Faculty of Physics and Astronomy :
Chair of Experimental Physics 1 - Hadron Physics
In order to fill a fixed-term position in full-time (39.83 hours/week = 100%) starting on 01.03.2026, we are looking for a
Postdoctoral Reseacher (m/f/x): hardware development and integration for the LHCb experiment, 39,83 hrs/week
The LHCb experiment at CERN focuses on precision studies of heavy-flavour physics and hadron spectroscopy. As part of its Upgrade II program for operation at the High-Luminosity LHC, LHCb is developing the Mighty Tracker, a new downstream tracking detector that combines an inner pixel region with an outer scintillating-fibre (SciFi) tracker. The fibre tracker will employ long, radiation-hard fibre mats read out by silicon photomultipliers (SiPMs) and a new generation of front-end electronics based on the PACIFIC++ ASIC, providing precise timing and amplitude information at high rates. The project involves extensive hardware, electronics, and system-integration development, including fibre module production, cold-box mechanics, SiPM and ASIC characterization, and DAQ interface testing — areas, among which Ruhr University Bochum will play a leading role.
Your task involves close collaboration with partner institutes in Dortmund, Aachen, Freiburg, and Heidelberg (Germany), as well as EPFL (Switzerland) and ICCUB (Spain) within the LHCb Mighty Tracker project. You will work in an active, international research environment with opportunities for teaching, supervising students, and contributing to detector R&D at the forefront of high-energy physics.

- Programming (ideally Python, C++, at least one of the two).
- Experience with electronics development, data acquisition, and system integration.
- Ideally experience with SiPM readout.
We offer:
- A full-time position at TV-L E13, with level and step commensurate with experience.
- Workplace located in Bochum, Germany — a dynamic university city of about 100,000 residents, close to Düsseldorf, Dortmund, and the Sauerland nature reserve.
- Regular business trips to CERN for detector integration, testing, and project meetings.
Further information:
The position is salaried and based on the collective agreement of the Länder (TV-L). If the personal and collective agreement requirements are met, the employee will receive pay grade E13 TV-L.

The Staff Council has the right to participate in all selection interviews. At the request of a candidate (m/f/x), it will ensure its participation in the entire procedure. Please contact wpr@rub.de.
The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is Ruhr-Universität Bochum’s declared aim.
The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
