Mechanical Engineer for the CMS High-Granularity Calorimeter
Datum: 5 oktober, 2026 Tid: 11:59
Placering: CERN
What you'll do
As a Mechanical Engineer, you will contribute to the development, procurement, assembly, testing and installation of innovative mechanical structures for the High Granularity Calorimeter (HGCAL) of theCompact Muon Solenoid experiment , working with advanced materials and challenging structural and thermal requirements.
You will help oversee the surface assembly and testing of the 250-tonne detector, including its CO? cooling, dry gas, cabling and fibre services, as well as its installation and commissioning 100 metres underground. Working in a multinational, multidisciplinary team, you will apply your expertise in structural and thermal calculations, finite element analysis and 3D CAD.
Your responsibilities
- Coordinate a team of technicians in assembling and testing the steel structures of HGCAL, comprising more than 200 tonnes of steel plates per endcap.
- Provide engineering support for all activities at CERN related to the large-scale active detector components, known as “cassettes” (30-60-degree segments of circular structures with diameters of up to 5 m). This will include the cold testing of “electromagnetic cassettes” and their subsequent stacking with lead plates to form the complete electromagnetic endcaps.
- Integrate the hadronic cassettes into the steel structures and provide support for their testing.
- Integrate the electromagnetic (30 tonnes) and hadronic (200 tonnes) sections, including their cabling and piping, and support subsequent large-scale testing on the surface.
- Help oversee the lowering of the HGCAL endcaps into the CMS cavern and their connection to CMS, including the connection and testing of services
