Engineer (22-333-QUEST) Tuesday, 4. October 2022

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. The QUEST Institute for Experimental Quantum Metrology is a joint institution of Leibniz University Hannover (LUH) and PTB Braunschweig.

With a starting date as soon as possible, PTB is looking for a candidate to fill the following position at the QUEST Institute for a fixed term ending 30 September 2024:

The place of work is Hanover, Germany.


Your tasks:

Within the Research Building at the Hannover Institute of Technology (HITec), PTB operates a laboratory for the distribution of high-precision optical frequencies and radio frequencies using an optical frequency comb stabilized to a reference frequency provided by PTB via optical fiber. HITec researchers use these frequencies to conduct experiments relating to optical clocks, long-baseline atom interferometry and quantum computing, as well as for geodetic studies of global navigation satellite systems (GNSSs). Your task will be to take the laboratory into operation and to establish the infrastructure for conducting measurements and comparisons. Your work will focus on the following key elements:

  • Assisting with the building of the fiber length stabilization system between HITec and PTB
  • Building and characterizing fiber-based and free-space optical laboratory systems, e.g. for phase-stabilized optical frequency transfers, for the optical phase stabilization of lasers, and for the low-noise detection of beat frequency
  • Developing, implementing and characterizing both analog and digital (FPGA-based) RF signal processing of the RF beat signals generated by the frequency comb
  • Building distribution systems for the generated radio frequency signals
  • Automated experiment monitoring, data analysis, and developing concepts for enhancing the fail-safeness of the system
  • Jointly developing solutions to satisfy the requirements specified by researchers for their experiments
  • Performing and assessing measurements and documenting the measurement results


Your profile:

  • You have completed your university studies (Bachelor’s degree, German FH-Diplom or similar qualification) with a very good grade in electrical engineering, communication engineering, mechanical engineering, optics, high-frequency engineering or in a comparable field

  • Ideally, you are skilled in programming FPGAs
  • You have programming experience in at least one contemporary programming language (preferably Python)
  • You exhibit good experimental and organizational skills and are able to work in an autonomous and well-structured manner
  • You are a strong team player with excellent communication skills
  • You have a good oral and written command of both German and English
  • You are physically able to stand for long periods when performing tuning and adjustment work


We offer:

  • Remuneration in accordance with the Collective Bargaining Agreement for the Public Service covering federal employees (Tarifvertrag öffentlicher Dienst Bund – TVöD)·
  • A public sector pension scheme (VBL)
  • Compatibility of work and family life (flexible working hours and part-time schemes)
  • 30 days’ paid annual leave
  • Various workplace health and wellness options·
  • Various basic and advanced training opportunities
