Commissioning Engineer

Commissioning Engineer — AI Data Center Liquid CoolingSchedule: Two weeks onsite, followed by one week offsite, for candidates who do not wish to relocate. Relocation assistance is available for candidates interested in moving near a project site. Project locations: Pecos, TX; Fort Stockton, TX; and Point Pleasant, WV.Seeking Mechanical Commissioning Engineers to test the liquid cooling infrastructure supporting high-density AI and high-performance computing data centers. The primary focus is liquid-to-chip cooling and its supporting distribution systems. This field-based role supports Level 3 through Level 5 (L3–L5) commissioning, from installation verification and equipment startup through functional and integrated systems testing.ResponsibilitiesReview mechanical drawings, piping and instrumentation diagrams, equipment submittals, specifications, controls sequences, and commissioning scripts for liquid cooling systems.Walk down coolant distribution units (CDUs), manifolds, piping networks, valves, sensors, leak detection devices, and associated heat rejection connections. Identify installation deficiencies and incomplete work before startup.Coordinate with equipment manufacturers, contractors, and design engineers on startup procedures for direct-to-chip cooling systems and other project-specific liquid cooling equipment, including rear-door heat exchangers or immersion cooling systems where installed.Review flushing, pressure testing, water treatment, and testing, adjusting, and balancing (TAB) documentation where applicable. Verify that systems are ready for functional testing.Execute and document tests of coolant flow, differential pressure, temperature control, leak detection, alarms, and equipment response across the cooling distribution path.Verify CDU operation, controls, and transitions between normal and failure conditions according to approved sequences of operation and test scripts.Confirm that BMS points, graphics, alarms, and trends accurately represent equipment and sensor behavior observed in the field.Participate in IST with electrical and controls teams to verify cooling response during simulated power loss, pump or CDU failure, changes in thermal load, and recovery to normal operation.Record test results, investigate performance exceptions, maintain deficiency logs, verify corrective actions through retesting, and prepare commissioning reports and turnover documentation.Coordinate testing across mechanical, electrical, controls, construction, and equipment manufacturer teams while following site safety procedures.Required qualificationsAt least 2 years of mechanical commissioning experience, with the technical depth and responsibility appropriate to a mid- or senior-level position.Hands-on commissioning experience with data center cooling systems or complex liquid distribution and process cooling systems.Ability to read mechanical drawings, piping diagrams, specifications, test scripts, and controls sequences.Experience verifying flow, pressure, temperature, controls, alarms, and equipment response during startup or functional testing.Understanding of fluid distribution, heat transfer, and the importance of maintaining cooling availability to critical equipment.Strong field troubleshooting, documentation, and coordination skills.Preferred experienceDirect commissioning experience with CDUs, direct-to-chip cooling, manifolds, rear-door heat exchangers, or immersion cooling.Experience with liquid cooling piping networks, leak detection, water treatment, and BMS integration.Direct participation in L3–L5 commissioning or IST on AI, high-performance computing, or hyperscale data center projects.Experience developing test procedures and resolving performance deficiencies with equipment manufacturers and design engineers.Schedule and relocationCandidates who prefer not to relocate can work a two-week onsite, one-week offsite rotation at the project sites. Relocation assistance is available for candidates interested in moving near a project site.BenefitsCompany benefits include a competitive compensation package, career growth opportunities, performance incentives and bonuses, paid time off, and eligibility to enroll in a 401(k) plan. Medical, dental, vision, long-term disability, and short-term disability coverage are also available.
