Geneva, Geneva, Switzerland
I will complete my mission at CERN in August 2026 and am currently exploring new opportunities in the French-speaking region of Switzerland (Romandy), particularly around Geneva and Lausanne. Over the past several years, I have worked as a Power Electronics Engineer in highly demanding, international environments, contributing to large-scale projects for the High Luminosity LHC. My experience includes power converter design, control systems, hardware validation, and reliability studies in complex and high-tech settings. I am fluent in English and Portuguese, and I work comfortably in French in professional contexts, within multilingual and multicultural teams. I am especially interested in roles where I can contribute to innovative engineering projects and bring value through both technical expertise and collaborative work. I would be glad to connect with professionals and organizations in the region. Feel free to reach out if you think there could be a good match or simply to exchange ideas.
• Validated the digital control systems for the Inner Triplet decoupling project using Hardware-in-the-Loop (HIL) testing. • Served as section representative, reviewing and validating an optocoupler-isolated gate-driver PCB for 50 krad radiation environments. • Led the analysis of earth leakage current and ground fault protection for the HL-LHC Inner Triplet power converters. • Designed and validated two high-precision four-quadrant power converters for the HiLumi LHC particle accelerator: HL-LHC2KA-10V (budget: 6.2 MCHF), HL-LHC600A-10V (budget: 1.3 MCHF): □ Achieved Class B EMC compliance through input filter design, PCB layout improvements and cabling optimization. □ Defined technical specifications, functional testing protocols, and manufacturing test procedures. □ Developed a time-efficient tool to design and optimize multi-loop control systems across the converter, including outer voltage control, Four-Quadrant Linear Stage (4QLS) current control, and Phase-Shifted Full Bridge (PSFB) control. □ Designed the peak current control strategy for the Phase-Shifted Full Bridge (PSFB), including microcontroller selection and parasitic-aware control design; Upgraded gate drivers to an isolated IGBT gate-drive architecture.
□ Designed 15 power converter PCBs in compliance with HiLumi requirements and CE standards. □ Designed magnet protection systems for superconducting loads, including: - Two redundant and modular crowbars using thyristor and diode technologies. - Diode failure monitoring circuit. - Electro-thermal design tools for busbar resistors and heatsinks. - Custom thyristor gate driver ensuring reliable performance and compliance with device specifications. - Led the tendering process for a 160 kCHF project, including technical specifications, supplier selection, contract drafting, and production follow-up. □ Developed novel methodologies to evaluate the operational limits of Four-Quadrant Linear Stage (4QLS) topologie for superconducting magnet applications.
