Vacuum Systems Technical Engineer

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. Find out more on http://home.cern.

Job Description
Introduction

Are you ready to work on one of the most advanced vacuum systems on the planet?

With 130 km of cutting-edge vacuum vessels, CERN operates one of the largest and most complex vacuum systems ever built. If you're driven by the challenge of pushing the boundaries of science and technology, this is your chance to make a mark. Join the Vacuum, Surfaces, and Coatings Group and be part of something extraordinary!

The Vacuum, Surfaces, and Coatings (VSC) Group is at the forefront of CERN’s pioneering technological research, overseeing all high and ultra-high vacuum systems across the CERN accelerators. From design to operation, surface engineering to acceptance tests, we handle it all. The Beam Vacuum Operation section (BVO) ensures the flawless operation and continuous upgrade of the vacuum equipment critical to the Large Hadron Collider (LHC), the most powerful particle accelerator ever built. This includes the systems that enable hadron beams to circulate through superconducting magnets and detectors.

Functions

Within the VSC Group of the Technology Department, you will:

Operate, maintain and consolidate complex and highly specialised ultra-high vacuum equipment, instruments and prototypes for particle accelerators;
Carrying out the technical design phase including writing technical specifications, preparing drawings, and supervising and reviewing the detailed design studies;
Participate in projects aimed to upgrade and consolidate existing vacuum systems as well as in other projects involving collaboration with various teams in charge of other accelerator systems and engineering fields;
Organize production of prototypes and carry out laboratory functional tests to assess the compliance of prototypes with both vacuum and structural acceptance criteria;
Perform follow-up of the production life cycle for the new equipment involving regular front-line communication with both internal and external collaborators and companies;
Coordinate the on-site acceptance tests of the LHC experimental vacuum chambers;
Organize, participate and lead interventions in the accelerator complex and LHC experiments for regular maintenance as well as major upgrade and consolidation activities;
Perform regular follow-up of LHC beam vacuum operation, including reporting and analysis of non-standard behaviours, and implement required preventive or corrective actions.
