Job description

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU. If you'd like to build the world's best AI cloud, join us. What You’ll Do - 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. Nice to Have - Experience commissioning hyperscale, colocation, HPC, or AI data centers. - Experience supporting direct-to-chip liquid cooling, CDUs, technology cooling-water loops, or multi-megawatt GPU deployments. - Knowledge of coolant chemistry, glycol systems, filtration, flushing, passivation, corrosion control, and materials compatibility. - Familiarity with Level 1–5 commissioning and integrated systems testing. - Experience using Procore, Bluebeam, commissioning-management platforms, or building-automation trend data. - Experience investigating cooling failures and leading root-cause analysis. - Professional Engineer licensure, commissioning certification, or testing-and-balancing certification.
