Job summary

Molex is seeking a Reliability Engineer to support development of next-generation WSS products for advanced optical networking systems. You will develop reliability strategies, design and execute tests, and collaborate across optics, mechanics, electronics, and manufacturing teams to ensure field-ready performance.

Responsibilities include planning qualification testing, performing data analysis, leading FMEA, and driving Design for Reliability throughout product development.

Qualifications

• Bachelor's degree in mechanical engineering, electrical engineering, materials science, physics, optical engineering, or a related engineering discipline.
• Experience in product reliability engineering, design engineering, and/or new product development.
• Experience planning and executing environmental testing and accelerated life testing.
• Experience performing root cause investigations using structured problem-solving methodologies.
• Strong understanding of statistical analysis and experimental design.
• Excellent written and verbal communication skills.
• Ability to work effectively on multidisciplinary engineering teams.
• Strong analytical and critical thinking skills.
• Curiosity and passion for understanding product failure mechanisms.

Responsibilities

• Develop product reliability and qualification strategies from concept through production release.
• Create reliability test plans based on customer requirements, industry standards (including Telcordia), and product-specific risk assessments.
• Design, execute, and oversee accelerated life testing, environmental stress testing, and reliability de-risk activities.
• Identify potential reliability risks early in development and define validation plans to mitigate technical risk.
• Partner closely with optical, mechanical, electrical, manufacturing, process, and quality engineers to implement Design for Reliability (DfR) throughout product development.
• Participate as a key stakeholder during design reviews to influence architecture, material selection, manufacturing processes, and component selection from a reliability perspective.
• Perform statistical analysis of reliability and life test data to evaluate product performance and predict field reliability.
• Collaborate with program management, sourcing, manufacturing, and logistics teams to support prototype builds, qualification testing, and rapid product iteration.
• Communicate technical findings, recommendations, and risk assessments through clear written reports and engineering presentations.
• Plan, conduct, and analyze complex reliability qualification testing for optical products and high-risk components.
• Develop test methods and qualification plans using Telcordia, customer, and internal reliability standards.
• Lead Failure Modes and Effects Analyses (FMEA), risk assessments, and reliability reviews throughout product development.
• Perform root cause investigations on prototype, qualification, and production failures using structured problem-solving methodologies.
• Coordinate laboratory failure analysis activities and drive corrective and preventive actions with cross-functional engineering teams.
• Develop statistical models for accelerated life testing and reliability prediction, including life distribution analysis and field life estimation.
• Support qualification of new materials, suppliers, manufacturing processes, and components.
• Drive continuous improvements in reliability methodology, testing capability, and engineering best practices.
