Power Electronics Engineer

Company Description
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.
Job Description
Introduction

Are you a passionate engineer who is at ease with powerful equipment? Are you ready to participate in the design, development, production, installation, and commissioning of some of the largest power converters in the world with very demanding performances? Take part in the challenge!

As a Power Electronics Engineer, you will join the Electrical Power Converter Group (TE-EPC) which is responsible for the power converters for the CERN accelerator complex, and the Medium Power Converter Section (TE-EPC-MPC) whose members develop and operate specific power systems. These systems are in the range of 10 kW up to several MW for magnets including those of the LHC injector chain and LHC superconducting magnets.

Functions

To extend its discovery potential, the LHC will need a major upgrade to increase luminosity (rate of collisions) by a factor of 10 beyond its design value. The HL-LHC is the project that will develop these new technologies and be in charge of the design, production, installation, commissioning and operation of the equipment required to reach this objective. In addition, maintaining and improving the availability of the LHC injector chain will be an asset for the HL-LHC project.

More details on the project can be found here: http://hilumilhc.web.cern.ch/

As a member of the HL-LHC project, you will interact with the different stakeholders in order to:

-Define power system specifications with particular focus on performance, integration and interfaces
-Participate in the commissioning of dedicated test facility, where test and validation of the powering solutions will be carried out
-Participate in the coordination of the converter standby service in charge of the operation of CERN test bench, dedicated to the test of accelerator sub-systems

As a Power Electronics Engineer you will be a member of the team responsible for the design, development, production, installation and commissioning of new power converters for the LHC, its injectors, as well as their operation and maintenance. Alongside, you will be also involved into the design of power converters for consolidation projects and your mandate will cover:

-Select the most suitable topology for each application (energy recovery, low noise, high availability) within the function of expected performances.
-Draw up technical specifications and ensure the follow-up of manufacturing and testing activities in the framework of industrial contracts.
-Ensure the effective reception, integration and commissioning of the new power converters in the LHC and the injectors.
-Participate in the operation and maintenance of power converters.

Qualifications
Master's degree or equivalent relevant experience in the field of electronics, electrical engineering, or a related field.

Experience:

-Demonstrated experience in power electronics in the power level of 10 kW up to several MW.
-Initial experience of management of projects, from the initial specifications to the final plan.
-Experience in operation, commissioning, or maintenance of power systems would be an advantage.

Technical competencies:
-Design and modelling of power electronic components and systems: power design, power electronics topologies, IGBT-Diode-Thyristor modules or Presspacks, system analysis, integration.
-Construction, test and installation of power electronic components and systems
-Design and implementation of analog control systems
-Design and implementation of digital control systems: MATLAB/SIMULINK or equivalent

-Use of PSIM or equivalent.

Behavioural competencies:
-Achieving Results: delivering high quality work on time and fulfilling expectations Having a structured and organized approach towards work; being able to set priorities and plan tasks with results in mind
-Working in Teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities Cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals.
-Communicating Effectively: ensuring that information, procedures and decisions are appropriately documented
-Managing Self: using time efficiently and effectively Working well autonomously; taking on activities and tasks without prompting
-Solving Problems: producing workable and timely solutions that meet requirements Finding the information needed to solve problems; making objective judgments based on all the facts available

Language skills:
.Spoken and written English. Ability to understand and speak French in professional contexts or an undertaking to acquire it rapidly.
