Jobs at CERN

Design, develop, and deploy LLM-based and agentic AI solutions for accelerator control and operational workflows. Build RAG pipelines with vector databases and embeddings, contribute to ATS AI Core Team, define MLOps/CI-CD patterns, safety and evaluation frameworks, and collaborate across CERN engineering and IT teams.

Plan, schedule and coordinate installation and maintenance activities for CERN accelerators. Produce baseline schedules, resolve co-activity conflicts, liaise with stakeholders, manage schedule impacts and safety compliance, track progress and report deviations, and maintain 3D-CAD/integration and planning tool workflows.

Develop, maintain and support full‑stack web applications and databases for power converter experts. Gather user requirements, iterate features, lead sprints, provide debugging and application support, and collaborate using Scrum. Participate in on‑call/stand‑by duties.

Provide financial and administrative support to the CMS Collaboration: manage allowances, invoices, orders and payments; prepare financial reports and web content; administer contracts and personnel formalities; coordinate budgets, agreements and meetings; ensure compliance with CERN procedures and act as back-up to the supervisor.

Develop and maintain Garfield++ simulation tools for gaseous detectors, optimise and characterise gas mixtures, coordinate collaboration within DRD1, support experimental validation and data analysis, supervise team activities, and upgrade simulations to meet evolving detector R&D needs.

Design, develop and commission distributed control systems for large power installations using Siemens S7-1500 PLCs and CERN's UNICOS framework. Create Matlab/Simulink HIL models, write Python test scripts, contribute to CI/CD and automated testing, and supervise students during development and commissioning activities.

Design, prototype, assemble and test precision support structures and tooling for the ATLAS ITk Pixel Outer Barrel. Implement and run quality assurance procedures and test benches, manage procurement and acceptance, and contribute hands-on to production, integration and installation of detector components and sub-assemblies.

Lead the editorial direction of CERN Courier, commission and edit feature articles, write news and features, manage the website and social media, supervise and mentor the editorial team, coordinate picture research, fact-checking and proofreading, and collaborate with production, marketing and other CERN teams.

The role involves advising on governance, risk, and compliance in IT, leading committees, coordinating workplans, and ensuring digital initiatives compliance.
