Company DescriptionAt , 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 DescriptionIntroductionYou will design, integrate, and operate advanced machine learning capabilities within CERN's machine learning platform, enabling scalable, secure, and reusable ML services for scientific and IT workloads. Working closely with experiments and service teams to onboard their ML use cases in a reliable, performant and sustainable manner, you will build CERN's next-generation LLM and AI agent platform, tuning models into secure, scalable services for scientific and operational use cases. You will be responsible for the design and integration of the selected tools after extensive due diligence and validation against CERN use cases in all departments.Functions
  • Develop and operate the machine learning service of CERN IT, covering model training, hyper-parameter optimisation and serving, targeting optimal usage of accelerator resources.
  • Integrate and operate LLM and AI agent capabilities within the CERN machine learning service, including scalable model serving, agent frameworks, and secure multi-tenant access.
  • Extend existing MLOps workflows to cover deployment, observability and lifecycle management of models, agents and RAG pipelines targeting CERN and external data sources.
  • 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.
QualificationsMaster's degree or equivalent relevant experience in the field of Computing Engineering or a related field.Experience:
  • Strong background in machine learning systems with hands-on experience deployment and operating such services in production environments.
  • Solid MLOps and cloud native skills, including Kubernetes and containerisation, CI/CD, observability and model lifecycle management.
  • Proficiency with 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.
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.
