Description

Your (space) mission As a Scientist or Mechanical Engineer at cosine, you will contribute to cutting-edge technologies that enable space exploration, Earth observation, and advanced scientific research. Whether your expertise lies in physics, mechanics, electronics, optics, thermal engineering, or systems development, you will work alongside multidisciplinary teams to solve complex technical challenges and transform innovative ideas into real-world instruments and systems. At cosine, we combine scientific excellence with hands-on engineering. Our teams develop high-performance technologies for international space missions, scientific facilities, and industrial applications. Depending on your background and interests, you will be working on projects that range from concept development and modelling to testing, integration, and validation. We are always interested in meeting talented MSc and PhD graduates who are eager to push technological boundaries and make a tangible impact on the future of science and space exploration. Potential opportunities include: Scientist Engineer Thermo-Mechanical Develop and analyse thermal and mechanical solutions for high-performance instruments operating in challenging environments. You will contribute to the design, modelling, testing, and qualification of systems that must perform reliably in space and other demanding applications. Scientist Engineer Electronics / Avionics Design, develop, and validate electronic subsystems that form the backbone of advanced space instrumentation. Your work may involve embedded electronics, avionics architectures, hardware verification, and system integration, contributing directly to mission-critical technologies. Scientist Engineer Silicon Pore Optics Support the development of next-generation X-ray optics based on Silicon Pore Optics technology. You will design and execute experiments, analyse measurement data, work with precision assembly processes, and contribute to technologies that enable future space telescopes and advanced scientific instrumentation. Mechanical Engineer Translate complex technical requirements into innovative mechanical designs and practical engineering solutions. You will work across the full development cycle, from concept generation and detailed design to manufacturing support, testing, and customer-facing project activities. Tasks & responsibilities Your profile We are looking for candidates with the following qualifications: MSc or PhD degree in Physics, Mechanical Engineering, Aerospace Engineering, Electrical Engineering, Applied Physics, or a related technical discipline Strong analytical and problem-solving skills combined with a hands-on engineering mindset Affinity with complex multidisciplinary systems and technology development Experience through academic research projects, industrial R&D, or relevant engineering activities Ability to communicate effectively in English within an international environment Curiosity, initiative, and motivation to contribute to innovative technologies for space and science Residing within commuting distance of Sassenheim, the Netherlands, or willing to relocate What we offer At cosine, we highly value our employees, and we will support your professional and personal development. We also provide our employees with: A unique, international working environment at the intersection of physics and engineering The opportunity to deliver end-to-end solutions in autonomous project teams, in close collaboration with customers A competitive salary based on the extend of relevant experience and seniority of the position 27 days of annual leave (based on full-time employment) Annual bonus based on personal and company performance Hybrid working options, including the possibility to work partially from home Company bicycle and fitness plans A personal development budget About cosine cosine transforms high-stakes measurement challenges into scalable, real-world solutions. What sets cosine apart is its integrated approach, linking insight, science, and engineering to deliver solutions that work in the real world, enable science and make an impact for humanity. Backed by over 25 years of heritage, expertise and deep systems thinking, cosine guides partners from defining the real need to deploying reliable, precision-built technologies that enable progress across space and planet. What makes cosine a unique place to work is that your work goes end-to-end: from concept and design to building, testing, and delivering hardware that actually flies in space. You work in small, highly skilled teams where you have real ownership and impact, alongside experts in optics, physics, nanofabrication, and systems engineering.
