TNO Delft – working at the heart of technology

Almost everything needs to be more efficient, powerful and – at the same time – smaller and cost-effective. At TNO’s Delft location, ‘Stieltjesweg’, this is just what excites our top scientists to go a step further in developing solutions for the most complex of questions. Here, we can offer you interesting research opportunities and a lively working environment in a broad and international market. Come join us and accelerate innovation!

Join us to bring groundbreaking research to actual application


It is all about the people at Stieltjesweg. We push the limits of technology in order to stimulate industry and enable scientific discovery in the fields of optics, opto-mechatronics, quantum technology, contamination control and space systems engineering. To perform at the forefront of innovation, we work on projects with colleagues from diverse backgrounds and areas of expertise.

As TNO, being the independent research organisation in the Netherlands, it’s our mission to provide the right answers. And to ask the right questions. By combining disciplines, we can tackle the most complex of questions. We never stop thinking...about what works and what can be improved. Everything changes, but when is change for the better? If you look through our eyes, you’ll see a future in which we can move around in safer, smarter and cleaner ways. Because with every innovation we contribute to a better tomorrow.

Fast and secure internet all over the globe? Real-time monitoring of pollution and carbon dioxide emissions from out of space? Look through the eyes of TNO and envision it!

A wide range of technologies

What’s so interesting about working at Stieltjesweg in Delft? TNO has a variety of unique locations and this is certainly one of them. With its state-of-the-art lab facilities, location on the Delft University of Technology campus and with 245 experts pushing the boundaries of technology, Stieltjesweg is a vibrant working environment.

This is where the Van Leeuwenhoek Laboratory (VLL) is located. Within the field of nanotechnology, VLL is one of the largest (cleanroom) research facilities in the Netherlands. This 6000 m2 laboratory – half of which is dedicated to class 100-1000 cleanroom facilities – is where we join forces with Delft University of Technology and external partners in order to create the extraordinary.

VLL is just one example of the state-of-the art facilities in which we carry out our innovative work. Stieltjesweg also houses a wide range of cutting-edge projects and research areas. We explore many different technical fields and aim to bring fundamental research to actual application, moving it up the ladder of technical readiness. This means that our people work on early stage research up to actual proof-of-concept or prototypes, putting ideas into practice.

Focusing on innovative markets

We focus on several attractive, innovative and vastly expanding markets.

In the Space & Science Instrumentation market, we focus on Earth observation, Astronomy - both ground and space based - and laser satellite communication.

In the Semiconductor Equipment market, we create the best semiconductor equipment of today, and explore all the possibilities of tomorrow, together with our partners (a.o. ASML, Carl Zeiss and Microsoft).

We aim to advance in these markets by using our specialist knowledge in the expertise areas of:
