RF Power Amplifier Design Engineer; SY-RF-LIS--LD

• Contract

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.

Introduction

You will engage in the development of RF amplifier systems, which power RF resonators for particle beam acceleration. Theobjectiveis to replace ageing tube electronics with solid-state technology in line with beam requirements.

Functions

• Lead the design of Solid-State Power Amplifiers, including calculations, simulations, component selection, layout definition and PCB design, as well as RF system and component modelling and characterisation through planned measurements.
• Define manufacturing methods, specifications and acceptance criteria, and provide progress reporting and documentation.
• Collaborate with engineering teams for prototyping, testing and diagnostics, and oversee the operation, maintenance, repair and upgrade of existing RF equipment.
• Support beam-based measurements, analyse equipment performance and ensure compliance with all safety procedures.
• Prepare technical reports, presentations and other documentation, contributing to effective knowledge sharing.

Master's degree or PhD or equivalent relevant experience in the field of Electronics engineering, RF and microwave electronics, or a related field.

Experience:

• Proficiency in radio-frequency circuit design and testing with specific emphasis on Solid-State Power Amplifiers. Experience with microwave and RF simulation and analysis techniques.
• Familiarity in circuit design foranalogue electronics used in power RF systems.
• Demonstrated experience with microwave and RF amplifier measurements, includingcomponentcharacterisation and model extraction.
• Initial experience in managing electronic projects from conceptual design to testing,prototyping and manufacturing phases, in-house and in industry.
• Experience in preparing technical reports and engineering specifications.
• Design, construction and testing of RF power generation components and systems;
• Design of high-frequency electronics and microwave circuits;
• Testing and measurement of analogue electronic circuits;
• Knowledge and application of RF techniques;
• Knowledge and application of quality and reliability assurance techniques in electronics.
• Achieving Results: delivering high quality work on time and fulfilling expectations.
• Working in Teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
• Communicating Effectively: expressing opinions, ideas and suggestions with conviction and in a logical/structured manner; keeping to the point.
• Solving Problems: identifying, defining and assessing problems, taking action to address them.
• Learning and Sharing Knowledge: sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer.

Spoken and written English, with a commitment to learn French.
