Mateusz Fila
Software Engineer at CERN
Switzerland
Summary
🤩
Rockstar🎓
Top SchoolMateusz Fila is a research software engineer based in Switzerland with six years of experience applying C++, Python, and Julia to high-energy and nuclear physics problems. Currently at CERN working on heterogeneous computing R&D, he brings a strong blend of scientific computing and pragmatic software engineering—CI/CD, containerization, unit testing—that he introduced to teams during his PhD at the University of Warsaw. He built production-grade systems such as an OPC UA-based SCADA Detector Control System and led development of a ROOT-based data reconstruction framework used in experiments. Comfortable with system and network administration, he pairs low-level performance profiling with automation to move research code into reliable production workflows. Notably, he has hands-on experience coordinating small teams and shipping documentation-driven tooling (Doxygen/Sphinx) alongside core software.
