Scientific Software Engineer For Heterogeneous Computing at Deutsches Elektronen-Synchrotron DESY
Hamburg, Germany
Summary
👤
Senior🎓
Top SchoolChristian Wessel is a scientific software engineer and experimental physicist with 11 years of experience building high-performance, heterogeneous computing solutions for particle- and space-detector projects. Based in Hamburg, he combines deep expertise in C++ and Python with hands-on detector R&D from his PhD and postdoc work on Belle II, including real-time DATCON systems and Hough-transform tracking for pixel and strip detectors. At DESY he now focuses on optimizing memory and compute across diverse architectures while co-convener duties at the HEP Software Foundation keep him shaping community reconstruction and trigger software. He also brings practical aerospace experience from satellite dynamics and control work, and routinely applies ML tooling (PyTorch, TensorFlow) to petabyte-scale analysis challenges. Notably, he balances low-level performance tuning with algorithm development and collaborative code stewardship across large international experiments.
