About this position

Contributing to our security. Can you see yourself doing that? Become a Business Developer for Land & Amphibious Operations at TNO in The Hague.

No two working days are the same, but one thing is certain: as a Business Developer in the field of Land and Amphibious Operations, you are in constant contact with the Royal Netherlands Army (including the Netherlands Commando Corps and Air mobile Brigade), the Netherlands Marine Corps and other Defence units, industry partners, fellow research organizations, government bodies, and, of course, your colleagues within TNO.

You connect our clients’ operational needs with the innovative strength of the Netherlands, helping to develop new and meaningful capabilities for both our armed forces and our industry.

What will be your role?

Together with a team at TNO, you will work on innovative solutions for the land and amphibious operations of the Netherlands and its allies. There will be a great deal happening in this domain in the coming years. That is why you will actively engage with the Ministry of Defence and industry partners. You take initiative and guide ideas towards concrete projects, helping to bring military capabilities into operation as quickly as possible.

You build and maintain long-term relationships with our clients. You actively connect long-term knowledge development with shorter-term technology projects, ensuring that innovation translates into practical impact.

You stay up to date with developments in the field by attending national and international conferences and trade fairs, engaging with key stakeholders, and visiting a wide range of clients and partners. In doing so, you contribute to the future readiness and operational effectiveness of the armed forces and help strengthen the security of the Netherlands in a rapidly changing world.

You will join a team of experienced business developers within the Electromagnetics & Military Operations (E&MO) market team of TNO’s Defence, Safety & Security (DSS) unit. Our mission is to enhance the effectiveness of defence and security organisations through the development of smart technological solutions in the electromagnetic spectrum and through operational analysis of current and future military operations. We also aim to contribute to a strong international position for Dutch industry.

Our market team is diverse in both background and experience. We rely on one another’s strengths and confidently hand over responsibilities when needed. There is ample opportunity to learn, job satisfaction is highly valued, and colleagues are always willing to support each other. Above all, a shared enthusiasm for our profession and for defence and security is one of the key things that unites us.

What we expect from you

Your interest lies in the world of technology and defence, specifically the Royal Netherlands Army and/or the Netherlands Marine Corps. You combine a relevant professional background or strong affinity with these domains with an entrepreneurial, social, and enthusiastic mindset, and you are able to switch gears quickly. Building relationships comes naturally to you, and you enjoy connecting with people; you act as a bridge between stakeholders.

In addition, you can easily adapt your communication style to different audiences and navigate both national and international environments. You provide structure and direction (for example in proposal processes or collaborations with government and industry partners) and are able to think and act strategically while also driving short-term actions. You are curious, analytical, and enjoy getting to the bottom of complex challenges. You use your creativity to bring together the right expertise from across TNO.

What else do you bring?

  • Master's degree level (WO) in terms of working and thinking.
  • Demonstrable affinity with innovation, technology, and the military domain, preferably the Royal Netherlands Army and/or the Netherlands Marine Corps.
  • At least 10 years of relevant work experience, for example within Defence, or as a consultant or business developer in the commercial sector.
  • Entrepreneurship, flexibility, and collaboration are competencies that come naturally to you.
  • Excellent command of both Dutch and English, spoken and written.

What you'll get in return

Challenging and varied work with a real impact. And plenty of opportunities as, at TNO, you are in charge of shaping your career. In addition, you will be given every opportunity to develop yourself.

TNO offers optional employee benefits, enabling you to tailor your benefits package to match your personal situation. You may also expect:

  • An extremely professional, innovative working environment where colleagues are leading experts in their field.
  • The opportunity to attend courses, workshops and conferences, and to receive training and coaching based on your needs.
  • 33 days annual leave plus a flexible holiday that can be used on a cultural, religious, or otherwise important day of your choosing (on a full-time basis).
  • We offer a comprehensive and flexible mobility plan that also includes full compensation for public transportation for commuting and business travel or a lease car.
  • Great social events with your team and other TNO colleagues. That’s how you will get to know a lot of people really quickly.
  • Flexible working hours, the possibility to work parttime (32 or 36 hours) and the possibility of working from home.
  • A good pension scheme.

TNO as an employer

Our people are at the heart of TNO. Their curiosity, expertise and entrepreneurial mindset make it possible to deliver high-impact research and innovations that contribute to society’s sustainable wellbeing and prosperity.

Your talent and ambition have every opportunity to flourish at TNO. You work with experts (both within and beyond TNO), have access to advanced technology and the freedom to explore, experiment and innovate. Our strength lies in independence, reliability and collaboration.

As you will be working for clients in the domain of defence and security, a Certificate of No Objection issued by AIVD (the Dutch General Intelligence and Security Service) is mandatory. This means you will have to undergo a security screening.

Innovation with purpose: that is what TNO stands for. We develop knowledge not for its own sake, but for practical application. TNO connects people and knowledge to create innovations that boost the competitive strength of industry and the well-being of society in a sustainable way.
