Research Technician

DIFFER is the Dutch Institute for Fundamental Energy Research, one of the nine research institutes of the Netherlands Organisation for Scientific Research (NWO). The institute focuses on a multidisciplinary approach to energy research, combining physics, chemistry, engineering and materials science. DIFFER's research takes place in two main themes: Solar Fuels for the conversion and storage of renewable energy and Fusion Energy as a clean and unlimited source of energy. DIFFER develops and supports a national network on fundamental energy research and collaborates closely with the academic community and industrial partners.

Research Technician

At DIFFER we perform fundamental research on renewable energy. Are you interested in supporting our research team and extend the technical support capabilities within our Solar Fuels Facilities and Instrumentation group? We are seeking a research technician who will manage several optical laboratories and setups and who can assist the scientific staff.

Responsibilities and tasks: 

Your primary responsibility will be the operation and maintenance of our laser equipment in close contact with DIFFER scientists to support to their experiments. For example, you will assist daily for the maintenance and alignment of our frequency-tunable optical parametric oscillators (OPOs) and provide advice about the design and purchase of new optical setups and equipment. Depending on the workload, you may also be involved in specific tasks of a research project. Additionally, as research technician you have an important role regarding the safety of the lasers both in supporting the DIFFER laser safety officers as well as in the supervision of the safe operation of laser setups. Lastly, you will gradually take over the maintenance of our UV-Vis-NIR and FTIR spectrometers.


We seek enthusiastic candidates that are willing to work in an international and interdisciplinary team of physicists and chemists. The applicant should hold a relevant HBO degree, preferably in the fields of Applied Physics, Electrical Engineering, or Process Engineering, although different relevant qualifications will be considered. Prior working experience particularly in laser physics, laser and fibre optics, and optomechanics is a key requirement. Affinity with electronics, basic web-programming, and laser safety are highly appreciated. Very good verbal and written communication skills in English are mandatory.

Employment conditions: 

Our institute offers a first class and international research environment with various interdisciplinary but related research topics and projects. You will be employed by the NWO institute Foundation for a fixed period of two years. Your salary will be up to a maximum of 3,492 euro gross per month, depending on your level of experience. The salary is supplemented with a holiday allowance of 8 percent and an end-of-year bonus of 8.33 percent.

Such as conditions for teleworking, partly paid parental leave and the possibility to purchase and sell holiday leave. General information on working at NWO can also be found at the NWO website (

Further information: 

The 'NWO job interview code' applies to this position. At DIFFER we believe that a workforce diverse in gender, age and cultural background is key to performing excellent research. We therefore strongly encourage applications from women and minorities in general. In our institute physicists, chemists, engineers and other specialists work together in multidisciplinary teams to accelerate the transition to a sustainable society. To strengthen our committment to diversity, in January 2018 we formed a taskforce with the aim to design, implement, and monitor diversity and gender equality initiatives. These initiatives include a revision of the recruitment process, to prevent and where necessary mitigate implicit biases in the selection of candidates.
