What you'll do

Your job will be to take a central role in maintaining and evolving the CERN Industrial Controls Frameworks used by a community of more than 500 users world-wide. The work will focus on the supervisory/monitoring layer of the Frameworks, which builds on top of the WinCC OA SCADA system.

You will be designing, developing and supporting the required tools, technologies, and services to implement large distributed control systems for CERN’s accelerators, particle detectors and technical infrastructure.

Your responsibilities

Develop software components spanning across all layers of modern control systems for integration in the CERN Industrial Controls Frameworks including gathering of requirements, design, prototyping, implementation, testing and maintenance.
Provide CERN-wide support for the Industrial Controls Frameworks and their underlying stack of technologies, notably for the SCADA layer, including in situ expert assistance and training, dialogue with the control system developers using the Framework.
Proactively contribute to the standardisation and optimisation of industrial control systems; apply quality assurance tools and methods; monitor and analyse the performance of the running systems; propose improvements in the technology landscape and recommend solutions.
Participate in and lead cross-team technical initiatives, deliver proof of concepts demonstrating product feasibility to the clients.
Consolidate, modernise and review the Frameworks to meet evolving needs and assure long-term maintenance and compatibility.
Maintain and improve group-wide high standards and guidelines of software engineering practices.
