Senior Mechanical Delivery Engineer

• Serve as Lambda’s mechanical field engineering owner from construction completion through commissioning, cooling-system bring-up, and initial compute loading.
• Perform site walkdowns to verify installed mechanical systems against approved designs, P&IDs, specifications, submittals, and Lambda standards.
• Validate equipment installation, piping, supports, valves, instrumentation, insulation, maintenance access, system labeling, and flow direction.
• Confirm that redundancy, isolation boundaries, failure domains, bypasses, drains, vents, and maintenance provisions function as designed.
• Inspect central plants, chillers, cooling towers, dry coolers, pumps, heat exchangers, CRAHs, CDUs, liquid-cooling loops, and associated water systems.
• Review pressure-test, flushing, cleaning, filtration, water-treatment, balancing, and equipment-startup results.
• Identify installation deficiencies, design conflicts, and operational risks; document punch-list items and drive them through closure.
• Witness factory acceptance testing, site acceptance testing, functional performance testing, and integrated systems testing.
• Develop and review startup plans, MOPs, SOPs, EOPs, commissioning scripts, and mechanical safety controls.
• Troubleshoot flow, pressure, temperature, air-removal, fouling, water-quality, equipment, and controls issues during system bring-up.
• Confirm cooling capacity, water quality, control stability, redundancy, and monitoring are ready before GPU infrastructure is placed under load.
• Coordinate with design engineers, general contractors, mechanical trades, equipment manufacturers, commissioning agents, operations, and HPC deployment teams.
• Validate as-built documentation, test reports, equipment settings, commissioning records, and turnover packages before operational handoff.
• Capture field lessons and incorporate them into Lambda’s design standards, construction requirements, and site-validation playbooks.
• Mentor other engineers and provide senior technical leadership during high-risk startup and commissioning activities.

You

• Have significant experience delivering, commissioning, or operating mechanical systems in data centers, mission-critical facilities, central plants, or industrial environments.
• Understand hydronic systems, heat transfer, pumping, heat exchangers, heat rejection, air cooling, and liquid cooling.
• Can interpret P&IDs, equipment submittals, mechanical layouts, control sequences, test reports, and construction documentation.
• Have hands-on experience with site inspections, pressure testing, flushing, water treatment, testing and balancing, equipment startup, or commissioning.
• Understand mechanical redundancy, failure isolation, thermal ride-through, maintainability, and operational risk.
• Can determine whether installed systems are ready to safely support high-density compute loads.
• Understand construction safety, lockout/tagout, stored-energy hazards, and safe startup practices.
• Can make sound technical decisions in the field, escalate critical issues, and coordinate corrective work under schedule pressure.
• Communicate clearly with construction teams, engineers, vendors, operators, and senior stakeholders.
• Are willing to travel extensively and spend extended periods at active construction and commissioning sites.
• Hold a bachelor’s degree in mechanical engineering or equivalent practical experience.
