Functions

As a Cryogenics Instrumentation Technician you will: 

• Support the installation operation and maintenance related to cryogenic instrumentation systems and associated radiation-tolerant conditioning electronics (e.g. temperature transmitters (TT) pressure transmitters (PT) level transmitters (LT) flow transmitters (FT) and electrical heaters (EH)). 
• Contribute to calibration and testing activities for cryogenic instrumentation systems (TT PT LT FT). 
• Assist with design specification procurement installation and commissioning of the cryogenic instrumentation for the High Luminosity cryogenic system upgrade. 
• Diagnose and resolve technical issues in cryogenic instrumentation systems supporting particle accelerators and associated experiments contributing to optimal and reliable system performance. 
• Collaborate with multidisciplinary teams (e.g. controls electrical and electronics) to ensure the reliability availability and continuous improvement of cryogenic systems. 
• Monitor and report on contractors compliance with safety and quality standards during maintenance and installation interventions. 

Qualifications :

Higher technical diploma or equivalent relevant experience in the field of Metrology or a related field.

Experience:

You have demonstrated experience in:  

• Conducting technical activities related to instrumentation systems or associated radiation-tolerant conditioning electronics (e.g. TT PT LT FT EH);
