Power Electronics Engineer for high-power systems (SY-EPC-HPC-2025-109-LD)

Power Electronics Engineer for high-power systems (SY-EPC-HPC-2025-109-LD)

• Contract

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.

Introduction

We are seeking a Power Electronics Engineer to join our team and contribute to the development of large-scale power electronics systems that drive CERN’s particle accelerators. These accelerators act as a powerful microscope, enabling scientists to explore the fundamental laws of nature. In close collaboration with experts in power electronics, digital control, and system integration, you will work on the design, simulation, installation, testing, and commissioning of high-power systems, including Static Var Compensators (SVCs) and power converters in the multi-megawatt range, as well as their operation and maintenance.

You will join the Accelerator Systems Department (SY), responsible for the beam-related technical systems of CERN’s accelerators. The SY teams design, build, and operate equipment systems across the entire CERN accelerator complex while also leading ambitious R&D programs for future advancements. Within this department, the Electrical Power Converter Group (EPC) oversees the electrical power systems that supply the CERN accelerator infrastructure. You will be part of the High-Power Converter Section, working in a dynamic and collaborative environment where knowledge sharing and innovation are key.

Functions

As a Power Electronics Engineer, your work will involve:

1. Contributing to the construction, testing, and deployment of Static Var Compensators (SVC) and high-power converters;
2. Design and modeling of power electronic components and systems: Performing simulations of SVCs and specifying key system components;
3. Application of advanced power electronics techniques: Developing and simulating control systems for SVCs;
4. Design and implementation of digital control systems: Implementing control strategies within CERN’s control platform;
5. Operation and maintenance of power electronic components and systems: Analyzing operational challenges, proposing and implementing solutions, and coordinating system interventions and preparing test procedures and reports;
6. Supervision of junior team members and personnel from external companies.

Qualifications

Master's degree or PhD or equivalent relevant experience in electrical or electronics engineering or a related field.

Experience:

1. Design of power converters and power systems, with the ability to use simulation tools such as MATLAB/Simulink or equivalent;
2. Understanding of analog and digital control principles, with the ability to program microcontrollers and develop logic for programmable systems;
3. Prior experience in the design, operation, and/or maintenance of power systems in the multi-megawatt range is advantageous;
4. Knowledge and application of power electronics techniques, especially common topologies for high-power converters and reactive power compensation systems;
5. Design and modeling of power electronic components and systems;
6. Operation and maintenance of power electronic components and systems;
7. Knowledge and application of automation and control theory;
8. Managing self: working autonomously;
9. Achieving results: structured and organized work, setting priorities;
10. Solving problems: breaking down complex issues;
11. Working in teams: collaborative and active participation;
12. Communicating effectively: documenting procedures and decisions.

Proficiency in spoken and written English or French, with a commitment to learn the other language.

Eligibility and closing date:

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. We welcome applications from all Member States and Associate Member States.

This vacancy will be filled as soon as possible. Applications should reach us no later than June 24, 2025, at 23:59 CET.
