Type of employment


The newly founded DLR Institute for Quantum Technologies in Ulm aims to develop precision instruments for space applications based on quantum technologies and to bring them to prototype maturity together with industry. It thus provides a bridge between fundamental research and industry. Together with the DLR-Institute for Satellite Geodesy and Inertial Sensing in Hannover and the Galileo Competence Center in Oberpfaffenhofen, the institute in Ulm has a pioneering role in these research and application fields. The research work of its four core departments Quantum Metrology, Quantum Information and Communication, Quantum Nanophysics and Quantum Control of Charged Matter Waves is complemented and supported by the three cross-sectional departments Quantum Engineering, Integration of Micro- and Nanosystems and Theoretical Quantum Physics. The institute is interdisciplinary in nature: Theoretical fundamental research and experimental tests meet engineering implementation.

We are looking for you for a position in the department "Quantum Metrology". Be part of our team that is bringing the first optical clock technology to the ISS space station within the COMPASSO project, demonstrating technologies for future generations of the European satellite navigation system Galileo in space. Here you will contribute to the development of an optical frequency reference based on Doppler-free spectroscopy of molecular iodine, which is being developed under the leadership of the DLR Institute for Quantum Technologies in collaboration with other DLR institutes, research institutes, universities and the space industry. You will bring your expertise to the creation of the design, the prototype phase and the activities during the build and verification. You will be actively involved in all stages of the process and contribute to the implementation of the project.

During the build-up phase of the Institute of Quantum Technologies, activities will initially be performed in Bremen. The position is – with work location Bremen.

Your tasks are:

  • You will build the engineering model of the optical frequency reference for the COMPASSO project with us.
  • You will lay out the mechanical and thermal design for space flight.
  • You will check the design for feasibility, mountability and completeness, also with respect to relevant standards for operation in space and on the Bartolomeo platform at the ISS.
  • You characterize the final implemented reference in the laboratory.
  • You prepare the implementation of the frequency reference as a flight model, which takes place in industry or at the DLR Galileo Competence Center in Oberpfaffenhofen.
  • You are part of a team of scientists and engineers.
  • You exchange scientific results with peers and compare and evaluate the results with alternative methods.

Your qualifications:

  • completed scientific university studies (master/diploma) in the field of physics, mechanical engineering or electrical engineering.
  • experience in design, development and characterization of laser optical setups, ideally frequency stable laser systems
  • experience in planning and evaluation of satellite missions
  • expertise in simulation, finite elements, design using computer CAD, thermal simulation, planning of measurements (Matlab, Inventor, ANSYS, Labview)
  • very good knowledge of English, both written and spoken
  • capability to work independently
  • enjoyment of teamwork with scientists
  • passion for innovative research
  • laboratory experience with laser optical experiments is of advantage
  • experience in the implementation of space projects is a plus
  • experience in simulation, finite elements, CAD design is desired

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
