Reliability Engineer

XNRGY Climate Systems is a North American leader in the sustainable design and advanced manufacturing of custom air-treatment, thermal-management, and liquid-cooling systems. With decades of HVAC engineering and manufacturing expertise, XNRGY delivers innovative, energy-efficient solutions for mission-critical industries, including hyperscale and modular data centers, healthcare, clean rooms, life sciences, semiconductors, and advanced manufacturing.

Our United States technology headquarters and manufacturing facility opened in Mesa, Arizona, in 2025. As XNRGY continues building its Service and Commissioning organization, we are seeking an experienced Reliability Engineer to support our growing installed base of chillers, computer room air handlers (CRAHs), and fan coil wall systems.

One position will be weighted toward chillers and refrigeration, while the other will focus more heavily on air-side equipment, electrical systems, and controls. Both positions carry the same core responsibilities, and product alignment will be based on each candidate’s experience.

The Reliability Engineer is responsible for investigating field failures, determining their causes, developing corrective actions, and helping ensure that the same issue does not affect future units.

Working within Service Engineering, this position serves as a critical link between field teams and XNRGY’s Engineering, Manufacturing, Quality, Supply Chain, and Service Operations functions. The Reliability Engineer will lead warranty and defect investigations, manage service-parts data, provide senior technical escalation support, and translate field findings into product, process, and documentation improvements.

This is an opportunity to help build the systems used to support XNRGY’s growing mission-critical installed base. The investigation standards, service-parts structure, and escalation processes are being developed now, and the Reliability Engineer will play a central role in establishing them.

Field data, technical investigations, and product changes operate within one organization, creating a direct path from an equipment failure in the field to a verified corrective action on the production line.

• Department: Service Engineering—Liquid Cooling & Mission Critical

• Reports to: Manager, Service Engineering

• Location: Mesa, Arizona

• Employment type: Full-time

• Travel: Approximately 30%, with periods of higher travel during significant field investigations

• Openings: Two

• Product lines: Chillers, CRAH units, and fan coil wall systems

• Lead investigations into field failures as a member of the Warranty and Defect Investigation Team, from the initial field report through verified corrective-action closure.

• Conduct structured root-cause analysis using 8D, five-whys, fault-tree analysis, failure mode and effects analysis, or another method appropriate to the problem.

• Produce investigation reports that can withstand review by customers, suppliers, engineering teams, and warranty stakeholders.

• Present findings and open actions to the Field Defect Committee.

• Maintain an accurate action log that clearly distinguishes completed actions from unresolved items.

• Determine whether failures result from design issues, manufacturing escapes, supplier defects, transit damage, installation conditions, or service errors.

• Support cost recovery when evidence shows that responsibility falls outside XNRGY.

• Analyze failures at the population level to identify patterns before they develop into larger service campaigns.

• Build and maintain the service bill of materials for assigned product lines.

• Define which components are field-replaceable, the appropriate replacement level,…
