Ultrasound and Acoustics Scientist | the Hague

Contribute to measure sound, model sound and predict how it propagates through solids, water and air. Do you envision? Become Underwater Acoustics Scientist TNO in The Hague.

About this position

We are looking for a devoted new colleague to expand TNO’s Acoustics & Sonar (A&S) department further. Acoustics & Sonar is the department where all of TNO’s acoustic expertise comes together. The group consists of approximately 85 people, including the people from the electro-mechanical workshop. We feel the drive to deliver world-class work but manage to maintain a casual and informal atmosphere where your professional development is a key element The A&S department covers a wide range of topics, from sonar applications and noise control to ultrasonic systems. We measure sound, model sound to predict how it propagates through solids, water and air and develop advanced data processing schemes to extract useful information from measurements. We use sound to our advantage for finding objects, such as submarines, sea mines, intruders, underwater infrastructure, sea life, etc. However, sometimes sound can be a nuisance and have adverse effects if perceived as too loud. In these cases, we know how to reduce the sound levels and to design measures to reduce the detectability of military naval platforms and decrease the adverse effects for platforms, humans and sea mammals. In addition, we are developing innovative ultrasonic sensors and instrumentation for integrity monitoring and composition analysis for industrial applications – primarily in the aviation, semiconductor, and medical industry.

What will be your role?

As an Ultrasound and Acoustics Scientist, you will typically be active in multiple applied research and development (R&D) projects to develop solutions for our customers in different application domains. You will use your knowledge and experience to help meet our customer’s needs. Initially, we expect you to contribute technically to projects and learn more about the needs of our potential customers. We encourage you to actively contribute to developing innovative measurement concepts within the different domains in which we are active. Projects vary in size and nature, from researching the potential of a theoretical concept to building equipment that works in the field and from small projects running several weeks to large international consortium projects running for multiple years. Each project has its own team, and no two projects are the same, so expect lots of opportunities to develop yourself further.

Your activities will include the following:

  • Contributing to our existing portfolio of R&D projects with your knowledge and experience
  • Developing new concepts and ideas leading to new projects
  • Designing, modelling and experimentally validating novel ultrasonic measurement equipment
  • Developing novel measurement algorithms and associated signal processing
  • Stimulating cooperation with colleagues
  • For experienced scientists: coaching and guiding our junior scientists

If you feel that you can help us progress in these areas and are looking for a job that is meaningful to society, offers lots of variation, and will challenge you as a scientist, you have found your match!
