Machine Learning Engineer for Next Generation Triggers (NGT) (IT-CD-PI-2026-177-LD)

Introduction

You will develop and operate CERN's next-generation machine learning platform, enabling scientists and engineers to train, deploy and manage AI workloads at scale.

Working with cutting-edge technologies including Kubernetes, GPUs and cloud-native tools, you will help build the infrastructure supporting machine learning for the High-Luminosity LHC.

Functions

• Develop and operate the NGT machine learning platform, covering model training, hyper-parameter optimisation and serving, targeting optimal usage of detector resources.
• Manage cluster resources, integrate new resources, on-premises or via external resources (such as clouds or HPC centers), and optimise resource usage (e. g. via CPU/GPU/RAM affinity layouts) and the existing MLOps workflows to cover deployment, observability and lifecycle management & versioning of models.
• Extend the cloud native infrastructure to support advanced workload scheduling, system monitoring & accounting, as well as prompt cost control.
• Produce and present reference architectures, documentation and best practices to support CERN users and use cases.
• Ensure efficient collaboration with other groups in `IT and in other departments, as well as constant alignment with the evolving landscape of external research and industry organisations.
• Master's Degree or equivalent relevant experience in the field of Computing Engineering or a related field.

Experience

• Knowledge in machine learning systems, ideally with hands-on experience deployment and operating such services in production environments.
• Familiarity with one or more of the following areas.
• Kubernetes, containerisation, CI/CD, observability and model lifecycle management.
• Experience using GPU and/or other accelerator platforms, including performance tuning and optimisation of inference workloads.
• Familiarity with open-source ecosystems and willingness to contribute, evaluate upstream projects and follow community best practices.
• Enthusiasm for learning new technologies and contributing to cutting-edge scientific computing is essential.

Technical competencies

• Knowledge of operating systems.
• Knowledge of system configuration tools.
• Architecture and design of ICT systems.
• Identification and selection of relevant emerging ICT technologies.
• Knowledge and application of software life-cycle tools and procedures.

Behavioural competencies

• Working in Teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
• Solving Problems: addressing complex problems by breaking them down into manageable components.
• Managing Self: taking initiative beyond regular tasks and making things happen.
• Building Relationships: showing appreciation for the ideas and contributions of others and encourages others to express their views, even if controversial.

Language skills

• Spoken and written English, with a commitment to learn French.
