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.
