Overview
We are seeking a Senior Computational Modeling & Simulation Engineer to support the Defense Threat Reduction Agency (DTRA) in advanced Counter-Weapons of Mass Destruction (C-WMD) research and analysis. This role supports high-fidelity computational modeling, simulation, and data analysis related to weapons effects, structural response, blast dynamics, and post-defeat assessments using HPC environments.
The position supports government-sponsored R&D programs focused on Chemical, Biological, Radiological, Nuclear, and High Explosive (CBRNE) threats.
Key Responsibilities
Computational Modeling & Simulation
Perform high-fidelity computational analyses using:
Computational Fluid Dynamics (CFD)
Computational Structural Dynamics (CSD)
Computational Thermal Dynamics (CTD)
Coupled CFD-CSD / CFD-CSD-CTD models
Model weapon effects phenomenology, including:
Blast, fragmentation, cratering, breaching
Ground shock and structural response (above and below ground)
Dust, debris, and agent transport
Secondary detonation effects
Conduct end-to-end weapon-target interaction modeling for WMD storage, transport, and defeat scenarios.
Advanced Analytics & HPC
Leverage DoD High Performance Computing (HPC) systems for large-scale simulations.
Optimize, port, and modernize high-fidelity modeling tools to new HPC architectures (CPU/GPU, distributed memory).
Support fast-running model (FRM) development and integration into decision support tools.
Apply machine learning (ML) techniques for:
Uncertainty Quantification (UQ)
Parameter studies
Reduced-order model development
Verification, Validation & Documentation
Conduct Verification & Validation (V&V) activities and support model accreditation.
Produce:
Technical reports
Validation and verification documentation
Scientific journal articles and conference presentations (subject to DTRA review and release)
Support diagnostics development, field test planning, and post-test data analysis.
Program Support
Participate in government meetings, test planning reviews, and technical briefings.
Support forensic assessments of terrorist or explosive events when required.
Collaborate closely with DTRA-designated technical teams and government stakeholders.
Education
Master’s or PhD in one of the following fields (PhD strongly preferred):
Mechanical Engineering
Aerospace Engineering
Nuclear Engineering
Chemical Engineering
Applied Physics
Computational Science or a closely related discipline
Technical Experience
Demonstrated experience with high-fidelity physics-based modeling
Strong background in one or more of the following:
CFD / CSD / CTD
Finite Element Methods (FEM)
Shock physics
Structural dynamics
Multiphase flow and combustion modeling
Experience working in HPC environments
Proficiency in scientific programming (e.g., C++, Fortran, Python)
Experience with uncertainty quantification (UQ) and parameter studies
Security Requirements
Active DoD Secret Clearance
Location & Work Environment
Primary Location: Contractor facility
Additional Locations: Occasional meetings at government and commercial facilities
Remote/Hybrid: May be permitted depending on tasking and clearance requirements
Travel Requirements
Occasional travel required
Preferred Qualifications (Nice to Have)
Experience supporting DTRA, DoD labs, or national security programs
Familiarity with WMD defeat concepts, BDA, or vulnerability assessments
Experience integrating models into Decision Support Tools (DSTs)
Prior work supporting classified modeling programs
Employment Type
Full-time
W-2 or 1099
