Materials Engineer - Polymers and Composites (TE-MSC-SMT-2026-172-LD)

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.

Introduction

You will join CERN's Polymer Laboratory within the Superconducting Magnet Technology section to develop and qualify advanced polymer and composite materials.

You will contribute to the design, validation and implementation of innovative materials, used in CERN accelerator systems within a cryogenic, high-voltage and radiation environment.

Functions

- Develop and qualify novel polymer and composite materials for superconducting magnets and accelerator technologies, with particular emphasis on cryogenic operation, high-voltage insulation and radiation resistance.
- Design and validate manufacturing and processing techniques for superconducting magnet insulation systems, including resin transfer processes, bonding technologies, composite fabrication and additive manufacturing.
- Lead research and design projects within the Polymer Laboratory to address the evolving needs of CERN accelerator complex and experimental facilities.
- Contribute to the laboratory developments by identifying material technologies and processing techniques and establishing new experimental capabilities.

Behavioural competencies

- Working in Teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
- Demonstrating Accountability: taking responsibility for own actions and decisions.
- Solving Problems: identifying, defining and assessing problems, taking action to address them.
- Communicating Effectively: listening actively to others and letting others speak.

Language skills

- Spoken and written English, with a commitment to learn French.

Requirements

Master's Degree or PhD or equivalent relevant experience in the field of material engineering, mechanical engineering, chemical engineering or a related field.; Experience in polymer and composite materials engineering, including development of manufacturing processes for fibre-reinforced composites.; Experience in material characterisation techniques, such as mechanical, thermal or chemical analyses.; Experience coordinating or leading multidisciplinary technical and research and design activities involving multiple stakeholders.; Knowledge of superconducting magnet construction and technologies, or of materials for cryogenic, high-voltage or radiation environments, would be an asset.; Knowledge of radiation effects and ageing of materials.; Knowledge and application of mechanical testing (destructive).; Knowledge and analysis of materials failure.; Knowledge, application and processing techniques of polymers and composites.

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.
