A professional who analyzes preliminary engineering-design concepts of major product, such as aircraft, naval vessel, or electronic communication or control system to recommend design or test methods for attaining customer-specified operational reliability, using knowledge of reliability engineering and other technologies. Responsibilities include:

• Analyzes preliminary plans and develops reliability engineering program to achieve customer reliability objectives.
• Analyzes projected product utilization and calculates cumulative effect on final system reliability of individual part reliabilities.
• Drafts $T3failure mode and effect analysis$T1 sheets or formulates $T3mathematical models,$T1 using computer-aided engineering equipment, to identify units posing excessive failure risks and support proposed changes in design.
• Enters data to simulate electrical inputs, transient conditions, temperature, stress, and other factors to develop computer models, and analyzes and adjusts design to predict and improve system reliability.
• Advises and confers with engineers in design review meetings to give reliability findings and recommendations.
• Determines units requiring environmental testing and specifies minimum number of samples to obtain statistically valid data.
• Reviews subcontractors' proposals for reliability program and submits evaluation for decision.
• Reviews engineering specifications and drawings, proposing design modifications to improve reliability within cost and other performance requirements.
• Observes conduct of tests at supplier, plant, or field locations to evaluate reliability factors, such as numbers and causes of unit failures.
• Monitors failure data generated by customer using product to ascertain potential requirement for product improvement.
