HQ.

The Senior Mechanical Engineer – Development will take ownership of the design, planning, execution, and delivery of advanced mechanical systems for developer‑led hyperscale data center projects across Europe. This role combines technical expertise in designing, testing, and optimizing mechanical systems, including HVAC, cooling infrastructure, fire suppression systems, and thermal load management, with project management skills to ensure on‑time, within‑budget, and compliant delivery across all project phases.

The successful candidate will act as a trusted technical advisor and project leader, collaborating with cross‑functional teams, external contractors, and tenants to deliver high‑performance, sustainable, and mission‑critical mechanical infrastructure tailored to meet operational demands and evolving industry standards.

• Serve as the subject matter expert for the design and delivery of mechanical systems that meet tiered reliability, scalability, and energy efficiency goals in hyperscale environments.
• Review detailed engineering specifications and calculations for HVAC systems, chilled water networks, air handling units, cooling towers, and fire suppression systems, ensuring compliance with regulatory standards.
• Optimize thermodynamic efficiencies and fluid dynamics across mechanical systems to achieve maximum performance and minimize operating costs.
• Review CFD modelling software to simulate airflow dynamics, thermal load distribution, and cooling efficiency, identifying potential hotspots and operational risks.
• Design redundant systems to support continuous operations during peak loads and maintenance windows.

• Lead mechanical scopes across all phases of development, including early‑stage development, design reviews, and tendering.
• Collaborate with development teams during pre‑construction planning, providing input on master plans, feasibility studies, and design risk mitigation.
• Manage mechanical system integration during construction, acting as the primary liaison between contractors, consultants, and the internal project team.

• Ensure all designs comply with European building codes, ASHRAE standards (e.g., TC9.9 for data centers), and ISO directives.
• Incorporate energy optimization technologies and carbon reduction strategies into designs, meeting enterprise sustainability objectives and achieving optimal PUE targets.
• Monitor adherence to environmental regulations, including waste management, material use, and emissions minimization.

• Partner with structural and electrical engineers to ensure seamless integration of mechanical systems with building designs and other infrastructure.
• Collaborate with tenant teams to address unique mechanical requirements, tailoring cooling and airflow solutions for their workloads.
• Build and maintain strong relationships with contractors, vendors, and consultants, ensuring project milestones and performance deliverables are consistently met.
• Lead design team meetings, presenting technical insights and ensuring actionable outcomes for mechanical scopes.
• Research emerging industry innovations, including liquid cooling, IoT‑controlled sensor technologies, and AI‑driven predictive maintenance tools, integrating them into Cloud
  
  HQ projects where feasible.
