• Assist in version control and configuration management activities for all SE artifacts—including requirements, the CCE Development Guide, and related documentation—to keep them current with design and development updates.
• Serve as a liaison to subsystem stakeholders, proactively soliciting feedback, addressing inquiries, and incorporating stakeholder input into the SE artifacts.
• Partner with the PaaS development team during integration activities, translating observed issues and design decisions into updated SE documentation.
• Conduct systems engineering analyses—estimating node storage, CCE resource needs, and performance/reliability—to forecast the CCE’s composition and capacity and inform design decisions.
• Support the PaaS development team’s effort to embed Model‑Based Systems Engineering (MBSE) into their routine workflow.
• Partner with the SE&I Execution team to manage baseline updates, ensuring that changes related to baseline deliverables and documentation are accurately incorporated.
• Collaborate with the test automation team to define verification methods for requirements, contribute to review cycles, and ensure that validation activities align with the evolving baseline.
