• Engineering support to site selection, new site development and project initiation.
• Provide engineering inputs and review of early-stage planning, Campus Master-Planning and Test-Fit Designs to assure validity of business objectives and design assumptions for site acquisition and investment decision making.
• Represent Vantage Data Centers as a technical authority with hyperscale customers, investors, and other corporate stakeholders.
• Lead on all mechanical engineering elements of EMEA Product Requirements, Guidelines and Standards, managing product change for all mechanical change requests, incorporating evolving liquid cooling and AI requirements.
• Develop and lead updates to the mechanical design standards and specifications to incorporate lessons, value engineering, consistency and system reliability.
• Lead on the development of the standardized and optimized mechanical equipment in the OFCI inventory program and actively support the OFCI procurement teams with technical advice and direct collaboration with vendors.
• Creation and evaluation of high value engineering and innovation ideas, and provide recommendations based on business-related cost-benefit analyses.
• Proactively engage with internal and external partners, to identify and exploit lessons to implement good ideas and resolve recurring issues.
• Deliver mechanical designs using DfMA principles, focusing on modular, standardized, and prefabricated solutions (HVAC, cooling, pipework, etc.).
• Support development of fungible building blocks, enabling scalable and repeatable design across projects.
• Run CFD studies to assess airflow, heat transfer, and system performance under different operating conditions.
• Equip Project Mechanical Engineers with the necessary knowledge, processes, and tools. Support and assure the high-quality delivery of mechanical and fire protection requirement setting, design and review.
• Hold regular meetings with Project and Global Innovation Mechanical Engineers to facilitate knowledge sharing and continuous improvement.
• Ensure all designs are fully coordinated by checking interfaces with other disciplines (sustainability, electrical, structural, architectural, etc.).
• Align mechanical solutions with broader stakeholder requirements, including client, operations, and construction teams.
• Either reactively or proactively, conduct short secondments to project teams to support, assure and reinforce when requested to do so.

Skills, Knowledge, and Experience

• Bachelors Degree in Mechanical Engineering, or similar technical field, from an accredited university or college desirable.
• Accredited engineering credentials preferred (Chartered / Professional Engineer).
• 10+ years of experience as a mechanical engineer with a strong focus on data center or mission critical environments.
• Experience in EMEA construction markets is required.
• Working knowledge of critical cooling infrastructure and critical power infrastructure within a data center project.
• Knowledge of control logic and feedback loops in HVAC.
• Strong knowledge of data center metrics (pPUE, ASHRAE allowable temperatures etc.) and drivers.
• Working knowledge of building and fire code standards.
• Willingness to travel (typically once or twice a month, for up to 3 days at a time).
