Detector Systems Electronics Engineer

What you'll do

The Electronic Systems for Experiments (ESE) Group in CERN’s Experimental Physics Department develops and supports electronics for particle physics experiments, from R&D through production, testing, and maintenance. Within ESE, the Front-End (FE) section designs and integrates on-detector systems for signal processing, data transmission, and power distribution, addressing challenging requirements such as radiation tolerance, low-mass materials, and high component density. As an Electronics Engineer in this section, you will take responsibility for the design, testing, and integration of these systems into CERN experiments, working within multi-disciplinary and international teams to ensure performance, quality, and reliability.

Your responsibilities

Design, build and integrate complex detector systems and the required electronics, collaborating closely with physicists, engineers and specialised technicians.
Design and develop complex multi-chip electronic modules and electronic boards integrating mixed-signal ASICs and FPGAs for particle detectors.
Prototype, develop, test, and debug highly specialised on-detector electronics.
Develop and commission systems for laboratory-based and mass-production testing of electronic systems.
Manage procurement and large-volume manufacturing of electronic components and systems through industrial contractors.
Support production and quality assurance programs with collaborating institutes and industrial partners.
Design and maintain infrastructure for the integration and commissioning of modules into CERN experiments.
Guide and mentor students, technicians, and early-career scientists and engineers.
Present project progress and outcomes at collaboration meetings and international conferences.
Document designs, processes, and systems.
