the board or investors can understand clearly.
