Description
Job Description:
Job Summary: As the Senior Reliability Engineer, you will lead reliability engineering activities across Array Technologies’ solar tracker products, supporting both New Product Introduction (NPI) and sustaining engineering efforts. This role is responsible for improving long-term product durability, performance, safety, and lifecycle cost through structured reliability methodologies, testing, and cross-functional collaboration.
The Senior Reliability Engineer will drive reliability strategy including Design Failure Mode and Effects Analysis (DFMEA), reliability modeling, accelerated testing, field performance analysis, and validation planning. This role will work closely with Engineering, Quality, Manufacturing, and Program Management to improve product robustness and reduce failure risk throughout the product lifecycle. This position plays a critical role in improving customer satisfaction, reducing warranty exposure, and supporting the development of reliable products for demanding outdoor environments.
This position reports to the Director of Reliability.
Key Responsibilities
Reliability Engineering & Analysis
Lead DFMEA development and continuous improvement for new and existing products
Support Design for Reliability (DFR) during product development and NPI
Develop and maintain reliability models, including MTBF, RBD, Weibull, and failure trend analysis
Define reliability requirements and targets at system, subsystem, and component levels
Establish and monitor reliability KPIs (field failures, warranty trends, product degradation, customer returns)
Participate in design reviews and provide risk‑based reliability recommendations
Testing & Validation
Develop and execute reliability test strategies, including HALT/HASS, ALT, environmental, fatigue, corrosion, thermal cycling, and mechanical loading tests
Support Design Verification Plans & Reports (DVPRs) and qualification planning
Define statistically appropriate sample sizes and confidence levels for validation testing
Coordinate and oversee internal and third‑party laboratory testing
Analyze test results and recommend design improvements to enhance durability and performance
Warranty & Field Performance
Analyze field failures, customer returns, and warranty trends to identify systemic reliability issues
Develop and maintain warranty forecasting inputs and support reserve modeling
Partner with Finance, Quality, and Engineering to improve warranty prediction accuracy
Feed field performance lessons learned back into product development
Root Cause Analysis & Continuous Improvement
Lead or support structured root cause investigations (8D, FTA, Weibull)
Support corrective and preventive actions (CAPA) for recurring failures
Improve reliability processes, data collection, and reporting practices
Develop reliability dashboards and performance metrics as needed
NPI & Cross‑Functional Collaboration
Integrate reliability engineering into stage‑gate product development processes
Partner with Design Engineering to improve product robustness early in design
Support Sustaining Engineering with field issue resolution and design improvements
Collaborate with Manufacturing and Quality on recurring performance issues
Provide reliability input for new technology evaluations and product changes
Standards & Compliance
Support qualification activities aligned with UL, IEC, ASTM, and ISO standards
Assist with certification testing and technical documentation
Stay current on evolving standards related to solar tracker systems and outdoor structural applications
Leadership & Strategy
Establish and standardize reliability engineering processes, tools, and best practices
Mentor engineers and cross‑functional teams on reliability principles
Contribute to long‑term reliability strategy and roadmap development
Support growth of the Reliability function as business needs evolve
Qualifications
Required
Bachelor’s degree in Mechanical Engineering, Materials Science, Reliability Engineering, or a related field
5+ years of experience in reliability, product development, validation, or quality engineering within a mechanical or electromechanical environment
Experience with DFMEA, reliability modeling (MTBF, Weibull, RBD), root cause analysis, validation testing, and accelerated life testing
Experience working within structured NPI or stage‑gate development processes
Familiarity with reliability testing methods and environmental qualification practices
Strong technical communication skills, including reports, presentations, and executive summaries
Experience analyzing field performance data to drive engineering decisions
Preferred
Master’s degree in Engineering or a related discipline
Experience in renewable energy, solar, heavy equipment, automotive, or outdoor mechanical systems
Familiarity with corrosion mechanisms and environmental degradation
Experience with statistical software (Minitab, Reliasoft, JMP)
Familiarity with structural systems, including fasteners, bearings, drivetrains, actuators, torque tubes, and mechanical joints
Six Sigma certification (Green or Black Belt) or Certified Reliability Engineer (CRE)
