Job Description

Your responsibilities

Your future team:

* The Beams Department (BE), responsible for beam generation, diagnostics, and optimization for the LHC and its injector chain.

* The Industrial Control Systems Group (ICS), which provides technology frameworks for CERN-wide support of control systems across various domains.

Your future work:

CERN’s industrial control systems rely on Siemens’ Simatic WinCC Open Architecture (OA) SCADA system, along with the CERN-developed JCOP and UNICOS Frameworks. These technologies support over 850 critical control systems across CERN’s experiments, accelerator complex, and infrastructure, developed by a diverse global community of hundreds of users.

As a SCADA Engineer, you will help maintain, improve, and evolve the WinCC OA Service to meet CERN’s complex and changing needs.

Your key responsibilities will be:

• Evaluate the latest versions of WinCC OA to identify the new functionality that can be integrated into CERN’s frameworks, validate and prepare them for the use at the upcoming upgrade campaign at CERN;
• Support the operation of the CERN WinCC OA service by preparing and validating software distributions, containers and virtual machine images for CERN users;
• Participate in the development of the centralized monitoring/management system for WinCC OA license servers at CERN and support their operation;
• Contribute to the R&D activities performed in collaboration with Siemens/ETM, in domains such as the future web client for WinCC OA, containerization of SCADA systems, security, scalability or architectural enhancements;
• Contribute to the maintenance of the CI/CD infrastructure as well as to development of the frameworks using the CTRL++ scripting language and GUI-engineering tools of WinCC OA;
• Provide WinCC OA technology support the the users community, assisting in diagnosing of issues, following-up with ETM/Siemens Technical Support.

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.
