About this position

The summary below is published by European Organization for Nuclear Research on the official vacancy notice. Our own analysis — salary realism, comparable openings, career trajectory, language profile — follows further down the page.

At [CERN](http://home.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.

**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.

* 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.

**Eligibility and closing date:**

Career trajectory

Career progression for this grade staff is governed by Articles 44 to 46 of the Staff Regulations (consolidated text on EUR-Lex) and Annex IB on the promotion procedure. Step increases are automatic every two years (Art. 44); grade promotion is competitive, based on the appraisal exercise (Art. 45) and the Career Development Review. For roles at CERN, progression to the next grade typically takes three to five years on merit, with two-yearly step increases in between. Article 46 governs the classification at recruitment, which sets the starting step within the grade (usually step 1 for external recruits without prior EU service, step 2 or 3 where relevant professional experience is recognised).
Mobility within the institutions is encouraged via the inter-institutional and intra-institutional vacancy publication system: temporary agents who pass the probation period and reservists from EPSO laureate lists can typically apply to internal vacancies after one year of service. Lateral moves between Directorates-General reset the seniority clock for promotion only if the new post carries a different grade.

Language profile

Beyond the formal language requirements stated in the vacancy notice, the day-to-day working languages at this employer are English and French in roughly equal measure, with German appearing in some technical files. Internal meetings and most policy drafting in Brussels run in English; French remains the preferred internal language in Luxembourg-based services and parts of DG TRADE.

Application cadence

CERN has not advertised another comparable role with the same grade and Engineering signature in the past twenty-four months. This opening has rarely been seen on the EU Careers feed and may be the first such posting in our two-year window. Applicants who pass the eligibility checks should not assume the same profile will reopen on a predictable cadence.
