Internships & Graduation Projects

Leiden
40 hours
Flexible

At Nijssen, people from diverse backgrounds collaborate on smart, custom climate and refrigeration solutions. From plant science to refrigeration technology, from technicians to administrative staff: it's precisely this mix of knowledge and experience that makes our work so interesting. As a result, our company offers various opportunities for internships and graduation projects.

We'd be happy to work with you to find a project that aligns with your studies, interests, and talents. Perhaps your challenge lies in technology, sustainability, plant cultivation, process improvement, administration, or something entirely different. Do you have a fresh perspective and are eager to brainstorm, research, and contribute to solutions that truly matter? Then we'd love to get to know you.

At Nijssen, you'll receive guidance from experienced colleagues, have the space to ask questions, and get the chance to be part of a welcoming family business where technology, innovation, and collaboration are central.

Does this sound like a place where you'd like to learn and grow? Feel free to send us a message via hr@nijssen.com. We'd be happy to discuss a suitable internship or graduation project with you.
