JobsCloseBy Editorial Insights

CERN seeks a Test Engineer for Power Electronics to advance development and full characterization of radiation- and magnetic-field-tolerant DCDC converters for LHC detectors. You will design and upgrade test setups, improve Python-based control software, and perform electrical and radiation tests across campaigns. The ideal candidate has hands-on lab instrument experience, familiarity with real-time systems, soldering skills, and strong technical writing; PCB design and power electronics knowledge are a plus; Python or MATLAB proficiency is expected. Eligibility requires CERN Member State nationality, up to two years post-graduation, and a Bachelor's or Master's degree, no PhD. Onsite Geneva, 24 months; tips: tailor CV to real-time testing, web-based results logging, and concise documentation.

Job Description

In this role, you will contribute to the development and full characterisation cycle of radiation- and magnetic-field-tolerant DCDC converters powering the LHC experiments (ATLAS, CMS, ALICE, and LHCb). You will design and upgrade complex test setups, enhance control and monitoring software (Python), and perform electrical and radiation tolerance testing to ensure reliable large-scale deployment.

Your responsibilities

• Participate in the design and commissioning of complex testing systems, able to run and monitor tens of DCDC converters in real time, logging results in a database accessible from the web.
• Organise the different testing campaigns (electrical, radiation, and reliability).
• Actively participate in the large radiation, electrical, and reliability test campaign of the CERN DCDC converters, with final reporting and documentation.
