Test Engineer for Power Electronics (EP-ESE-ME-2026-49-GRAE)
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.
