Résumé du poste

Clear. in London seeks a Senior Manager, Mechanical Design to act as the mechanical technical authority for the EMEA region, defining and governing standards for a leading European data centre platform.

You will own the cooling strategy, plant standards, thermal performance and energy efficiency, guiding regional design teams to scalable, commercially optimised solutions. You will collaborate with cross-functional groups on complex projects, challenge consultant designs, and drive future-ready,

Qualifications

• Significant experience in mechanical engineering within mission-critical, hyperscale data centre or similarly complex technical environments.
• Deep technical expertise across chilled water systems, plant optimisation, air-cooled and hybrid cooling solutions, liquid cooling integration, thermal modelling, and capacity planning.
• Strong understanding of data centre cooling strategy, resilience, scalability, energy efficiency and PUE optimisation.

Responsabilités

• Act as the senior mechanical technical authority across EMEA, defining and maintaining the mechanical components of the European Reference Design and future iterations.
• Own the mechanical cooling strategy and plant standards, including air-cooled solutions, chilled water systems, liquid cooling integration, and hybrid deployment approaches.
• Define modular mechanical building block principles that support scalability, phasing flexibility, resilience, and the platform’s core design philosophy.
• Provide senior technical review at key RIBA stage gates, challenging consultant designs for compliance with standards, energy efficiency, constructability, and operability.
• Review and approve structured deviations from mechanical standards, ensuring design decisions are clearly governed, documented, and aligned with platform objectives.
• Support regional design and delivery teams with complex mechanical issues during design, PCSA, construction, and commissioning phases.
• Provide technical input into client specification reviews and support structured responses to changes in rack density, inlet temperatures, flow rates, and other hyperscale requirements.
• Monitor emerging cooling technologies, higher-density deployments, and AI-driven load growth, helping define a future-ready roadmap for liquid cooling and next-generation mechanical systems.
• Support sustainability and energy optimisation initiatives, including plant sizing, PUE performance, capacity planning, and improvements that enhance MW yield and platform competitiveness.
• Partner with commercial, development, and investment teams to explain mechanical CapEx drivers, quantify the impact of specification changes, and support informed decision-making.
• Develop and maintain mechanical design standards, technical guidance notes, Basis of Design alignment, QA checklists, peer review frameworks, and BIM-related mechanical requirements.
• Translate complex mechanical engineering topics into clear, practical insight for senior stakeholders, regional teams, and cross-functional partners.

Description du poste

As Senior Manager, Mechanical Design, you will be a senior mechanical technical authority within the EMEA Design & Engineering function, helping define, govern, and continuously improve the mechanical engineering standards that shape a leading European data centre platform.

You will own key elements of the organisation's cooling strategy, mechanical plant standards, thermal performance, and energy efficiency approach, ensuring the European Reference Design is applied consistently across regions while remaining scalable, commercially optimised, and ready for future customer requirements.

Working closely with Engineering, Design, Development, Delivery, Commercial, Construction, Commissioning, and regional project teams, you will bring senior technical oversight, practical challenge, and clear guidance to complex mission-critical data centre projects across EMEA.

Key Responsibilities

• Act as the senior mechanical technical authority across EMEA, defining and maintaining the mechanical components of the European Reference Design and future iterations.
• Own the mechanical cooling strategy and plant standards, including air-cooled solutions, chilled water systems, liquid cooling integration, and hybrid deployment approaches.
• Define modular mechanical building block principles that support scalability, phasing flexibility, resilience, and the platform’s core design philosophy.
• Provide senior technical review at key RIBA stage gates, challenging consultant designs for compliance with standards, energy efficiency, constructability, and operability.
• Review and approve structured deviations from mechanical standards, ensuring design decisions are clearly governed, documented, and aligned with platform objectives.
• Support regional design and delivery teams with complex mechanical issues during design, PCSA, construction, and commissioning phases.

• Translate complex mechanical engineering topics into clear, practical insight for senior stakeholders, regional teams, and cross-functional partners.

What You'll Bring

• Significant experience in mechanical engineering within mission-critical, hyperscale data centre, or similarly complex technical environments.
• Deep technical expertise across chilled water systems, plant optimisation, air-cooled and hybrid cooling solutions, liquid cooling integration, thermal modelling, and capacity planning.
• Strong understanding of data centre cooling strategy, resilience, scalability, partial-load and full-build-out assumptions, energy efficiency, and PUE optimisation.
• Experience reviewing and challenging consultant designs, leading technical governance, and reducing design changes during construction.
• Commercial awareness, with the ability to balance energy performance, CapEx efficiency, expandability, MW yield, and long-term platform value.
• Confidence working across regional and cross-functional teams, including Design, Engineering, Development, Delivery, Commercial, Construction, and Commissioning.
• Strong communication skills, with the ability to turn technical complexity into clear recommendations for technical, commercial, and executive audiences.
• A degree or equivalent experience in Mechanical Engineering. Chartered status, or progress towards chartership, would be advantageous.
• Experience in a developer, hyperscale, investor-backed, or large-scale infrastructure platform would be beneficial.
• A structured, collaborative, and improvement-focused approach, with the judgement to make clear decisions under pressure.

What Is Offered

• Opportunity to work on critical digital infrastructure, supporting the development and operation of advanced data centre environments.
• Long-term career progression with exposure to large-scale projects and professional growth across an expanding European platform.
• Competitive compensation and benefits package designed to support you both professionally and personally.
