## Description

Develop, coordinate and conduct technical reliability analyses and evaluations for hardware using MIL-HDBK-217F or equivalent and software reliability analysis using IEEE STD 1633-2016 or equivalent as guides using Windchill Risk & Reliability or Reliasoft package (Lambda Predict, BlockSim) software

Develop coordinate and conduct Failure Modes Effects and Criticality Analysis (Functional, Interfaces, and Part-Level) using MIL-STD-1629 for hardware as a guide at the launch vehicle system

Develop coordinate and conduct Fault Tree Analysis (FTA) for hardware systems using Windchill Risk & Reliability software

Support evaluation of launch vehicle systems and associated Built in Test (BIT) hardware / software to maximize failure mode test coverage and minimize potential for BIT false alarm

Evaluate and score hardware/software nonconformance reports to identify failures and use the data to calculate acceptance screening and corrective action effectiveness values and perform/support demonstrated reliability assessments.

Coordinate with various engineering organizations to assign and plan the methods and detailed activities to demonstrate required product reliability performance.

Analyze customer requirements and manage cost/schedule to develop reliability engineering programs to achieve company, customer and government agency reliability objectives.
