Senior Reliability Engineer

Role Overview

• Define, own, and continuously mature Range's end-to-end reliability program, establishing standards, processes, and culture across engineering, manufacturing, and operations
• Build and maintain a reliability roadmap aligned with product development milestones and fleet growth targets
• Develop and deploy predictive reliability models leveraging field telemetry, sensor data, and historical failure data to anticipate failures before they occur
• Build reliability growth models (Duane, AMSAA/Crow) to track and project reliability improvement over the product lifecycle
• Apply statistical methods Weibull analysis, Monte Carlo simulation, regression modeling to quantify failure risk and remaining useful life (RUL) of critical components
• Establish and monitor fleet-level KPIs including MTBF, MTTR, availability, failure rate, and warranty cost trends
• Define and lead DFMEAs to proactively identify and mitigate failure modes across systems to minimize costs and enhance customer satisfaction
• Define and enforce reliability requirements at the system, subsystem, and component level for Class 8 powertrain, chassis, and vehicle integration applications
• Conduct reliability allocation and reliability block diagram (RBD) modeling to ensure top-level uptime targets are achievable by design
• Champion reliability-centered design decisions including redundancy strategies, derating, and materials selection appropriate for heavy-duty trucking environments
• Author and maintain master Test Plans covering scope, objectives, resources, schedules, entry/exit criteria, and risk, ensuring alignment across engineering, program management, and leadership stakeholders
• Develop and execute comprehensive testing protocols including environmental (temperature, humidity, thermal shock, vibration, dust/water ingress), durability, fatigue, load, and accelerated life testing (ALT) tailored to Class 8 operating conditions
• Build Usage Profiles and Mission Profiles that accurately represent real-world Class 8 duty cycles long-haul, regional, and vocational and translate them into lab-equivalent test specifications
• Define and manage the Design Verification Plan and Report (DVP&R) for all major systems and subsystems, ensuring full traceability from requirements through test evidence
• Develop Production Validation Testing (PVT) plans to confirm that manufacturing processes do not degrade reliability relative to design intent
• Lead investigations into product failures, perform root cause analyses using 8D, Fishbone, 5-Why, and FTA methodologies, and implement corrective actions to prevent recurrence
• Maintain a living failure database and lessons-learned repository to capture institutional knowledge and inform future designs
• Create detailed reports, including DVP&Rs, test reports, failure analysis summaries, and reliability scorecards, to document testing procedures, results, and corrective actions
• Participate in design reviews and contribute to the development of supplemental design documentation such as assembly instructions, test reports, and cost analyses
• Support continuous improvement initiatives by leveraging field and test data to drive design iteration and product upgrades

Requirements

• 7+ years of experience in reliability engineering or a related role in automotive/heavy trucking
• Proficiency in reliability testing methodologies and data analysis techniques including DVP&R, ALT, DFMEAs, and HALT/HASS
• Strong problem-solving skills with the ability to conduct thorough root cause methodologies (8D, 5-Why, FTA, Fishbone, etc.)
• Excellent communication skills, both verbal and written, with the ability to collaborate across engineering disciplines and business functions
• Ability to work on-site in a dynamic environment, with hands-on involvement on the build floor
• Comfortable working across hardware, software, and operations teams in a fast-paced, hands-on environment
• Bachelor’s degree in Mechanical Engineering or a related field
