Photonics engineer / experimental physicist for optical sensors (f/m/x)
Job Description
Req ID:  4634
Place of work:  Ulm
Starting date:  01.07.2026
Career level:  Experienced professionals
Type of employment:  Part time, Full-time
Duration of contract:  zunächst befristet auf 3 Jahre

Remuneration: Remuneration is in accordance with the Collective Agreement for the Public Sector - Federal Government (TVöD-Bund)

Enter the fascinating world of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt e. V.; DLR) and help shape the future through research and innovation! We offer an exciting and inspiring working environment driven by the expertise and curiosity of our 12,000 employees from 100 nations and our unique infrastructure. Together, we develop sustainable technologies and thus contribute to finding solutions to global challenges. Would you like to join us in addressing this major future challenge? Then this is your place!

At the DLR Institute of Quantum Technologies in Ulm, we develop precision instruments for space applications based on quantum technologies and bring them to prototype maturity together with industry. In addition, we are driving forward the transfer to aeronautics, digitalisation, energy, security and transport. Our work is highly interdisciplinary: theoretical research and experimental investigations meet engineering implementation.

What to expect
The Quantum Metrology department (QT-QME) develops highly precise optical and opto-electronic measurement systems for applications in navigation, Earth observation and scientific missions. Laser-based technologies such as interferometric sensors, optical references and fiber-optic systems enable measurements with extremely high precision.
In this position you will contribute to the development of novel laser-interferometric acceleration sensors for next-generation inertial navigation systems. These sensors enable reliable navigation in environments where GPS signals are unavailable or disturbed. Your work will focus on the experimental implementation, characterization and miniaturization of quantum-optical metrology systems as well as the development of interferometric and laser-based measurement techniques.
Your tasks

  • You are responsible for setting up, adjusting and characterising optical and interferometric experiments.
  • You develop and optimise laser-based measurement systems and optical references.
  • You set up and analyse fibre optic systems.
  • You work on waveguides and photonic integrated circuit structures.
  • You carry out and analyse precise optical measurements and spectroscopy experiments.
  • You develop experimental measurement methods and data analysis procedures.
  • You automate measurement setups as well as data acquisition and evaluation, e.g. Python.
  • You are part of a team that works together to master electronics, laser development and systems engineering.Automation of laboratory experiments and data acquisition/analysis (e.g. Python).

Your profile

  • completed scientific university degree (Master's/Diploma) in *natural sciences (e.g. physics) or *engineering (e.g. aerospace engineering, mechatronics, electrical engineering) or other degree programmes relevant to the position
  • extensive experience in the development of optical metrology systems and optical technologies for space applications,
  • in-depth expertise in systems engineering of space projects
  • PhD in engineering or experimental physics
  • practical research experience in the field of optical laser metrology, e.g. acquired through studies or a doctorate or other proven research activities
  • In-depth expertise in systems engineering of space projects, design and analysis of fibre optic systems, work on waveguides and photonic integrated circuit structures and performance and evaluation of precise optical measurements and spectroscopy experiments
  • Development of experimental measurement methods and data analysis procedure

Remuneration is based on the German TVöD E14 (Collective Agreement for the Public Service) according to qualification and assigned tasks.

We offer

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.

We look forward to getting to know you!
