Description

Help Build Europe's Hypersonic Capability
At Hypersonica, we’re redefining what’s possible in European defence technology. We exist to deliver speed, resilience, and technological independence at a pace that sets a new standard. We are a small, elite team working on problems that matter, and solving them fast.
By joining Hypersonica, you’re not stepping into a predefined role. You’re joining a talent dense environment where every individual shapes the direction of the company. Our philosophy is to hire a small number of exceptional people with broad, deep technical capability, strong judgement, and the ability to operate autonomously.
We hire for talent, not rigid boxes. This role represents a business need, but the way it evolves will be shaped by the individual. If you’ve achieved what others said was impossible, or you bring a unique combination of skills that doesn’t fit a traditional mould, we want to hear from you. The work you do here directly contributes to Europe’s technological independence.

What you'll do

  • Support our Programmes team and its leadership, ensuring that the right people come together at the right time.

  • Coordinate calendars, travel, and meetings, handling even complex scheduling with composure and clarity.

  • Organise visits from customers, investors, partners, and political stakeholders at our office.

  • Help create a professional and positive office environment and ensure that everything runs smoothly on site.

  • Support events and workshops, helping to create memorable experiences.

  • Bring order to processes, documents, and tasks, ensuring that nothing slips through the cracks.

  • Work closely with the Leadership Team and gain exciting insights into building a fast-growing Technology company.

  • Take ownership, think proactively, and implement topics independently.

Who you are

  • You have strong organisational skills and maintain a clear overview even when multiple topics are running simultaneously.

  • You work in a structured, reliable, and independent manner, and enjoy driving things forward.

  • You think ahead, recognise where support is needed, and proactively take on tasks.

  • Communicate professionally, courteously, and confidently with a wide variety of internal and external stakeholders.

  • Ideally, you have initial professional experience in assistance, office management, hospitality, event management, or a comparable area. Career changers with strong organisational skills, service oriented, and a hands-on mentality are warmly welcome.

  • You enjoy working in a dynamic environment and can set priorities when requirements change at short notice.

  • You are confident in using Microsoft 365, particularly Outlook, Teams, PowerPoint, and Excel.

  • You have excellent written and spoken German and English skills.

  • You are keen to take responsibility, learn, and grow alongside a rapidly growing company

What we offer

  • A mission driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security.
  • Daily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow.
  • High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes.
  • A fast paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions.
  • A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly.
  • Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.
At Hypersonica, every hire raises the bar. We are deliberately small, intensely capable, and deeply mission-driven. If this role feels like a strong fit, or if you believe you bring something exceptional that goes beyond the description, we encourage you to apply.
Hypersonica is an equal-opportunity employer and assesses candidates solely on merit, capability, and potential.
You can apply directly to this role or reach out to Nathan Sweeney, Head of Talent. We review every application and aim to respond to all candidates within two weeks, whether the answer is yes or no.
