Job Description

  • Lead the design and delivery of mechanical building services upgrades within live data centre environments, including M&E upgrades, capacity increases, technology refreshes, phased refurbishments, and lifecycle replacements.

  • Develop and manage retrofit-specified design strategies, including tie-ins to live systems, redundancy planning, outage and staging strategies, and resilience design.

  • Conduct or oversee technical due diligence of existing data centre facilities, including capacity unlock assessments (power, cooling, and white space).

  • Prepare and review detailed design drawings, schematics, schedules, technical reports, and tender documentation.

  • Manage project scope, budget, programme, and contracts - identifying and mitigating scope creep, risks, and live-environment constraints.

  • Liaise directly with clients (hyperscale, colocation, and enterprise operators), contractors, and vendors to ensure project goals are achieved with zero operational disruption.

  • Drive quality assurance and governance across all assigned projects, adhering to WAP/PTW protocols in live environments.

  • Mentor and support the development of junior engineers and graduate staff within the retrofit workstream.

  • Support business development by contributing to proposals, client presentations, and technical strategies for retrofit opportunities across EMEA.

  • Champion innovation in live-environment engineering and contribute to the continuous improvement of Ethos' retrofit delivery model.

  • Lead phasing strategy for live cooling and HVAC upgrades, ensuring continuity of critical mechanical infrastructure throughout delivery.


Requirements

  • Bachelor's or Master's degree in Mechanical Engineering or a related discipline.

  • Minimum 8 years' experience in building services engineering, with at least 3 years focused on data centre or mission-critical projects.

  • Demonstrable experience working in live, operational data centre environments - including brownfield upgrades, M&E replacements, or phased refurbishments.

  • Chartered Engineer status (or actively working towards Chartership) with Engineers Ireland or equivalent.

  • Proven track record managing multi-million-euro MEP projects from concept to completion.

  • Strong understanding of Irish and EU building regulations; knowledge of LEED/BREEAM and the EU Energy Efficiency Directive is an advantage.

  • Strong expertise in mechanical systems design for live data centre environments, including chilled water plant, CRAC/CRAH upgrades, air handling units, in-row cooling, and fire suppression systems.

  • Experience delivering M&E upgrades within operational facilities - including tie-ins to live plant, outage management, and resilience planning.

  • Proficient in AutoCAD, Revit MEP, Bluebeam, and Microsoft Office; working knowledge of IES, HAP, or similar mechanical analysis tools is advantageous.

  • Strong knowledge of CIBSE, ASHRAE, BS, IS, and EN standards applied in retrofit and live-environment contexts.

  • Understanding of PUE optimisation and cooling efficiency improvements to meet EU Energy Efficiency Directive targets and client ESG requirements.

  • Familiarity with commissioning and integration of mechanical systems within live, mission-critical facilities.


Core Competencies

Demonstrates expertise in mechanical systems design and project management within live data centre environments, focusing on M&E upgrades, resilience planning, and compliance with building regulations.
