Sr. Reliability Engineer

Lennox International•Stone Mountain, GA

1d•$99,000 - $130,200•Onsite

About The Position

The 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, reliability-centered maintenance (RCM), predictive maintenance (PdM), operational-data analytics, and system reliability modeling to reduce risk and improve uptime. The engineer works cross-functionally with customers and internal teams to address reliability concerns, field issues, and operational needs. The role analyzes system and equipment data, assesses asset health and system redundancy, develops reliability dashboards, and translates findings into recommendations for maintenance, commissioning, service procedures, controls, diagnostics, and product design. This is a salaried exempt position based in Stone Mountain, Georgia. The schedule is in-office Monday through Friday. The starting salary range is $99,000–$130,200 annually, and the position is eligible for the BroadBase Incentive program with a target payout of 2%.

Requirements

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.

Nice To Haves

Experience with 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.
Experience with Weibull and BlockSim reliability tools for simulating availability, MTBF, MTTR, downtime, failure behavior, and system redundancy.
Experience developing Power BI reliability dashboards and performing operational analytics.
Experience with SCADA, BMS, CMMS, or equipment monitoring systems.
Experience with alarm rationalization and alarm analytics.
Experience assessing system redundancy and N+X configurations, failover, backup capacity, and high availability.
Customer-facing commissioning, field reliability, or technical support experience.

Responsibilities

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 use physics-based Digital Twin data, including what-if operating scenarios, to assess system health and support reliability analysis and PdM decisions.
Use Weibull and BlockSim to simulate equipment and system reliability, availability, MTBF, MTTR, downtime, failure behavior, and N+X redundancy and 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 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.
