Developing test plans, test objectives and schedules consistent with requirements and timelines; leading daily test operations and generating test reports.
Autonomously leading risk assessment analyses and defining mitigation actions to ensure personnel and hardware safety during all test campaigns.
Interpreting P&IDs and generating test sequences, balancing the risk, needs of the test and the limits of the test bench and test article.
Working hand in hand with development engineers, test bench team, AIT team and external partners to support all test operations on internal and external test facilities.
Supporting rapid test data processing with component development engineers to guide the remainder of the test campaign and plan future test campaigns.
Defining, developing and updating test procedures and guidelines to improve test operations.
Preparing technical documentation, including detailed procedures, test reports, design reviews, and performance analyses.
