Data Center Infrastructure Mechanical Engineer

About the Role

The ideal candidate will have a deep understanding of thermal architecture, equipment development, manufacturing validation, construction, commissioning, deployment, and operations. You will be expected to translate evolving compute and rack-level thermal requirements into practical infrastructure designs, evaluate complex equipment and vendor solutions, and drive technical decisions across facilities, hardware, controls, telemetry, testing, commissioning, and operations.

What You Will Do

• Define mechanical and cooling infrastructure requirements and reference architectures for AI data center campuses, including heat rejection, chilled water, condenser water, liquid cooling distribution, air handling, containment, filtration, water treatment, controls, and metering.
• Review and develop basis-of-design documents, design narratives, P&IDs, mechanical schedules, equipment specifications, thermal capacity models, hydraulic models, CFD analysis, controls sequences, and commissioning requirements.
• Evaluate mechanical architectures for high-density compute, including direct-to-chip liquid cooling, CDU topology, facility water interfaces, manifolds, quick disconnects, hoses, heat exchangers, pumping strategies, leak detection, serviceability, and failure isolation.
• Partner with electrical, controls, hardware, networking, construction, and operations teams to ensure cooling systems support liquid-cooled GPU rack deployments and reliable facility operation.
• Develop technical specifications and acceptance criteria for chillers, cooling towers, dry coolers, evaporative coolers, pumps, heat exchangers, CDUs, manifolds, valves, filters, water treatment systems, CRAHs, air handlers, VFDs, controls panels, sensors, and monitoring devices.
• Lead technical evaluation of equipment vendors, manufacturers, design consultants, commissioning agents, contractors, and testing laboratories; review submittals, P&IDs, control diagrams, performance curves, test reports, certifications, and quality documentation.
• Drive factory acceptance testing, site acceptance testing, witness testing, pressure testing, leak testing, thermal performance testing, reliability testing, interoperability testing, and integrated systems testing for critical equipment and high-density rack deployments.
• Help design and operate a hardware and data center infrastructure R&D laboratory used to validate new cooling equipment, liquid-cooled GPU rack designs, operating envelopes, fault scenarios, telemetry, and facility-hardware interactions.
• Collaborate with hardware manufacturers to evaluate L10 and L11 test procedures, yield, throughput, reliability, serviceability, and readiness for large-scale deployment.
• Define telemetry and controls requirements for mechanical systems, including monitoring, alarming, and remote access.

What We Are Looking For

• 8+ years of experience in mechanical engineering, with a focus on data center or critical infrastructure design and operation.
• Deep hands-on experience with mission-critical mechanical systems, including chilled water plants, condenser water systems, cooling towers, dry coolers, pumps, heat exchangers, CDUs, manifolds, CRAHs, air handlers, filtration, water treatment, controls, and liquid distribution.
• Strong understanding of thermal architecture, thermal modeling, and CFD analysis.
• Experience with high-density rack cooling interfaces, including direct-to-chip liquid cooling and CDU topology.
• Excellent communication and collaboration skills, with the ability to work effectively with cross-functional teams.
• Strong problem-solving skills, with the ability to analyze complex problems and develop creative solutions.
• Experience with data center design and operation, including infrastructure planning, deployment, and maintenance.

Nice to Have

• Experience with data center infrastructure R&D, including laboratory design and operation.
• Knowledge of AI compute and machine learning applications, including hardware and software requirements.
• Familiarity with industry standards and best practices for data center design and operation, including ASHRAE, IEEE, and Uptime Institute.
• Experience with Agile development methodologies and version control systems, including Git and Jira.

Benefits and Perks

• Competitive salary and benefits package, including health insurance, retirement savings, and paid time off.
• Opportunities for professional growth and development, including training and education programs.
• Collaborative and dynamic work environment, with a team of experienced professionals.
• Flexible work arrangements, including remote work options and flexible hours.
• Access to cutting-edge technology and tools, including data center infrastructure and AI computing platforms.

• Be prepared to discuss your experience with thermal architecture, thermal modeling, and CFD analysis in the context of data center design and operation.
• Highlight your ability to collaborate effectively with cross-functional teams, including research, hardware engineering, data center engineering, supply chain, EHS, operations, and external delivery partners.
• Emphasize your problem-solving skills, including your ability to analyze complex problems and develop creative solutions.
• Show a deep understanding of the latest trends and technologies in data center design and operation, including high-density rack cooling interfaces and AI compute applications.
• Be prepared to discuss your experience with data center infrastructure R&D, including laboratory design and operation.
• Highlight your knowledge of industry standards and best practices for data center design and operation, including ASHRAE, IEEE, and Uptime Institute.
