Physicist or Computer Scientist (m/f/d)

GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt operates one of the leading particle accelerators for science. In the next few years, the new FAIR (Facility for Antiproton and Ion Research) one of the world's largest research projects, will be built in international cooperation. GSI and FAIR offer the opportunity to work together in this international environment with a team of employees committed to ensuring each day to conduct world-class science.


The CBM (Compressed Baryonic Matter) experiment is one of the major experiments to be conducted at this new facility. CBM will investigate strongly interacting matter by measuring heavy-ion collisions, with the ambitious aim to achieve very high interaction rates. The experimental concept foresees real-time data selection in software, which requires highly performant and efficient algorithms for event reconstruction.


For the CBM department at GSI, we seek at the nearest possible point in time a


Physicist or Computer Scientist (m/f/d)

Posting ID: 5112-20.13



We expect:

The successful applicant is expected to take a leading role in firmware development within the FPGA-based CBM readout framework. This encompasses not only firmware quality assurance, but also requires a conceptual understanding of the CBM DAQ architecture. As such, the candidate will be part of the CBM data acquisition group at GSI.


The firmware development in form of IP-blocks written in VHDL for Xilinx FPGAs is handled by collaborating CBM groups at various local and remote sites. In particular, a global firmware development process needs to be implemented, which will allow to enforce best coding practices and to generate design documentation.



Your profile:

From the applicant, we expect a PhD in physics or computer science, or an equivalent degree at the time of recruitment. Experience in experimental heavy-ion or hadron physics, detector readout and in particular FPGA firmware development is expected. Applicants should have experience with accelerator driven experiments. Fluent English is mandatory, German is a plus. You are a team player who can work on projects in an international environment. Methodically, you can detect and propose fixes to firmware defects and malfunctions.



We offer:

We offer a challenging position at the forefront of nowadays technology, in the context of an international collaboration of about 400 members. The position is initially limited until December 2023.


Salary is equivalent to that for public employees as specified in the collective agreement for public employees (TVöD Bund).


GSI supports the vocational development of women. Therefore, women are especially encouraged to apply for the position.


Handicapped persons will be preferentially considered when equally qualified.
