• Ensure system-of-systems integration across FAA environments
• Support verification and test planning for requirements and interfaces
• Participate in major lifecycle reviews (SRR, PDR, CDR, TRR, etc.)

Performance, Risk & Technical Stewardship

• Plan and execute analyses and modeling to assess performance, availability, reliability, and operational suitability
• Identify architectural risks, tradeoffs, and mitigation strategies
• Identify required subject matter expertise, tools, and techniques to meet technical objectives
• Act as the technical conscience of the program, ensuring solution quality is not compromised

Technology Roadmap, Modernization & Future Solutioning

• Develop and maintain a forward-looking technology roadmap aligned with FAA strategic objectives
• Evaluate emerging technologies and define transition strategies for modernization
• Conceptually shape future system enhancements and capability expansions
• Support technical solution development for follow-on efforts, contract modifications, and growth opportunities
• Collaborate with business development and capture teams to ensure architectural continuity between current program execution and future solutions
• Ensure proposed enhancements align with the established architecture baseline and long-term system vision

Engineering Innovation & AI-Enabled Transformation

• Define and execute a strategic roadmap for AI-enabled engineering transformation within the program
• Lead responsible integration of Generative AI into systems engineering and software development activities

Implement AI-assisted capabilities for:

• Requirements analysis and traceability
• Model-based systems engineering (MBSE) artifacts
• Code generation and review
• Automated test development
• Compliance and documentation automation
• Establish governance and guardrails to ensure AI adoption aligns with FAA policies, federal AI directives, and Zero Trust principles
• Ensure innovation enhances quality, compliance, and mission effectiveness in a regulated environment

Stakeholder Engagement

• Work closely with FAA stakeholders, engineers, managers, and users to ensure risks, issues, and solutions are clearly communicated
• Partner with the Program Manager and Chief Engineer to align technical execution with customer vision
• Serve as the senior technical interface for architectural matters

Required Qualifications

• Bachelor’s degree with 10+ years of relevant experience
• 8+ Years of Specialized experience – includes: supervision of system architects, use of structured analysis, design methodologies and design tools, and other design techniques, object- oriented principles, and experience with the logical and physical functional, operation, and technical architecture of large and complex information systems

• Distributed architectures
• Containerized environments (Docker, Kubernetes)
• High-availability systems
• Excellent written and verbal communication skills

Preferred Qualifications

• Prior experience serving as System Architect, Software Architect, or Product Architect on an FAA program
• Experience supporting technical solutioning for follow-on contracts or program growth
• Experience modernizing legacy systems to cloud-native architectures
• Experience implementing AI-enabled engineering practices in regulated federal environments
• Familiarity with cost estimation
