Wissenschaftliche Mitarbeiterin oder Wissenschaftlicher Mitarbeiter (PostDoc, m/w/d) "Optomechanische Inertialsensoren”

Senior Research Scientist (PostDoc, m/f/d) “Opto-mechanical Inertial Sensors”

(Salary Scale 13 TV-L, 100 %)

The Institute for Gravitational Physics (IGP), Leibniz University Hannover, Germany invites applications for the position of a Senior Research Scientist (PostDoc, m/f/d) “Opto-mechanical Inertial Sensors” (Salary Scale 13 TV-L, 100 %) to be appointed at the earliest possible date. The position is limited to three years.

The applicant will join to a multi-disciplinary team at the Institute for Gravitational Physics (IGP) of the Leibniz University Hannover. The IGP is a world leading research center specializing in gravity, gravitational waves and laser interferometry. The project will be carried out in close cooperation with the recently founded Institute for Satellite Geodesy and Inertial Sensing of the German Aerospace Center (DLR-SI), which is located nearby the IGP.

The IGP has a significant track of outstanding contributions to the success of both the LISA Pathfinder (LPF) and GRACE Follow-On (Gravity Recovery and Climate Experiment) missions. With LPF and GRACE-FO, heterodyne interferometry has been proven as a feasible technology for some of the most ambitious metrology developments in the field of geodesy and gravity. Currently, our group is involved in the development of next generation opto-mechanical inertial sensors. Such an optical metrology system will enable the development of novel instruments such as gravimeters and gravity gradiometers with unprecedented precision, particularly on the low-frequency band, where current detectors are typically limited in terms of sensitivities. This instrument will be of great benefit for future geodesy applications that aim to improve on the gravity sensing capabilities, such as Next Generation Gravity Field Missions (NGGMs) and GOCE-type gradiometry missions.


We are seeking a Senior Optical Physicist or Engineer to join our team with proven experience in precision laser interferometry systems and/or opto-mechanical sensors. The successful candidate will provide support in the development of optical sensor designs, coatings, polishing methodologies and metrology techniques.

The long-term goal of the project is to build an engineering model of a compact inertial sensor as part of an opto-mechanical accelerometer for Next Generation Gravity Field Missions (NGGMs).


A successfully completed university degree is a prerequisite for the application. A PhD degree in Physics, Optical Technologies, Engineering or in a comparable field is expected. The candidate should have proven experience in precision laser interferometry and/or optomechanical sensors.

Furthermore, the ideal candidate will have in-depth experience with:

  • Design and handling of free beam and fiber-based optical setups
  • Polarization control
  • Basic electronics and control systems
  • Optical simulations
  • Finite element analysis
  • Object-oriented programming in C/C++
  • Data analysis, representation, and scientific writing
  • Good command of English is expected

Part-time employment can be arranged on request.

As an equal opportunities employer, Leibniz University Hannover intends to promote women and men. For this reason, suitably qualified women are specifically invited to apply.

Preference will be given to equally qualified applicants with disabilities.

Please submit your application including the usual documents (CV incl. publication list, letter of motivation, letter(s) of recommendation, university diplomas) by September 30th, 2020 in electronic form (as a single PDF-file) to
