Prepare technical packages and represent Systems Engineering at the Engineering Review Board (ERB), Configuration Control Board (CCB), and Discrepancy Review Board (DRB), including change impact analysis and disposition tracking. Support Functional Configuration Audit (FCA) and Physical Configuration Audit (PCA) activities, ensuring documentation and model artifacts align with delivered baselines. Participate in Agile execution within a SAFe Agile Release Train — including PI Planning, backlog refinement, and feature/story-level requirements decomposition — in coordination with the Product Owner and Chief Systems Engineer.

Support development and maintenance of DoD systems engineering artifacts (SEP, SEMP, TEMP, CMP, DMP) as required by the program's contract and governance model. Coordinate with government customers, subcontractors (e.g., SAIC/Koverse, Anduril/SPySE), and other contractor teams in a collaborative, government range environment. Support System Installation and integration efforts, including coordination with procurement and logistics for hardware and software delivery. Possess strong analytical and troubleshooting skills, with the ability to isolate root cause across system, interface, and requirements issues.
