Job description

Your (space) mission

As an Intern at cosine, you will contribute to cutting‑edge technologies that enable space exploration, Earth observation, and advanced scientific research. Rather than working on theoretical exercises, you will become part of a multidisciplinary team developing real instruments and systems for international space missions and high‑tech applications.

At cosine, we combine scientific excellence with hands‑on engineering. During your internship or graduation project, you will work alongside experienced scientists and engineers who are passionate about solving complex technical challenges. You will have the opportunity to take ownership of a meaningful project, develop new skills, and see how your work contributes to innovative technologies used in space and science.

We are always interested in meeting talented BSc, MSc, and PhD students who are eager to apply their knowledge to real‑world challenges and help shape the next generation of scientific and space technologies.

Potential opportunities

• Thermal & Mechanical Engineering – support the design, modelling, testing, and validation of high‑performance mechanical and thermal systems for demanding space and scientific applications.
• Electronics & Avionics Engineering – contribute to the development and verification of advanced electronic subsystems, embedded solutions, and avionics architectures used in innovative space instruments.
• Optics & Experimental Physics – participate in the development, testing, and characterisation of advanced optical systems and sensors, including technologies used in space telescopes and scientific instruments.
• Mechanical Design Engineering – assist in transforming technical requirements into practical engineering solutions, supporting activities ranging from concept development and detailed design to prototyping and testing.
• Systems Engineering & Instrument Development – work at the interface between disciplines, supporting the integration, verification, and performance evaluation of complex scientific instruments and systems.

Your profile

• Currently pursuing a BSc, 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.
• Hands‑on attitude and enthusiasm for technology development.
• Interest in multidisciplinary engineering and scientific projects.
• Ability to communicate effectively in English within an international environment.
• Curiosity, initiative, and motivation to learn and contribute.
• Residing within commuting distance of Sassenheim, the Netherlands, or willing to relocate for the duration of the internship.
