A Reliability Engineer is a professional who focuses on ensuring that products and systems perform consistently and dependably over time. They analyze potential failures, conduct tests, and develop strategies to improve the reliability of equipment and processes. Their work is crucial in industries such as manufacturing, aerospace, and electronics, where safety and performance are paramount. To achieve their goals, Reliability Engineers often use tools and methodologies like Failure Mode and Effects Analysis (FMEA) and Root Cause Analysis (RCA). They collaborate with other engineers and teams to implement improvements and monitor performance, ultimately enhancing customer satisfaction and reducing costs associated with failures.
