Heatcraft Worldwide Refrigeration is a long-standing leader in the world of commercial refrigeration, providing climate-control solutions to customers in more than 70 countries. Their state-of-the-art manufacturing facilities in the cities of Stone Mountain and Tifton, Georgia, produce evaporators, condensers, compressor racks, and other top-quality refrigeration products for their five market-leading brands: Bohn, Larkin, Climate Control, Chandler, and InterLink. Heatcraft products are primarily used to preserve food and other perishables in supermarkets, convenience stores, restaurants, warehouses and distribution centers, in addition to other applications such as data centers, pharmaceutical and industrial process cooling.

This Sr. Reliability Engineer supports the reliability, availability, and operational performance of data center cooling systems from commissioning through field operation. The role combines customer-facing reliability support, RCM, predictive maintenance (PdM), operational-data analytics, and system reliability modeling to reduce risk and improve uptime.

DUTIES INCLUDE BUT ARE NOT LIMITED TO:

• Partner with customers, Service, Commissioning, Engineering, Controls, and Quality to address reliability concerns, field issues, and operational needs.
• Lead RCM and PdM activities, including asset criticality, failure-mode evaluation, FRACAS, root-cause analysis, and preventive, predictive, and condition-based maintenance strategies.
• Analyze operational, alarm, maintenance, commissioning, warranty, and field data to identify degradation, recurring failures, and emerging reliability risks.
• Collect and utilize physics-based data from the Digital Twin, including what-if operating scenarios, to assess system health and support reliability analysis and PdM decisions.
• Utilize Weibull and BlockSim to simulate equipment and system reliability, availability, MTBF, MTTR, downtime, failure behavior, and N+X redundancy/failover performance.
• Evaluate system redundancy and N+X configurations, including single-point failures, failover behavior, backup capacity, recovery performance, and overall system availability.
• Develop Power BI reliability dashboards and track key metrics including availability, downtime, MTBF, MTTR, repeat failures, alarms, and asset health.
• Perform alarm rationalization and alarm analytics, linking alarms to failure modes, consequences, response priorities, and diagnostics.
• Translate customer, field, and reliability insights into actionable recommendations for maintenance, diagnostics, commissioning, service procedures, controls, and product design.

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Reliability Engineering, or a related engineering discipline.
• Experience in reliability engineering, field reliability, maintenance engineering, commissioning, or equipment performance analysis.
• Knowledge of RCM, PdM, FRACAS, root-cause analysis, preventive and condition-based maintenance, asset-health monitoring, and reliability metrics.
• Strong analytical, problem-solving, customer-facing, and cross-functional communication skills.

Preferred Experience

• Data center cooling, HVAC/refrigeration, CO2/HFC systems, or other mission-critical infrastructure.
• RCM and PdM applications using equipment condition, operational data, and asset-health indicators.
• Weibull and BlockSim reliability tools for simulation of availability, MTBF, MTTR, downtime, failure behavior, and system redundancy.
• Power BI reliability dashboards and operational analytics.
• SCADA, BMS, CMMS, or equipment monitoring systems.
• Alarm rationalization and alarm analytics.
• System redundancy and N+X configurations, failover, backup capacity, and high-availability assessment.
• Customer-facing commissioning, field reliability, or technical support.
