This role requires the ability to integrate complex technical and programmatic data across multiple sites, programs, and organizations, shape program strategy, and influence decision-making at the federal leadership level.

Primary Responsibilities:

• Lead enterprise-level engineering analysis supporting program strategy, integration, and execution across production, sustainment, and modernization portfolios.
• Advise Federal Program Managers on technical maturity, production capacity, lifecycle performance, and integration risk posture.
• Evaluate cross-program dependencies and impacts affecting development, qualification, production, and delivery across the enterprise.
• Assess impacts of technical, programmatic, and policy decisions on program execution and mission delivery.
• Lead responses to complex data calls, scenario analyses, and senior leadership inquiries.
• Drive coordination across NNSA, national laboratories, production agencies, systems engineering teams, and DoD stakeholders to resolve complex program challenges.
• Develop executive-level briefings and decision-support materials for senior federal leadership.
• Identify systemic risks and cross-program impacts and recommend mitigation strategies.
• Oversee portfolio-level performance tracking, trend analysis, and risk identification across assigned mission areas.
• Support high-visibility program reviews, portfolio assessments, and strategic planning activities across Defense Programs.

Requirements:

• Active DOE Q clearance.
• Master’s degree in Engineering or related STEM field with 15+ years of experience or a Doctorate with 13+ years of experience.
• Experience supporting engineering, research, development, production, sustainment, or modernization programs within DOE/NNSA, DoD, national laboratories, or production agencies.
• Demonstrated ability to apply analytical skills to inform technical or programmatic decisions.
• Understanding of Nuclear Security Enterprise roles and responsibilities, including design and production agency interfaces.
• Experience working within federal, defense, national laboratory, or similarly complex technical environments.
• Strong organizational skills with high attention to accuracy and detail.
• Ability to operate independently at a senior level and influence decision-making in a high-visibility environment.
• Proficiency in Microsoft Office Suite (Word, Excel, PowerPoint) and Microsoft Teams.
• Strong written and verbal communication skills, including executive-level engagement.
