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 The ALICE Technical Coordination team is expanding to address the increased mechanical‑engineering workload associated with the scheduled Large Hadron Collider (LHC) Long Shutdown periods in 2026‑2028 (LS3) and 2033‑2034 (LS4), including detector decommissioning and installation activities, the development of the entirely new ALICE 3 detector, and the preparation of future detector infrastructure.
As a Mechanical Engineer, you will contribute to the execution of LS3 installation activities and the design and construction of the ALICE 3 detector system, working within a multidisciplinary team of engineers, technicians, and designers.
Functions
Participate in the ALICE detector upgrade programme for LS3, specifically the installation of the new beam pipe, silicon tracker and forward calorimeter.
Provide mechanical engineering support and on‑site supervision at the experiment site during the programmed maintenance periods.
Provide engineering support for the ALICE3 upgrade programme for LS4: definition of the experiment layout including integration of detectors, services, and all the related infrastructure.
Design detector standard metallic and carbon‑composite structures, supported by structural analyses to assess performance under mechanical, thermal, and dynamic loads using appropriate material models and failure criteria, ensuring strength, stability, and compliance with safety requirements.
Work closely with stakeholders, including detector experts, collaboration members, external companies and technical support teams from CERN and ALICE collaborating institutes.
Support the ALICE Technical Coordination team in supervising designers and technicians during the daily work.
Qualifications
Master’s Degree or equivalent relevant experience in the field of Mechanical Engineering or a related field.
Experience
Experience in the design, construction, and assembly of mechanical systems.
Proven experience in the use of CATIA for CAD design.
Knowledge of ANSYS for structural analysis.
Experience working in a multidisciplinary team, including supervision of technical engineers and technicians.
Proven ability to coordinate work done by external companies and contractors.
Technical competencies
Design and analysis of mechanical structures.
Knowledge and application of numerical modelling in solid mechanics.
Knowledge and application of non‑metallic composites.
Production of 2D drawings and 3D models.
Organisation, planning and control: coordination of activities involving different technical fields (mechanical work, metallic structures, heavy handling etc.).
Behavioural competencies
Achieving Results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
Managing Self: working well autonomously; taking on activities and tasks without prompting
Demonstrating Flexibility: readily accepting new tasks or work/projects.
Working in Teams: building and maintaining constructive and effective work relationships.
Demonstrating Accountability: taking responsibility for own actions and decisions.
Language skills
Spoken and written English, with a commitment to learn French.
Eligibility and closing date Applications should normally reach us no later than
10.07.2026 at 23:59 CEST .
Employment Conditions
Contract type: Limited duration contract (5 years). Subject to certain conditions, holders of limited‑duration contracts may apply for an indefinite position.
Working Hours: 40 hours per week
Job Flexibility: Fully Onsite
This position involves:
Work in Radiation Areas.
Interventions in underground installations.
Work during nights, Sundays and official holidays, when required by the needs of the Organization.
Job grade: 6-7
Job reference: EP-ALI-TC-2026-127-LD
Field of work: Mechanical Engineering
Benchmark Job Title: Mechanical Engineer
Global Benefits
A competitive salary (tax free), increasing in line with your years of relevant experience.
30 days of paid leave per year plus 2 weeks annual closure.
Coverage by CERN’s comprehensive health insurance scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
Family, child and infant monthly allowances depending on your individual circumstances.
A relocation package (installation grant, removal, travel expenses) depending on your individual circumstances.
Possibility to extend your contract up to 8 years + eligibility for indefinite contract tenure.
