Karlsruhe Institute of Technology (KIT) – The Research University in the Helmholtz Association creates and imparts knowledge for the society and the environment. It is our goal to make significant contributions to mastering the global challenges of mankind in the fields of energy, mobility, and information. For this, about 10,000 employees of KIT cooperate in a broad range of disciplines in research, academic education, and innovation.

We are looking for the Institute for Astroparticle Physics (IAP) from 01.10.2025, limited for 3,5 years, for a

Physicist or Electrical engineer (f/m/d) 65 % part-time

To strengthen our KATRIN++ team, we are looking for motivated and dedicated early-career scientists (f/m/d) who are eager to join us in developing the next-generation experiment for the direct determination of the neutrino mass. Our work lies at the intersection of fundamental research and cutting-edge technology. We particularly welcome creative minds who enjoy hands-on work in the laboratory and are driven by curiosity and commitment to advance state-of-the-art experimental methods.

Job description

• The focus of your research will be the characterization of Metallic Magnetic Calorimeters (MMCs) and other quantum sensors in external magnetic fields (up to 50 mT)
• You will independently design experimental setups for a 10 mK dilution refrigerator, perform measurements , and analyze the resulting data
• In addition, you will model detector performance (timing an energy resolution), compare simulations with experimental data, and extrapolate the sensitivity to the neutrino mass in the context of potential quantum sensor sensor array using a tritium source like at KATRIN
• Participation in teaching and outreach activities is expected

There is the possibility of pursuing a doctorate in addition to academic work.

Personal qualification

• You have a master's degree in physics or electrical engineering
• Strong expertise in the field of quantum mechanics (mK) and quantum sensors is desirable

Become a member of staff of the only German University of Excellence that conducts large-scale research on the national level. Work under excellent working conditions in an international environment and be active in research and academic education for our future. Benefit from specific training when starting your job and from a wide range of further qualification offers. Use our flexible working time models (flexitime, work from home), our sports and leisure offers, as well as our child and holiday care services. We also pay a share of EUR 25/month in the Job Ticket Baden-Württemberg. Enjoy a large variety of dishes, snacks, and beverages at our canteens.

We prefer to balance the number of employees (f/m/d). Therefore we kindly ask female applicants to apply for this job.

Recognized severely disabled persons will be preferred if they are equally qualified.

Please apply until 25.07.2025 using the vacancy number 252/2025 to Ms Silvia Ratzel, Karlsruhe Institute of Technology (KIT), Human Resources, Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany.
