Company Description

At CERN, the European Organisation 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.

Job Description

Introduction

Great technology requires great people! Are you an experienced developer eager to contribute to an engineering platform that supports some of the world’s most complex equipment and is used by thousands of engineers and technicians? Do you want to build your career in an international, dynamic environment at the forefront of modern science? If so, join our ambitious and dynamic team of engineers and IT specialists. Take part!

The Information Management Group within the Engineering Department delivers and supports software solutions for CERN’s engineering community. One of its core missions is the development and maintenance of CERN’s Product Lifecycle Management (PLM) systems, which handle design data and technical documentation for both the accelerator complex and its supporting infrastructure. The group is currently in a challenging project of modernising the existing landscape of heterogeneous engineering applications by bringing it to the next level, allowing the Organisation to move forward towards integrated digital processes and engineering Digital Twins. As of today, over 5000 users depend on the software provided by the group.

Functions

As a software engineer, you will be responsible for supporting, maintaining, and further enhancing our multi-CAD and PLM capabilities. You will in particular, implement CAD and PLM specific modules matching users’ needs, including both web and desktop applications. You will also explore the potential of Artificial Intelligence to accelerate innovation within our engineering platform. Finally, you will contribute to solutions for Digital Twins and Virtual/Augmented Reality.

You will:

• Play a key role in the software design, system architecture, and integration with enterprise applications.
• Work with users to transform needs into application requirements and design specifications.
• Implement custom web and desktop applications as part of CERN’s PLM platform and its related applications.
• Introduce Machine Learning capabilities into the PLM system or other applications developed within the group.
• Integrate CAD tools with 3D visualisation technologies: web and native viewers, virtual/augmented reality.
• Take responsibility for code reviews, testing, monitoring, and general system management tasks, including configuration, deploying upgrades and patches.
• On-board, coach, and mentor junior colleagues in the team.
• Play an active role in the common and continuous effort of improving both the services and tools provided, including user support and documentation.
