Provide manufacturing and test engineering support to Production during build, integration, and verification phases
Perform and lead mechanism-level and subsystem-level tests; develop testing requirements, materials, processes, and tooling (vibration, shock, TVAC, assembly)
Participate in and execute design, analysis, and system trade studies to determine mechanism AIT strategies at system and spacecraft levels
Provide inputs to Design Engineering to optimize manufacturing flow, cost, and layout
Prepare detailed product and process reports by collecting, analyzing, and summarizing data
Execute design and analysis using sound engineering principles while adhering to company standards and program requirements
Troubleshoot and investigate anomalies and failures, perform root-cause analysis, and drive resolution
Participate in iterative mechanism design improvements based on findings in test and production

Qualifications
