Data Centre Technical Engineer (IT-FCS-DC-2026-69-LD)

At CERN, the European Organization 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.

Introduction:

You will join the IT Department’s Fabric and Communication Systems (FCS) Group within the Data Centres (DC) Section, where you will contribute to the operation and support of CERN’s Data Centres and associated computing facilities. The section is responsible for managing the full lifecycle of computing equipment, as well as developing, maintaining, and integrating software applications with existing facility monitoring systems.

During CERN’s Accelerator Long Shutdown 3 (LS3) and beyond, you will support major data centre expansion and upgrade projects aimed at almost tripling the current hosting capacity, which is required to support future LHC runs and their increasing computing demands. Your role will focus on automating computing hardware diagnostics and improving repair service efficiency by implementing and enhancing operational procedures.

Functions:

• Develop and implement automation tools for hardware problem diagnostics to improve response times and operational efficiency.
• Work closely with other computing services to maintain and enhance the automated commissioning system for computing hardware.
• Provide and maintain clear procedures and guidelines to support the hardware repair team, ensuring efficient and consistent repair workflows.
• Support data centre expansion and upgrade projects, assisting with installation and testing of new equipment and decommissioning of obsolete hardware.
• Maintain accurate documentation of infrastructure assets, configurations, and procedures.
• Collaborate with IT teams, facilities staff, and external partners to deliver operational improvements and incident responses.

Bachelor's degree or equivalent relevant experience in the field of Computer Science, Information Technology or a related field.

Experience:

• Strong knowledge of server hardware, networking fundamentals, and data centre infrastructure.
• Proven problem-solving skills with the ability to perform well under pressure.
• Proficiency in Python and shell scripting for automation and diagnostics.
• Experience working with Linux operating systems including system administration.
• Familiarity with monitoring and management tools used in data centre environments.
• Excellent documentation skills with keen attention to detail.
• Strong communication skills and a collaborative team player mindset.
• Hands-on experience in data centre environments, automation frameworks, or computing hardware will be considered a strong asset.

Technical competencies:

• Knowledge of programming techniques and languages.
• Knowledge and deployment of computing hardware.
• Installation, operation and maintenance (preventive and corrective) of computing systems.

Behavioural competencies:

• Working in Teams: cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals.
• Achieving Results: delivering high quality work on time and fulfilling expectations.
• Solving Problems: testing solutions for long-term suitability, cross-checking with all concerned before implementation.

Language skills:

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