Our novel fiber-optic technology is redefining underwater security by enabling next-generation sonar solutions to protect critical naval assets and underwater infrastructure.\nYou will contribute to the development of advanced sonar processing algorithms, mathematical models, and software for our next-generation fiber-optic sensing systems. Working closely with experts from multiple disciplines, you will help develop technologies that operate in some of the world's most challenging environments.\nPrevious experience in underwater acoustics, sonar, radar, geophysics or medical imaging is an advantage, but not a dealbreaker. We value strong analytical thinking, curiosity, and the willingness to learn new domains.\nKey responsibilities:\nExecute acoustic modelling and signal processing tasks: Implement and improve algorithms and mathematical models for underwater acoustic sensing systems using principles from signal processing, applied mathematics, statistics, physics, and numerical methods.\n\nAnalyze and interpret experimental data: Process and evaluate fiber-optic datasets from laboratory and field trials to extract insights that support design improvements and validation.\n\nDevelop and test algorithms: Contribute to the development and testing of algorithms for beamforming, event detection, filtering, and data classification under guidance from senior engineers.\n\nDocument and communicate progress: Maintain clear, structured documentation of methods, results, and conclusions. Proactively communicate progress, challenges, and proposed solutions to the team.\n\nCollaborate across functions: Work closely with software, embedded, and hardware engineers to ensure smooth data flow, model integration, and system testing.\n\nImprove team workflows and tools: Identify opportunities to improve data handling, simulation scripts, and processing pipelines, contributing to better team efficiency and clarity.\n\nShare knowledge and provide feedback: Contribute to internal discussions by sharing your learnings, simplifying complex findings for others, and offering constructive feedback on shared work.\n\nWhy Join Us?\nJoin one of Europe’s most promising deep-tech scale-ups.\n\nShape the future of a rapidly growing multidisciplinary R&D organization.\n\nCompetitive salary and benefits package.\n\nEnjoy regular team activities and company events.\n\nFresh team lunches provided3 times/ week.\n\nRequirements\nRequired Qualifications:\nMSc degree (or equivalent) in Electrical Engineering, Applied Mathematics, Physics, Computer Science, Signal Processing, Statistics, Aerospace Engineering, Mechanical Engineering, or another quantitative discipline.\n\n1-3 years of experience in research or development, preferably with sensing systems, applied statistics, or wave-related phenomena or a PhD in a relevant discipline.\n\nA strong background in physical modelling, underwater acoustics, wave propagation, signal processing, sonar, applied mathematics, or equivalent.\n\nGood understanding of several of the following topics: digital signal processing, statistical signal processing, estimation theory, numerical methods, scientific computing Excellent programming skills (e.g. Python, Julia, C++, etc.) with readiness to deepen your programming proficiency.\n\nStrong analytical and problem-solving skills.\n\nYou have a can-do mentality with no fear of getting your hands dirty when needed.\n\nYou have strong verbal and written communication skills in English.\n\nYou can work independently as well as in a team with well-developed communication skills.\n\nKnowledge of AI, machine learning techniques is a plus.\n\nExperience with CUDA, PyTorch, TensorFlow skills is a plus.\n\nExperience with fiber optic measurement principles and/or interferometry is a plus.\n\nApplicants should be eligible for NATO/Dutch security clearance.\n\nSecurity & Compliance:\nYou'll be working with clients in the defense and security sectors, obtaining a Certificate of No Objection issued by the AIVD (Dutch General Intelligence and Security Service) is mandatory. This means you will need to undergo a security screening.
