The Role

As a Senior Data Centre Design Engineer, you will act as a technical authority throughout the full lifecycle of data centre projects, from site assessment and engineering design reviews through to commissioning, operational support, upgrades, and optimisation initiatives. You will work closely with both internal stakeholders and external partners including colocation providers, consultants, contractors, and vendors to ensure the highest engineering standards are maintained across regional deployments.

Key Responsibilities

• Design & Engineering
  • Evaluate and review colocation opportunities, engineering documentation, and proposed facility designs.
  • Assess technical solutions, equipment submissions, and infrastructure designs against engineering standards and operational requirements.
  • Develop site-specific fit-out and infrastructure solutions for new and existing facilities.
  • Collaborate with network, security, operations, and EHS teams to ensure cross-functional requirements are incorporated into project designs.
  • Provide technical expertise relating to lease agreements, service levels, and infrastructure requirements.
• Project Delivery & Commissioning
  • Act as the engineering representative for major regional projects.
  • Coordinate technical activities across internal and external stakeholders.
  • Review and improve commissioning procedures, testing methodologies, and technical documentation.
  • Support testing and commissioning activities, ensuring issues are identified and resolved effectively.
  • Lead technical acceptance processes and support successful handover into operations.
• Operational Support
  • Maintain engineering documentation including design drawings, as-built documentation, and technical records.
  • Support operations teams with incident investigations, root cause analysis, and corrective action planning.
  • Drive infrastructure upgrades, retrofits, and optimisation projects to improve reliability, efficiency, and scalability.

About You

You will have:

• A degree in Electrical Engineering, Mechanical Engineering, Building Services Engineering, or a related discipline.
• Experience designing, constructing, commissioning, or operating mission-critical facilities, data centres, or colocation environments.
• Strong knowledge of critical infrastructure systems including electrical power distribution, cooling and HVAC systems, fire protection systems, and MEP infrastructure.
• Experience working with commissioning, testing, and operational acceptance processes.
• Excellent stakeholder management and communication skills.
• Knowledge of European building regulations, engineering codes, permitting requirements, and compliance standards.
• Chartered Engineer status or professional engineering registration would be advantageous.
• Fluency in English. Additional European languages would be beneficial.
• Ability and willingness to travel across Europe (approximately 30%).

What's On Offer?

• The opportunity to work on some of Europe's largest and most technically advanced data centre programmes.
• Exposure to large-scale, international infrastructure projects.
• A collaborative, fast-paced engineering environment.
• Significant opportunities for career growth within a global technology organisation.

If you're passionate about mission-critical infrastructure and want to help shape the future of cloud and data centre technology across Europe, we'd love to hear from you.
