Position: SME - Military Planning & Analysis (Operational Focus) with Security Clearance
R
- Description Leidos’ Homeland Security Sector has an immediate opportunity for a Subject Matter Expert (SME) in Military Planning and Analysis to help shape and deliver next-generation mission planning capabilities supporting nuclear and strategic operations within the defense community. We are seeking a candidate with deep operational mission expertise who can translate real-world mission needs into clear, actionable requirements for software development teams.

You will serve as the critical bridge between mission users and engineers—ensuring development efforts are aligned to operational realities and delivering capabilities that directly enhance mission execution. You will join a highly focused, diverse team of systems engineers, defense program managers, software developers, and test engineers. This job represents a rare opportunity to re-shape and develop new capabilities to improve military planning operations and requires someone who is innovative and self-motivated.

In addition to your mission advisory responsibilities, you will serve in a Systems Engineer / Product Manager capacity—guiding requirements definition, validation, testing, user training, and fielding efforts. This role is not a software coding position; rather, it is centered on operational insight, capability integration, and product leadership. Leidos leverages modern agile and enterprise product methodologies and offers meaningful work-life balance with flexible scheduling.

This is a rare opportunity to directly influence how military planning operations are enabled by software, while remaining grounded in operational reality. Primary work locations:
San Diego, CA or Mons, Belgium.
Remote work is supported; however, the selected candidate must be comfortable spending extended periods onsite as mission needs require. Relocation assistance will be discussed with the selected candidate, as applicable.

Primary Responsibilities:

Operational Leadership
* Serve as the operational authority for military and nuclear mission planning, ensuring software solutions accurately reflect real-world mission planning, execution, assessment, and reporting.
* Act as the primary liaison to end users, capturing and validating operational requirements across Joint, Interagency, Intergovernmental, and Multinational (JIIM) defense environments.
* Provide subject matter expertise across targeting, delivery planning, consequence assessment, survivability, and command-level reporting. Requirements & Product Management
* Translate operational needs into clear, testable requirements, mission threads, and use cases.
* Maintain and prioritize product backlogs in alignment with mission priorities.
* Define acceptance criteria, support sprint and release planning, and ensure end-to-end requirements traceability.
* Develop and manage SOWs, CDRLs, and technical requirements documentation.
* Support user training, deployment, and incorporation of operational feedback into future releases. Systems Engineering & Program Support
* Contribute to system and interface requirements, validating assumptions and evaluating alternatives.
* Review technical artifacts and test results to ensure operational suitability.
* Participate in Agile ceremonies, program reviews, and status reporting to leadership.
* Collaborate with developers and testers to preserve operational intent throughout development.
* Analyze program metrics and recommend improvements to mission effectiveness. Travel
* Up to 15% annual travel in support of user engagement, training, deployment, and requirements activities.

Basic Qualifications:

* Bachelor’s degree in Operations Research, Systems Engineering, Data Science, Computer Science, Statistics, Applied Mathematics, Industrial Engineering, Economics, or a related STEM field.
* 8+ years of experience applying operations research, systems analysis, data analytics, or modeling and simulation in complex operational or defense environments.
* Demonstrated expertise in quantitative analysis, including statistical modeling, optimization, forecasting, simulation, and decision analysis.
* Experience translating analytical results into actionable…
