• Track Defense Programs, DoD, and Congressional actions impacting program priorities and execution.
• Respond to short-notice data calls, scenario analyses, and leadership inquiries related to program status and risks.
• Coordinate communication across NNSA headquarters, national laboratories, production agencies, and DoD stakeholders to resolve program challenges.
• Develop program plans, executive briefings, reports, and issue papers outlining technical progress, risks, and mission impact.
• Track and facilitate action items and deliverables to ensure timely execution of program activities.
• Evaluate performance relative to technical objectives, schedule milestones, and quality requirements, and provide recommendations to Federal leadership.
• Support DOE product realization processes, program reviews, and interagency coordination activities across assigned mission areas.
• Support recurring reporting requirements, including portfolio assessments and senior-level reviews.

Requirements:

• Active DOE Q clearance.

• 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.
