The Department of Physics and Astronomy (IFA), Aarhus University, Denmark (www.phys.au.dk) invites applications for a 2.5-year academic employee position with focus on establishing and maintaining trapped ion quantum technology setups. The work will partly be carried out in the newly established Quantum Technology Lab (QTL) and within the Ion Trap Group.

The position is open from 15 September 2025, or as soon as possible thereafter. 

Your profile

The candidates are expected to have experience in cold trapped ion research, and hence both have experience in ion trap and laser technology. We are seeking enthusiastic candidates with a keen interest in setting up a new teaching ion trap setup in QTL as well as participate in maintaining and running ion trap experiments within the Ion Trap Group. More specifically, the candidate should have a solid background in construction and operating rf ion traps, CW laser systems including control of output powers, polarization states, linewidths and frequencies, as well as an understanding of analog and digital electronics for experimental control. Relevant methodology includes UHV vacuum handling, rf circuity electronics, laser frequency stabilization using optical frequency combs, rubidium atomic clocks, and GPS synchronization.

A PhD degree in Physics or Engineering is an advantage, and applicants must be able to document relevant experience, as outlined above.

Who we are / The department
The Department of Physics and Astronomy is a department at the Faculty of Natural Sciences, Aarhus University, Denmark. The main objectives of the Department are to carry out research at the highest international level, to offer research based teaching at Bachelor of Science, Master of Science and PhD levels, and to exchange knowledge with other areas of society, e.g. by offering our expertise to industrial partners and the business world.

The Department is an attractive workplace for researchers, teachers, technicians, laboratory technicians and administrators and has a good study environment with many talented and active students at all levels. The research at the Department of Physics and Astronomy is of high quality, attracts significant international attention – in several fields the Department is within the world elite – and is characterized by many international collaborations with other high-ranking universities and research institutions around the world.
 

The successful candidate is offered:

• a working climate inviting lively, open and constructive discussion within and across different fields of research
• a working environment with teamwork, close working relations, and social activities
