Job description

About this positionAt Naval and Offshore Structures, we contribute to a safe, sustainable, and resilient future. Our team designs, analyses, and tests a wide range of mechanical structures for the maritime, offshore, and defence sectors. Ensuring the safety, reliability, and long-term performance of these structures, even under the most demanding conditions and throughout their entire service life, is at the core of our work.We support the Dutch and European maritime industries in their transition towards sustainable shipping through the safe adoption of alternative energy carriers and propulsion technologies, including methanol, ammonia, and nuclear energy. This requires a holistic approach that balances safety, sustainability, and economic viability. Drawing on our expertise in naval architecture, structural engineering, and materials science, we contribute to TNO-wide initiatives aimed at accelerating this transition, including the development of in-depth knowledge on emerging degradation and damage mechanisms associated with new energy systems.To strengthen our team in this field, we are significantly expanding our activities related to ammonia as a hydrogen carrier. We are looking for an experienced professional who can help shape and lead this growth together with the team. If you are passionate about advancing the future of sustainable maritime energy systems, this could be the opportunity for you.What will be your role?As a Senior Scientist Ammonia in Maritime Applications, you will translate your vision on the adoption of alternative fuels into innovative maritime systems and vessel designs. You understand the challenges faced by the maritime industry as it transitions towards new energy carriers and can connect these challenges with TNO's research capabilities and technological solutions. Working alongside a multidisciplinary team, you will analyse, model, and experimentally investigate maritime structures and systems that enable the safe and cost-effective implementation of next-generation fuel technologies. Your expertise in structural and material behaviour will be instrumental in developing solutions that improve safety, extend service life, and enhance economic feasibility. Your work will focus on hydrogen carrier technologies, with a particular emphasis on expanding TNO's expertise in ammonia-based energy systems. The knowledge generated through your research will contribute directly to the development of future regulations, standards, and guidelines, while supporting industry partners in the safe and efficient introduction of ammonia and related technologies within the maritime sector.You will be part of a rapidly growing multidisciplinary team of specialists from diverse engineering backgrounds and will work closely with clients, industrial partners, and colleagues across TNO. As a Senior Scientist, you will provide technical leadership within research projects, initiate and develop new research opportunities, and play an active role in shaping our long-term research strategy. In addition, you will represent TNO in national and international scientific and industrial forums, establish collaborations with industry and academia, and contribute to TNO's visibility through scientific publications, conference presentations, and industry engagement.You will join the Naval and Offshore Structures department, a team of approximately 60 highly motivated experts with backgrounds in naval architecture, civil engineering, aerospace engineering, applied physics, and mechanical engineering. Our primary application domains are defence and maritime & offshore technology. With access to advanced mechanical testing facilities, we combine experimental and computational expertise to address complex engineering challenges and validate innovative structural solutions. Our research spans topics such as the safe implementation of alternative fuels on board ships, the structural integrity of offshore wind turbines, and blast- and shock-resistant naval structures. Together, we tackle some of today's most pressing challenges: accelerating the energy transition while ensuring safety, resilience, and security at sea.What we expect from youYou hold a Master's degree or PhD in a relevant engineering discipline, such as Naval Architecture, Aerospace Engineering, Mechanical Engineering, or Civil Engineering, with a specialization in the design and development of engineering systems and structures.
