Mechanical Engineer

• 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-specific 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.

Senior Project Engineer – Mechanical, Data Centre Retrofit

• Lead the design and development of structural and general mechanical systems for Manna’s aircraft platforms.
• Own mechanical design work from concept through CAD, analysis, prototype build, test, design release, and production support.
• Design airframe structures, brackets, interfaces, mechanisms, enclosures, and integrated mechanical systems.
• Analyse structures under static, dynamic, vibration, fatigue, thermal, and operational loading conditions.
• Use CAD, FEA, CFD, hand calculations, and test data to make clear engineering decisions.
• Drive lightweight, robust, manufacturable design solutions that meet aircraft-level performance and safety requirements.
• Apply DFM/DFA principles across machined parts, sheet metal, composites, moulded components, additive parts, and assemblies.
• Conduct tolerance analysis and apply GD&T to ensure repeatable, production-ready designs.
• Develop and support mechanical test plans, DVPs, test rigs, validation builds, and data analysis.
• Work closely with manufacturing, quality, supply chain, electrical engineering, software, test, and operations teams to resolve system-level challenges.
• Support suppliers and manufacturing partners to ensure parts are scalable, cost-effective, and production ready.
• Lead root cause investigations and corrective actions for mechanical issues found during build, test, or operation.
• Mentor junior engineers and contribute to stronger design standards, better reviews, and improved engineering practices.
