About this position

Developing software to predict the performance of the latest sonar systems? Planning and evaluating operations with underwater drones? Come work at TNO as an underwater operations scientist!

The world has been living in a new geopolitical reality since the invasion of Ukraine and has only become more unpredictable since then. Our society, politics, government, armed forces and knowledge institutions must move quickly. As a knowledge institute in the ecosystem, TNO plays a crucial role with a thousand highly educated employees in the field of innovations for Defence & Security. We actively contribute to a safer world, both nationally and in a European context.

The Acoustics and Underwater Warfare division brings together all acoustic expertise within TNO and works mainly for the Royal Netherlands Navy. The Underwater Operations & Seabed Security department focuses on research and development in the field of autonomous underwater systems. Applications include detecting sea mines with autonomous underwater and surface drones, stand-off anti-submarine warfare, underwater communication or protecting critical infrastructure on the seabed. We develop state-of-the-art acoustic sensor systems, including advanced data processing algorithms for visualization and information extraction to generate situational awareness. We also model to be able to predict the expected performance against underwater threats under various operational conditions.

What will be your role?

As a scientist, you will work in multiple research and development projects to develop solutions for our customers. You will work together with other highly motivated researchers from your team. You will participate in multiple projects, each with their own team. No two projects are the same, so there are plenty of opportunities to develop yourself further.
