• Support certification activities and regulatory compliance evidence

• Define and enforce SE process standards and best practices

• Lead technical reviews including SRR, PDR, CDR, and TRR

• Ensure cross-ART architectural consistency by establishing shared systems engineering standards and interface governance

• Lead modernization planning from a systems engineering perspective including decomposition strategies and transition sequencing

• Govern interfaces between legacy and modernized services maintaining technical coherence across the program

• Champion an AI-first engineering culture by identifying and applying AI-assisted development capabilities, automation, and emerging software engineering practices that improve developer productivity, code quality, testing, and delivery.

Core Technical Qualifications:

• Bachelor's degree with 12+ years of relevant experience or Master's degree and 10+ years of experience or equivalent experience.
