Tijdelijk contract / Tijdelijke opdracht


NeCEN is looking for a highly talented scientist experienced in cryo-electron microscopy who would like to contribute to the performance of an advanced cryo-EM centre at a world-class level.

You will maintain optimal equipment performance and collect high-quality data as part of a team, with the aim of providing optimal service to NeCEN's users. You will be primarily responsible for helping users with sample loading, alignment, and data acquisition on two Titan Krios microscopes, a Talos L120C TEM, an Aquilos Cryo-FIB (cryo-lamellae preparation for tomography) and cryo-CLEM setup. Additionally, EM scientists at NeCEN are offered to perform collaborative research and technical development (approx. 20% of the time) to help ensure NeCEN remains at the forefront of electron microscopy. The key responsibilities consists out of:

  • Together with the other EM scientists, take care of the advanced cryo-EM microscope equipment with their ancillaries;
  • Ship, prepare, and load samples, align/tune microscopes prior to data collection, setup and oversee image acquisition, and evaluate data quality;
  • Communicate experimental details to users, assist with data analysis in the context of collaborative projects and write experimental methods for resulting publications;
  • Maintain ancillary equipment (cryo-plunger, glow discharger, etc.) and occasionally order consumables;
  • Explore and implement improved data-collection strategies, including testing new software and hardware;
  • Maintain accurate logs to monitor microscope performance, experimental conditions, usage, scheduling, and billing;
  • Consult with other cryo-EM experts in the region and internationally by participating in cryo-EM meetings and workshops;
  • Write clear documentation, establish facility procedures, and perform light administrative duties;
  • Willingness to occasionally work evenings and/or weekends to ensure maximal use of microscopes.


  • MSc or PhD in the fields of biology, chemistry, or physics;
  • Previous experience in cryo-electron microscopy and/or cryo-FIB is highly valued;
  • Previous experience in maintaining microscopy equipment and working in a lab would be an advantage;
  • A keen interest in contributing to and running an international centre for advanced cryo-electron microscopy;
  • Good communication skills;
  • Service oriented approach;
  • Fluent witten and spoken English.
