Electronics Technician (EP-CMS-ID-2026-147-LD)

Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.

Job Description

Introduction:

You will support the integration and commissioning of services and infrastructure for the CMS Tracker construction at CERN, with a focus on the preparation and validation of services, as well as the reception testing of components and detector assemblies. The role also includes the setup and operation of test electronics for the commissioning of detector services and the functional testing of detector components and assemblies.

Functions:

• Prepare and support the installation and commissioning of services and infrastructure for large detector assemblies (e.g. cables, racks and test setups).
• Set up and operate test electronics and commissioning setups (e.g. interlocks, sensor interfaces and thermal test configurations).
• Perform reception testing of detector substructures and components, including power distribution hardware delivered to CERN.
• Validate integrated electrical services (power, signal and grounding interfaces) installed on detector assemblies and troubleshoot issues during construction.
• Maintain traceability by updating the production database with acceptance test reports and installation data.

Qualifications

• Higher technical diploma or equivalent relevant experience in the field of Electronics or a related field.
• Additional relevant certificates are considered an asset.

Experience:

• Proficiency in the assembly, installation and wiring of electronic components (e.g. cabling, soldering, SMD components, sensors, boards).
• Hands-on experience with electrical testing and measurement techniques using laboratory and test equipment (e.g. multimeters, power supplies, oscilloscopes), including the preparation of test setups.
• Experience in maintaining laboratory equipment and inventory, updating technical databases, and documenting testing procedures and results.

Technical competencies:

• Assembly of electronic components.
• Knowledge and application of instrumentation and measurement techniques.
• Operation and maintenance of electrical/electronic systems.
• Technical documentation of electric/electronics systems.

Behavioural competencies:

• Working in Teams: building and maintaining constructive and effective work relationships.
• Communicating Effectively: listening actively to others and letting others speak.
• Demonstrating Flexibility: adapting quickly and resourcefully to shifting priorities and requirements.
• Solving Problems: identifying, defining and assessing problems, taking action to address them.

Language skills:

• Spoken and written English or French, with a commitment to learn the other language.
