Mechanical Designer (EN-MME-EDS-2025-241-LD)

At CERN, the European Organisation 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 Join a multidisciplinary project team designing, fabricating and testing a new generation of components for the High-Luminosity Large Hadron Collider (HL-LHC). Be in charge of the design of the new HL-LHC cryogenic distribution lines (QXL), relying on computer-aided design (CAD). Structural and thermomechanical studies, design of pressure equipment, cryogenics, ultra-high vacuum technology, sustainable design and manufacturing, safety, reliability, product lifecycle management are just a few of the keywords related to this position.

Functions Technical management of design office jobs closely collaborating with a team of mechanical engineers, designers and draftsmen, in particular for the Cryogenic Distribution Lines for the HL-LHC project. Analysis of design requirements based on functional specifications or other relevant information. Execution of design studies of mechanical assemblies, components, tooling, equipment integration and layout. Creation of detailed 3D models and technical drawings (including specification, detail, manufacturing, assembly, installation, as-built and verification drawings), in consultation with CERN manufacturing and materials experts and in compliance with relevant design and drafting standards. Preparation of the project documentation according to the Design Office quality assurance procedures. Follow-up, in close interaction with other teams and services, of the manufacturing, assembling and installation of mechanical components. Preparation of presentations, technical reports, engineering specifications and calculation notes.

Experience: Proven experience as a designer in a mechanical design office, performing mechanical dimensioning and using standard mechanical analysis tools (both analytical and numerical). Proven experience with computer-aided design. Experience in the production of technical drawings of mechanical components and systems, ideally according to ISO Geometrical Product Specifications (GPS) standards for drawing dimensioning and tolerancing. Experience with the CATIA computer-aided-design software suite would be an asset. Technical competencies: Design and construction of machines: with ability to analyse and solve mechanical engineering problems using strength of materials and materials selection principles. Design and analysis of mechanical structures: with basic knowledge of numerical and analytical calculation methods. Production of 2D drawings and 3D models: in compliance with relevant standards for drawing dimensioning and tolerancing, in particular ISO Geometrical Product Specifications (GPS). Assembly of mechanical structures and equipment: knowledge of manufacturing methods and processes such as machining, forming, joining (e.g. welding, brazing). Configuration and use of information management systems: with the ability to effectively use Computer Aided Design (CAD) and Product Lifecycle Management (PLM) tools. Behavioural competencies: Managing Self: working well autonomously; taking on activities and tasks without prompting. Building Relationships: showing courtesy and consideration in dealings with others. Working in Teams: cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals. Solving Problems: identifying, defining and assessing problems, taking action to address them. Demonstrating Flexibility: adapting quickly and resourcefully to shifting priorities and requirements. Language skills: Spoken and written English, with a commitment to learn French.
