In HollandPTC we have facilities to conduct radiobiological research with protons. We have a biological lab for pro-cessing cells before and after proton irradiation, and we are currently setting up a lab for animal testing. Researchers from Erasmus MC, LUMC, Delft University of Technology, and other organisations use our research facilities.

As our Biological Technician you will be in charge of the biological lab. You will be the designated point of contact for researchers and you will provide technical support for the set up and execution of their experiments. You will be responsible for the necessary laboratory facilities and the correct procedures, and you will ensure that researchers can use these resources as effectively as possible. Moreover, you will be responsible for the structuring, scheduling, and safety of the labs. This includes working with genetically modified organisms (GMOs). In addition, you will be involved in the management of the animal testing lab. You will be a member of the R&D beamline team, which is managed by our beamline scientist. She is responsible for the proton irradiation in the R&D bunker. You will work with the research office to schedule projects and you will coordinate the experiments with the beamline scientist, R&D physics technician and the researchers involved.


Where will you be working?

HollandPTC is an independent outpatient clinic for proton therapy in Delft. The centre employs about 70 permanent staff who work in the fields of healthcare, physics, research and development, and operations management. Furthermore, HollandPTC has clinical physicians, physicists and researchers who also work for other institutes or organisations. Together we serve the needs of our patients and we conduct research. The centre has 2 proton gantries with in-room CT imaging and a treatment room for the irradiation of eye tumors. We also have cutting-edge imaging equipment, including a dual-energy CT, a 3T MRI and a PET/CT. In addition, we have an R&D beamline bunker and several labs for research. In our laboratories we primarily carry out preparatory work for experiments with the beamline.  

The R&D department

There are currently 7 people working in the Research and Development department: a department head, a beamline scientist, a clinical R&D coordinator, a research programme R&D coordinator, a staff advisor and a man-agement assistant. The team will soon be expanded with an R&D physics technician and a scientific programmer. In addition, other researchers and students are present in the department on a daily basis. We expect to expand to some 50 PhD students over the coming 3 years.  

Job description

You will:
  • provide advice to researchers and support them in setting up and conducting their radiobiological experiments.
  • draw up and maintain procedures and protocols for working in the biological lab, including working safely with GMOs.

  • provide researchers with information on our house rules and safety regulations in our labs.
  • supervise cleanliness and safety within the radiobiological research labs.
  • coordinate, register, and maintain all materials and equipment in the radiobiological research labs, and order stocks.
  • share your knowledge and experience with HollandPTC colleagues.
The beamline scientist will be your operational manager, and you will report to the head of Research and Education, who is also the R&D department head.  

Qualifications and skills

You will have:
  • a biology and medical laboratory research degree from a university of applied sciences
  • at least 5 years experience with cell cultures and cell biology techniques and with working with GMOs (MLII)
  • experience in drawing up procedures and protocols for working in a biological lab
  • experience with animal research and radiation protection is an advantage
In addition, you are service-oriented, good at organising and collaborating, pro-active and a good sparring partner. You have strong communication skills and are fluent in Dutch and English (both verbally and in writing). The working language in the R&D department is English.
