Mentor and train the junior Systems Engineers on the program in key system activities and products (requirements decomposition and derivation; writing and capturing requirements in DOORS/CAMEO; planning verification of each requirement; interaction with other disciplines in understanding if a requirement is achievable or not; capture of interface requirements, etc.) Responsible for the development, decomposition, refinement and documentation of system, subsystem and component requirements and capabilities to support the Sentinel program. This includes ensuring the system architecture is captured in CAMEO and corresponding requirements are captured in DOORS (and that the two are consistent). The Sentinel Staff Systems Engineer is directly responsible for working on the overall System-level development effort including integration of subsystem elements into the overall System-level design architecture and related formal deliverables to the customer The Sentinel Staff Systems Engineer is directly responsible for working the overall System-level end to end performance assessments of the Sentinel system and identifying and leading the resolution of systems performance gaps relative to stakeholder requirements. Lead and collaborate with systems engineers, other disciplines, suppliers, management and the customer to ensure timely development and delivery of the Sentinel deliverables Lead ad-hoc teams in the execution of tasking directed by the SEIT PM and per the Integrated Master Schedule. Assume ownership of different portions of the development effort.
