Job description

You will become part of a team working on the development of different material platforms for Integrated Photonics. In particular, this position deals with the development of wafer-level characterization structures to improve both fabrication process (i.e., uniformity, reproducibility, yield) as well as validation of a PDK of integrated photonics building blocks.

Tasks in the project include designing correct tests structures as well as algorithms based on statistical analysis and potentially machine learning to first, feed back to both the fabrication process as well as the PDK development and eventually predict the performance based on a set of measured data. You will work closely with a Post-doc in the same project as well as with a consortium of industrial partners.


University of Twente (UT)


  • An enthusiastic and highly motivated research attitude.
  • A master’s degree in engineering physics, electrical engineering, materials engineering/science or photonics engineering, with interest in design, microfabrication and characterization.
  • And a background in cleanroom microfabrication deposition of optical materials, and design/simulation of optical and/or electronic devices is a plus.
  • You have a creative mindset and excellent analytical and communication skills.
  • You have a good team spirit and like to work in an interdisciplinary and internationally oriented environment.
  • You are fluent in English, spoken and written.
  • Female candidates and members of minority groups are equally encouraged to apply as we strive for working in a well-balanced inclusive team.

Conditions of employment

  • A full-time position for four years, with a qualifier in the first year.
  • Your salary and associated conditions are in accordance with the collective labour agreement for Dutch universities (CAO-NU).
  • You will receive a gross monthly salary ranging from € 2.770,- (first year) to € 3.539,- (fourth year).
  • There are excellent benefits including a holiday allowance of 8% of the gross annual salary, an end-of-year bonus of 8.3%, and a solid pension scheme.
  • A minimum of 232 leave hours in case of full-time employment based on a formal workweek of 38 hours. A full-time employment in practice means 40 hours a week, therefore resulting in 96 extra leave hours on an annual basis.
  • Free access to sports facilities on campus.
  • You will have a training programme as part of the Twente Graduate School of the University of Twente where you and your supervisors will determine a plan for a suitable education and supervision.


The Integrated Optical Systems group consists in average of 6-7 PhD students, 2-3 MSc students, 2-3 post-docs and several staff members. Our vision is to develop novel materials, devices and integration technologies for Integrated Photonics to solve societal problems. We are part of the MESA+ Institute for Nanotechnology, which offers advanced characterization and fabrication tools at the nanoscale, as well as a stimulating scientific environment with more than 250 PhD students working on various aspects of nanoscience and technology.

In addition, we are part of a group of around 80 researchers that explore, within the research cluster Applied Nanophotonics (ANP), multiple aspects of modern photonics. These include technologies such as the development of materials, integration technologies, photonic assembly, packaging, and laser processing for applications including quantum optics, control of light scattering, photonics crystals, XUV optics, biomedical imaging, and sensing.
