Job Details

The European Synchrotron, the ESRF, is an international research centre based in Grenoble, France.

Through its innovative engineering, pioneering scientific vision and a strong commitment from its 700 staff members, the ESRF is recognised as one of the top research facilities worldwide. Its particle accelerator produces intense X-ray beams that are used by thousands of scientists each year for experiments in diverse fields such as biology, medicine, environmental sciences, cultural heritage, materials science, and physics.

Supported by 21 countries, the ESRF is an equal opportunity employer and encourages diversity.

As a power electronics control engineer, you will join the Power Supplies Group which is responsible for the design, maintenance and operation of the complex electrical systems used to power the accelerator electromagnets.

Your tasks will be:

  • Design and improvement of the embedded system used to control the power converter of the group:Modelling and simulation of power converters with PLECS / MATLAB Simulink and design of their control laws (current / voltage regulation, etc.);
  • Implementation of real-time control algorithms on DSP / FPGA targets: design of the control system architecture, writing of the software specification, coding and debugging of the program;
  • Validation tests and tuning of the regulators on the power converter on a test bench and then in its final environment;
  • Maintenance and operation of the group’s equipmentContinuous improvement of equipment reliability: analysis of root cause of failures, proposal of design modifications (hardware/software);
  • Preventive maintenance activities during accelerator shutdown periods: inspection, modification and functional testing of equipment;
  • Standby and on-call duties:  on-site intervention day and night to troubleshoot equipment failures, remote technical support to the Accelerator Operation Group. Total of seven one-week standby duties per year;
  • Minimum 3-5 years working experience in a similar role;
  • Proficiency in control engineering (transfer function, feedback and feedforward loop, PID controller);
  • Good knowledge of various topologies such as SCR rectifier, H-bridge, Inverters, and their control (PWM, etc.);
  • Experience in modelling and simulation of electrical circuits with tools such as PLECS, PSIM, SIMSCAPE;
  • Experience with (or willingness to learn) TI Code Composer Studio IDE or a DSP code generation tool such as PLECS Coder or MATLAB Embedded Coder;
  • Experience in design of FPGA based control system would be a plus;
  • Familiar with software version control systems such as GIT or SVN;
  • Practical experience in testing and troubleshooting electrical/electronic equipment;
  • Proactivity and ability to work with minimal supervision;
  • Analytical mind and strong problem solving skills;
  • Ability to multi-task and prioritize commitments effectively;
  • Good writing skills;
  • Ability to work as part of a team;

ESRF imageThe ESRF is a landmark for fundamental and innovation-driven research, providing scientists from all over the world with the most brilliant X-rays to unveil the structure of materials and the mechanisms of life, down to atomic resolution. Our teams contribute to addressing the complex global challenges that our society faces.

Why work for us
For more than 30 years, the ESRF has enabled major scientific breakthroughs in the understanding of living and condensed matter. With its new Extremely Brilliant Source (EBS), the ESRF is opening new vistas for X-ray science, providing a growing community of scientists with unique facilities to tackle the complex global challenges facing our society. Scientific and technical interdisciplinarity are at the core of the ESRF’s success.

Training and development
The ESRF provides a unique and vibrant setting for early-career scientists, engineers and technical staff to train and develop their scientifc and technical abilities, thus driving the transfer of expertise to other research projects, to industry and to society at large. At the ESRF, we dedicate a significant part of our yearly budget to training our staff. Our human resources policy encourages internal mobility and many of our staff members have the opportunity to change jobs during their career.

Graduate schemes
The ESRF supports many initiatives and public events aimed at sharing knowledge of science and engaging with a diverse range of audiences, including school students and young children. At the heart of this mission, the ESRF offers different educational programmes for students of all levels.

Each year, the HERCULES European school, the Joint Universities Accelerator School, and the joint International Summer Student programme that we run with the Institut Laue-Langevin, offer introductory lectures and specialized courses, practical sessions, tutorials and visits to other European research facilities.

What we are looking for
We are looking for passionate and curious people who are eager to collaborate in an eminently international open environment.

We welcome people who wish to contribute to a better understanding of the world around us and to inspire and drive progress.

We welcome people in many different disciplines (e.g. science, engineering, management) who contributes, through their diversity (gender, nationality, language, culture) and their professional skills to push the frontiers of science.
