Job Description Introduction: You will lead hands-on research and development activities for the FCC-ee experimental program, focusing on beam-induced backgrounds, machine–detector interface studies, and detector optimisation to achieve the desired systematic uncertainties in precision measurements at the Z pole. The role combines technical leadership with active involvement in simulation, detector development, computing, and experimental validation to advance the design and performance of future FCC detectors. Functions: Carry out and supervise research and development activities on the experimental environment of the future FCC electron–positron collider, with emphasis on beam-induced backgrounds (BIB) and their impact on detector performance, via the integration of realistic background conditions into detector simulation and data reconstruction workflows. Develop scalable workflows and software infrastructure ensuring optimal use of computing resources, to run large-scale and detailed beam-induced background simulations. Interpret the results of these simulations to quantify background sources originating from the accelerator, assess their effects on particle detectors, readout strategies and data quality, and design and study strategies to mitigate these backgrounds in close collaboration with accelerator experts and detector designers. Develop methods to determine key limiting parameters directly from experimental data, towards enabling high-precision physics measurements at FCC-ee, including the definition of requirements for detector alignment, stability, and calibration needed to reach the targeted measurement precision. Contribute to the design and development of FCC-ee detector technologies, including hands-on work on prototypes, laboratory measurements and test-beam experiments, fostering collaboration between physicists, engineers, and software specialists. Present results in internal meetings, international workshops, and scientific conferences,
