Job Summary

Leidos is seeking a highly skilled Modeling Engineer to support critical national security missions for the Defense Threat Reduction Agency and the Defense Intelligence Agency. This position focuses on advanced structural modeling of complex facilities critical infrastructure and target environments to enable Countering Weapons of Mass Destruction and Hard and Deeply Buried Target vulnerability and defeat assessments.

The ideal candidate will bridge the gap between field-captured spatial data and high-fidelity analytical this role you will lead 3D Building Information Modeling efforts manage cross-domain data movement between unclassified and classified networks and perform field surveys using LiDAR and point cloud technologies.

Key Responsibilities

Structural and Infrastructure Modeling

  • Build detailed high-fidelity 3D BIM models of complex underground hardened and above-ground facilities including structural framing foundations and critical utilities.

  • Map complex system-of-systems connectivity including structural dependencies HVAC/MEP systems communications power and operational equipment.

  • Convert technical operational and intelligence data into precise spatial models to support blast impact structural integrity and physical vulnerability simulations.

Reality Capture and Field Surveying

  • Execute field data collection using terrestrial aerial and mobile LiDAR systems handheld scanners and photogrammetry tools.

  • Process clean stitch and georeference large point cloud datasets into actionable BIM environments using scan-to-BIM workflows.

  • Participate in CONUS and OCONUS site surveys in dynamic environments to capture ground-truth physical characteristics.

Cross-Domain Data Handling and Architecture

  • Manage model development across multiple classification levels including Unclassified Secret and TS/SCI environments.

  • Prepare filter and validate spatial and geometric data for high-to-low and low-to-high cross-domain transfer protocols.

  • Maintain strict model security controls ensuring attribution and metadata conform to Intelligence Community classification guidelines.

Mission Support and Threat Assessment

  • Collaborate with weapon effects analysts structural dynamicists and intelligence specialists to support target vulnerability and defeat assessment pipelines.

  • Quantify structural load paths material properties and failure modes under extreme loading conditions.

  • Serve as a subject matter expert within the technical domain area.

  • Deliver technical briefs spatial analytical products and interactive 3D visualizations to key Department of Defense decision-makers.

Required Qualifications

  • U.S. citizenship is required.

  • Candidate must possess an active TS/SCI clearance or a Top Secret clearance with a current SSBI and be eligible to obtain a TS/SCI with polygraph.

  • In-depth understanding of technical principles theories concepts and their application across a range of programs.

  • Typically requires a bachelors degree in civil engineering structural engineering mechanical engineering geographic information systems or a related STEM field and 1215 years of relevant prior experience. A masters degree is preferred.

  • Relevant work experience includes structural or systems modeling BIM workflows and facility spatial analysis.

  • Additional relevant experience may be considered in lieu of a degree.

  • Proficiency with Autodesk Revit Navisworks AutoCAD SolidWorks Bentley Systems including OpenBuildings or MicroStation or other applicable modeling software.

  • Hands-on experience with point cloud processing software such as Autodesk ReCap Leica Cyclone FARO Scene or CloudCompare.

  • Direct experience conducting LiDAR scanning and photogrammetric site collections.

Preferred Qualifications

  • Prior experience supporting DTRA DIA U.S. Strategic Command or U.S. Special Operations Command counter-threat missions.

  • Familiarity with Hard and Deeply Buried Target design concepts underground engineering or hardened structures.

  • Background with cross-domain transfer platforms including CDS tools guard solutions and data sanitization standard operating procedures.

  • Understanding of finite element analysis or computational fluid dynamics modeling integration such as Ansys or LS-DYNA.

  • Knowledge of GIS platforms including ArcGIS Pro and CAD-to-GIS integration workflows.
