## Description

The Reliability Engineer is responsible for ensuring product reliability and system safety throughout the entire product lifecycle, from concept and design through manufacturing, production, and field deployment. This role partners cross-functionally to evaluate designs, execute reliability analyses and testing, investigate failures, and implement continuous improvements that enhance product performance and production readiness.

Essential Job Functions - Responsibilities:

 * Perform predictive reliability analyses, including MTTF/MTBF calculations, Weibull analysis, and reliability modeling to evaluate product performance and identify failure trends.
 * Lead Failure Modes & Effects Analysis (FMEA), Fault Tree Analysis (FTA), and root cause investigations to identify risks and drive corrective and preventative actions.
 * Develop and execute qualification, validation, environmental, and accelerated life testing plans to verify product reliability and production readiness.
 * Collaborate with engineering, manufacturing, quality, and test teams to improve product designs, manufacturing processes, and system reliability throughout development and production.
 * Support design reviews, manufacturing readiness activities, and the transition of products from development into production.
 * Develop maintainability models and support preventative maintenance and sparing strategies.
 * Create and improve standardized reliability processes, tools, and documentation to support product development and manufacturing.
 * Follow Business Technology policies to protect sensitive data and reduce information security occurrences.
