Software Engineer - High-Performance Computing (EP-SFT-2026-137-LD)

Introduction

This role focuses on improving and evolving software developed in the EP-SFT group such as Geant4 and ROOT , two core software frameworks used for particle physics simulation and data analysis at CERN and laboratories worldwide. The position involves optimising and redesigning key components to run efficiently on modern high-performance computing systems, with a strong emphasis on GPU acceleration and large-scale parallel processing. Responsibilities include contributing to next-generation technologies such as AdePT for GPU-based particle transport, enhancing performance for exabyte-scale data processing, and developing tools for profiling, testing, and validation. Working at the intersection of HPC, C++ software engineering, and experimental physics, the role directly supports future research initiatives including the High-Luminosity LHC and the Future Circular Collider.
