Senior Reliability Engineer

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)
