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.
Author and maintain requirements in accordance with INCOSE requirements writing guidance, ensuring "shall" statement quality, traceability, and verification method assignment.
Coordinate across functional groups (Systems Engineering, Software Engineering, InfraSecOps, Data Conditioning, Visualization) to negotiate interface and design solutions.
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.
Maintain strong attention to detail and organizational discipline across concurrent documentation, board, and model-maintenance activities.
