The Dutch subsurface plays a major role in the energy transition. How? Take, for example, underground storage of renewable energy in former gas fields or the extraction of geothermal heat. All major energy and climate themes require access to more and more data with an increasing number of applications. As a senior developer at TNO, you will develop front-end and back-end services for the information needs of researchers, governments, and commercial parties. You can also focus on database technology. You decide, because we are looking for several senior developers with a passion for the latest technologies and a great interest in geodata!

What will be your role?

As a senior developer, you will contribute to TNO’s statutory duties in the field of data registration of the subsurface, such as for the Key Registry of the Subsurface and the Mining Act. In a scrum team, you will build the portals and services that help the Netherlands improve, including the BROloket. You will improve existing functionality, add visualization, for example, and continually develop new applications. Your range is very broad: from information systems to permit applications. Would you prefer to focus on databases? In that case, you will bridge the gap between relational technology and NoSQL for the migration of old and the development of new databases. 

Your home base is one of the Geological Survey of the Netherlands’ three GeoData & IT development teams. In your team, you will work closely with eight to ten colleagues, including developers, technical designers, and analysts. No matter who you ask, your colleagues will unanimously agree: you will be joining a great team with people who like buckle down and help each other. Your scrum team is self-managing, and you actively seek each other out with questions and ideas. And laughter is definitely part of the deal!
