Electrical Engineer fSystem Optimisation (SY-EPC-FPC-2025-75-GRAE)

Job Description

Join the forefront of particle accelerator innovation!

By developing and applying an advanced optimization environment, you will take part in designing the next generation energy systems for the Future Circular Collider (FCC-ee and FCC-hh) at CERN.

As an Electrical Engineer, you will join the Fast Pulsed Converters (FPC) Section of the Electrical Power Converters (EPC) Group within the Accelerator Systems (SY) Department. However, in this position, you will also have the opportunity to work together with professionals from other departments and sections as well.

As of our team, you will contribute to building an optimization tool that integrates multi-domain models, including power converters, civil engineering, cooling & ventilation, magnets, and Radio Frequency (RF) systems. The ultimate goal is to explore and define the most efficient and sustainable powering configurations for thousands of magnets and RF systems within one of the world's most ambitious scientific infrastructures.

Your work will directly contribute to minimizing both capital investment (CAPEX) and operational costs (OPEX), while supporting CERN's sustainability goals for future energy management. This role offers a unique opportunity to work at the interface of cutting-edge engineering, system modelling, and environmental responsibility — shaping the energy systems of tomorrow's largest particle accelerator.

Your main tasks:

• Contribute to development of the optimisation tool
  • Define the optimisation framework
  • Integrate existing accelerator equipment models in Python
• Define optimisation scenarios for powering the FCC
• Present your findings at workshops and conferences

Your profile

Skills

• Experience with Python;
• Experience in analytical modelling of physical systems (electricity, mechanical or other domains);
• Knowledge of numerical optimization;
• Knowledge of documentation principles
• Spoken and written English, with a commitment to learn French.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• By the application deadline, you have a maximum of two years of professional experience since graduation in Electrical Engineering or Physics (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
• You have never had a CERN fellow or graduate contract before.
• Applicants without University degree are not eligible.
• Applicants with a PhD are not eligible.

Job closing date: 25th of May at 23:59 (midnight) CET.

Contract duration: 24 months, with a possible extension up to 36 months maximum.

Working hours: 40 hours per week

Target start date: 01-July-2025

Job reference: SY-EPC-FPC-2025-75-GRAE

Field of work: Electrical or Electronics Engineering

What we offer

• A monthly stipend ranging between 5196 and 5716 Swiss Francs(net of tax).
• Coverage by CERN's comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
• Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract.
• 30 days of paid leave per year.
• On-the-job and formal training at CERN as well as in-house language courses for English and/or French.

About us

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.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
