Structural Engineer - TS/SCI Poly Required

Leidos is seeking an experienced Structural Engineer to support a critical national security mission focused on the characterization, analysis, and assessment of hardened, underground, and protective facilities. This role offers the opportunity to apply advanced engineering expertise to some of the most challenging and complex problems in the defense and intelligence community. As a key member of a multidisciplinary team, you will combine structural engineering knowledge, intelligence analysis, geospatial data, and innovative problem-solving techniques to evaluate facilities, infrastructure, and protective systems worldwide. Your work will directly contribute to high-priority mission objectives and inform senior-level decision-making. The ideal candidate is a technically strong engineer who thrives in ambiguity, enjoys solving complex problems with incomplete information, and possesses exceptional attention to detail, analytical rigor, and intellectual curiosity.

Conduct advanced structural engineering analysis, research, and modeling of buildings, underground facilities, and protective structures. Evaluate structural performance related to blast resistance, penetration resistance, damage tolerance, durability, dynamic loading, stability, fatigue, and overall structural capacity. Integrate all-source intelligence, geotechnical information, topographical data, and engineering expertise to characterize facility missions, layouts, construction methods, and vulnerabilities. Develop comprehensive facility assessments, including mission systems, support infrastructure, physical configurations, and detailed 3D models. Apply engineering judgment and technical leadership throughout the characterization process to produce accurate, defensible intelligence assessments. Develop innovative solutions to highly complex technical challenges through research, modeling, and application of engineering best practices. Provide technical guidance and subject matter expertise to multidisciplinary teams. Brief senior government leaders and decision-makers on engineering findings, trends, risks, and mission impacts. Collaborate closely with government and contractor personnel in a fast-paced, mission-focused environment.
