* Requires up to 25% domestic and/or international travel (rare)

• Experience designing and integrating hydronic systems including pumps, piping networks, valves and heat exchangers for data centre cooling applications.
• Knowledge of fluid dynamics, pressure drop calculations and pipe sizing for chilled water and glycol‑based systems.
• Understanding of installation constraints, maintenance access and serviceability in large‑scale mechanical infrastructure.
• Design and develop mechanical frames, enclosures and support structures for data centre power and cooling products (UPS systems, battery racks, CRAC units, containment systems, LVS, MVS).
• Perform advanced structural analysis using FEA tools to validate mechanical integrity under static, dynamic, seismic and thermal loads.
• Analyze load paths, stress concentrations, and fatigue life of structural components to ensure long‑term reliability.
• Design metal enclosures with considerations for airflow, thermal containment, EMI shielding and environmental protection.
• Evaluate and implement new materials, coatings and fabrication technologies to enhance product performance and reliability.
• Participate in customer engagements and site visits to understand deployment constraints and gather feedback for design improvements.
• Create detailed CAD models and fabrication drawings, including weldments, sheet metal and machined parts.
• Select appropriate materials and fabrication methods to optimise cost, performance and reliability.
• Collaborate with electrical, thermal and systems engineering teams to integrate mechanical designs with functional components.
• Lead mechanical design reviews and contribute to cross‑functional design validation efforts.
• Develop and maintain design documentation including BOMs, specifications, test plans and engineering change orders (ECOs).
• Drive continuous improvement in mechanical design for manufacturability (DFM), cost reduction and performance optimisation.
• Interface with suppliers and customers to resolve fabrication issues and ensure quality standards are met.
• Support lifecycle management of mechanical components, including obsolescence planning and alternate sourcing.
• Conduct root cause analysis and corrective actions for mechanical failures or field issues.
• Ensure mechanical designs support airflow management, thermal containment and integration with cooling systems (in‑row cooling, rear door heat exchangers).
• Collaborate with compliance and certification teams to ensure mechanical designs meet global regulatory requirements (UL, CE, RoHS, REACH).
