Sr. Reliability Engineer

Lennox International•Stone Mountain, GA

15h•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 partners with customers and internal Service, Commissioning, Engineering, Controls, and Quality teams to address reliability concerns, field issues, and operational needs. The role leads RCM and PdM activities, analyzes operational and maintenance data, uses Digital Twin physics-based data and what-if scenarios, and applies Weibull and BlockSim tools to assess equipment and system reliability. It also evaluates redundancy and failover configurations, develops Power BI dashboards, performs alarm analytics, and converts field and customer insights into recommendations for maintenance, diagnostics, commissioning, service procedures, controls, and product design. This is a salaried exempt position based in Stone Mountain, Georgia. The role is in the office Monday through Friday and is eligible for a target BroadBase Incentive payout of 2%. The stated starting salary range is $99,000 to $130,200 annually. Employees in this role are not eligible for overtime.

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.
Experience applying RCM and PdM using equipment condition, operational data, and asset-health indicators.
Experience with Weibull and BlockSim reliability tools for simulation of availability, MTBF, MTTR, downtime, failure behavior, and system redundancy.
Experience with Power BI reliability dashboards and operational analytics.
Experience with SCADA, BMS, CMMS, or equipment monitoring systems.
Experience with alarm rationalization and alarm analytics.
Experience evaluating 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 data from the Digital Twin, 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.
