GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt operates one of the leading particle accelerators for science. In the next few years, the new FAIR ( F acility for A ntiproton and I on R esearch) 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 Experiment Electronics department supports science experiments and projects at GSI/FAIR in all electronics-related tasks. Our strength is detector readout, data acquisition, data analysis, and the monitoring and control of single detectors, and complex large scale detector systems. We support scientists in planning, implementation and application of novel technologies, including those that go beyond state-of-the-art systems.

To keep pace with the ever-increasing demand of the experiments for innovative developments, we are looking for an

ASIC (Digital) Design Engineer

Posting-ID: 25.131-6220

The ASIC design group is engaged in the design, subsequent test and characterization of highly complex mixed-signal ASICs. Therefor a powerful CAD environment for design and simulation, a modern machinery under clean room conditions and a well-equipped test laboratory is available. Furthermore, the working group is embedded in the team of the experiment electronics department with about 30 highly skilled and qualified people. We offer exceptional expertise in analog and digital electronics.

Your tasks:

Participation on the development of concepts for ASIC based detector readout architecturesDevelopment of mixed-signal ASICs for the readout of particle detectors in high energy physics in collaboration with the design teamIn particular independent and self-dependent development of digital and mixed signal circuits bases on VHDL descriptionTest and characterization of prototypes in the laboratoryWork in our clean room (Die- and Wire Bonding)Support and assistance for our experiment groups.

Your profile:
