Introduction

Are you a talented software engineer, passionate about Full-Stack Web development projects? Do you have in-depth experience with Web, python and database frameworks? Are you comfortable in a collaborative development environment using git, Linux and continuous integration techniques? Then join the Electrical Power Converter group for a unique challenge as the next step in your career. CERN, take part!

You will join the TE Department, the Electrical Power Converter Group (TE-EPC), responsible for the power converters for the whole CERN accelerator complex, and the Converter Controls Software Section, which develops and supports the power converters control software.

The section is responsible for a large distributed control system for more than five thousand power converters and a dozen static VAR compensators. These range in power from a few Watts to 150MW and are used to drive current through the magnets in the accelerators, transfer lines and experiments. The magnets guide and focus the particle beams, so precise control of the currents is critical.

Functions

As a software engineer in the CCS Section, you will be responsible for the converter controls expert applications (Web UI, python back-end, Oracle or Postgres DB). These are used by the power converter experts at CERN and other labs that use CERN converter controls.

• Support and extend the existing expert applications developed by the section.
• Supervise junior software engineers working on the same project.
• Identify requirements for new expert applications in collaboration with the power converter experts and prepare written specifications.
• Design, develop, test, deploy, maintain and support the new expert applications.
• Analyse existing, complex labour-intensive workflows and create automated solutions with well-designed, intuitive user interfaces.
