Responsibilities:

Work with the technical team to establish robust and executable program plans including the identification of tasks, trade studies, modelling, analyses, and risk management

•Review and assess customer requirements, establish requirements management including validation, decomposition, flow down, and technical budgeting

Develop specifications and interface control documents

•Develop and guide verification including a requirements verification matrix, verification plans, test requirements, and preparation of sell-off materials to demonstrate compliance

•Evaluate the work and results from the technical team to provide feedback and direction

•Communicate with the program office, functional management, and technical team members to ensure proper program execution and early issue and risk identification

•Document statement of work (SOW) and performance specifications for subcontracted items
