Job description

Initially as RF engineer your main responsibilities will be to carry out testing of the RF systems already installed, support with installation and later the role will include system operation both with and without beam. Once you have gained experience with the RF systems at ESS, the role may evolve into supervision or support of additional test teams.

You will be working closely with the different technical disciplines within the RF group such as High power amplifiers, interlock systems, LLRF and a multitude of other subsystems as well as the other teams both within the Accelerator Division and other divisions.

Your main areas of responsibilities as an RF Engineer will be to:


• Coordinate, carry out and document system setup and RF system testing;
• Conditioning and test of high power amplifiers and high power components;
• Support and supervision of additional test teams;
• Suppport operations with system handover and supervision;
• Manage installation of future systems and RF projects to improve performance and reliability;
• Carry out fault analysis both during the test phases and later in operations with the view of improving performance and reliability;
• Assist with planning and budgeting for assigned projects;
• Oversee and plan for operational and shut down activities;
• Work with, and direct, In-Kind partners and industrial partners.

Qualifications

The successful candidate will have a broad background in several disciplines relevant for RF systems as well as experience of installation, commissioning and operation of complex, preferably high power RF systems for accelerators. The subsystems include high power sources, solid state amplifiers, RF distribution, phase reference lines, LLRF, power supplies and auxiliary systems, interlock systems and controls.

You will have a strong academic background such as a Physics, Electrical Engineering or RF Engineering degree or a higher qualification. In addition, you can demonstrate an aptitude towards learning and have the desire to develop yourself and others within this field.

We truly believe that you have:
