Scientific Software Engineer | Delft

Quantum technology is one of the emerging and most promising technologies of our time. Within TNO’s Quantum Technology department, research is conducted in three core areas of quantum: quantum computing, quantum communication, and quantum sensing. You will work within this department and contribute to projects that are carried out both directly for clients and in close collaboration with partners within the Dutch and European quantum ecosystem.

At TNO, we apply leading scientific knowledge to develop new technological solutions and applications. Our work focuses on designing and building systems that make use of quantum properties, bridging the gap between fundamental research and practical applications through test setups, demonstrators, and product development. Software forms an essential foundation for experiments in quantum technology. As quantum systems become more complex, robust software architectures and further simplification and automation of experiments are crucial to enable growth. To further shape this development, the Quantum Technology department is looking for a Scientific Software Engineer. Does this appeal to you? Then come and strengthen our quantum team.

In this role, you will design, write, and maintain software together with other Scientific Software Engineers and/or domain experts. You will work on multiple projects in which you help colleagues with high-quality software. Within these projects, you will work on various topics related to control and analysis software for quantum computers, ranging from capturing experiments in software and writing instrument drivers to maintaining CI pipelines and performing data analysis and visualization. You will apply various technologies, including Python and GitLab CI. With your software, you will enable technical progress and make a major positive impact on the team. In short, you will never be bored and will have the opportunity to leave your mark on our department and on quantum technology in general. You will have room to learn new technologies and work on a wide range of interesting topics and challenges.
