About this position

The security of the Netherlands and its allies requires well-informed decision-making in an increasingly complex geopolitical landscape. Modern military operations are shaped by technological developments, evolving threats, and complex operational choices across the land, air, maritime, and space domains.

Within TNO Defence, Safety & Security (DSS), analysts, scientists, and engineers develop knowledge and technologies that support the Armed Forces in preparing, executing, and evaluating military operations. You will work within the Electromagnetics & Military Operations (E&MO) division, where you contribute to analysing complex operational challenges and supporting decision-making through data, models, and analyses.

Working at E&MO means operating at the heart of defence innovation. Here, project managers, researchers, engineers, and analysts collaborate closely on technologies and knowledge that are essential for modern military operations. Specialists and generalists work side by side on challenges ranging from concept development and system architecture to integration, testing, and validation in realistic operational environments.

Do you recognize yourself in this role and would you like to apply your talents to challenges that truly matter? Then we warmly invite you to apply.

What will be your role?

As an Operational Analyst, you will work on complex operational challenges for Defence. You will support decision-making by developing models, simulations, and analyses that contribute to future military capabilities, operational concepts, and investment decisions.

Your responsibilities include:

• modelling and simulating military operations;
• analysing current and future operational concepts;
• performing quantitative analyses related to deployment, effectiveness, capacity, and readiness;
• developing algorithms and analytical models;
• analysing qualitative and quantitative datasets;
• advising on deployment, procurement, sustainment, and further development of equipment;
• preparing research proposals and translating client questions into concrete analyses;
collaborating with Defence, international partners, and multidisciplinary teams.

You will primarily work from a quantitative perspective, while also maintaining a strong understanding of the operational context behind the data. You translate complex operational challenges into practical models and analyses, thereby directly contributing to the effectiveness of military operations.

Depending on the project, you will work on challenges across different domains, such as land, maritime, and air operations. In projects with a focus on Air Power, for example, you will contribute to analysing and improving air force operations through applied scientific research, modelling, and simulations. In doing so, you work closely with Defence partners and translate complex operational challenges into concrete and actionable solutions. In some projects, you may also work temporarily on-site at Defence locations.

What does UMBRA mean?

UMBRA is the entry point for technical and analytical talent within TNO’s Electromagnetics & Military Operations (E&MO) division, part of the Defence, Safety & Security unit. UMBRA—named after the Latin word for “shadow”—is a “shadow group” where both early-career talent and senior experts join the E&MO division.

Together, you will work on mission-critical Defence challenges with societal impact, with a strong focus on short-cycle innovation. In practice, this means striving for results within months rather than years. Depending on your level of experience and available team capacity, you will also start working directly on projects within one of the division’s research groups.

In addition, you will follow an onboarding program within UMBRA tailored to your experience level and development goals, helping you find the right long-term position. You are expected to transition to one of the division’s research groups after 3–6 months. UMBRA is based in Rijswijk, where you will start your role; after some time, you will move on to the division located in The Hague.
