Description

***Must have an active DOE Q clearance. Active, meaning the individual granted a clearance is briefed and currently occupies a position for which the clearance is required.***

Leidos is seeking a Senior Project Engineer to support the National Nuclear Security Administration (NNSA), Office of Defense Programs. This position supports the Federal Program Managers responsible for nuclear weapons production integration, stockpile sustainment, and modernization programs across the Nuclear Security Enterprise.

The selected candidate will apply advanced engineering and analytical expertise to support one or more mission areas, including:

• NA-125 – Office of Stockpile Modernization (development, integration, and transition to production)

This role operates with limited oversight and requires the ability to evaluate program performance, identify risks, and develop actionable recommendations across complex, multi-organizational programs.

The role requires the ability to synthesize complex technical data across laboratories, production agencies, and DoD stakeholders, translating execution status, risks, and dependencies into decision-quality insights for Federal leadership. You will engage regularly with NNSA headquarters staff, site offices, national laboratories, production agencies, systems engineering teams, and DoD stakeholders to support program coordination, reporting, and execution alignment.

Primary Responsibilities:

• Provide Federal Program Managers with engineering analysis supporting program execution, integration, and delivery across production, sustainment, and modernization portfolios.
• Evaluate technical progress, production readiness, lifecycle performance, and integration risks across programs.
• Monitor and assess execution of program milestones, deliverables, and schedules across laboratories and production agencies.
• Track Defense Programs, DoD, and Congressional actions impacting program priorities and execution.
• Lead responses to data calls, scenario analyses, and leadership inquiries related to program status and risks.
• Coordinate across NNSA headquarters, national laboratories, production agencies, systems engineering teams, and DoD stakeholders to resolve program challenges.
• Develop executive-level briefings, reports, and issue papers outlining technical progress, risks, and mission impact.
• Oversee tracking of action items and deliverables to ensure alignment with program objectives and schedules.
• Evaluate performance trends and recommend mitigation strategies to address production, sustainment, and modernization risks.
• 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 program reviews.

Requirements:

• Active DOE Q clearance.
• Bachelor’s degree in Engineering or related STEM field with 12+ years of experience or Master’s degree with 10+ 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 and manage competing priorities in a high-visibility environment.
• Proficiency in Microsoft Office Suite (Word, Excel, PowerPoint) and Microsoft Teams.
• Strong written and verbal communication skills, including experience preparing materials for leadership review.
