Physikalisch-Technische Bundesanstalt (PTB)

Braunschweig, Germany

The Physikalisch-Technische Bundesanstalt (PTB) is the National Metrology Institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science.

In Department 4.3 “Quantum Optics and Unit of Length” of Division 4, we are looking for an

Experimental physicist (with a doctorate)

to join us as soon as possible.

The position is available on the basis of a 3-year fixed-term contract. An extension of the employment might be possible. You will be employed at our Braunschweig site.

Depending on your personal qualifications, the remuneration can reach up to remuneration group 14 TVöD Bund.

Your tasks:

The position comprise the development and application of a transportable optical lattice clock. The optical clock is used to measure geodetic differences in heights and to conduct international clock comparisons. You will further develop our optical clocks by working on the following research aspects:

  • Using our transportable lattice clock for clock comparisons and applications in geodesy at different locations
  • Realization of an optimized set-up with an uncertainty of a few 10^-18

Your profile:

  • You have successfully completed your university studies (German “Diplom” or Master’s); if possible, you have a doctor’s degree in physics
  • You have profound knowledge of quantum optics, laser cooling, laser spectroscopy or related subjects
  • You have expertise in atomic physics
