Growth Opportunities

No H1B

Security Clearance Required

U.S. Citizen Only

Responsibilities

Design and implement physics-accurate models (e.g., rigid-body dynamics; sensors across RF/EO/IR; guidance, navigation & control; environmental/terrain effects)

Integrate them into distributed simulation networks using standards such as HLA, DIS, and TENA

Drive performance, reliability, and validation from prototype through production

Contribute to verification, validation, and accreditation (VV&A) activities that establish credibility and intended-use accreditation

Collaborate with cross-functional teams

Build robust tooling (automation, Monte-Carlo, design-of-experiments) to analyze outcomes and support decisions

Translate models into maintainable, supportable capabilities

Help the organization evolve toward commercially licensable product offerings

Required

ABET accredited BS degree

Minimum 10 years of related experience

Proven experience building physics-based simulations suitable for real-time or faster-than-real-time execution (numerical methods, sensor/weapon phenomenology, kinematics/dynamics, terrain/environment)

Hands-on interoperability with one or more of: DIS (IEEE 1278), HLA (IEEE 1516 family), or TENA, including FOM/OMT concepts, publish/subscribe data exchange, time management, and semantic alignment across federates

Practical VV&A experience: plan, execute, and document verification/validation; produce accreditation evidence aligned to DoD guidance

Strong software development skills in one or more of: C++ for performance-critical code; Python for analysis/scripting and pipelines; MATLAB/Simulink for controls/plant modeling and C# for engine integration (Unity)

Experience with at least one major M&S environment (e.g., AFSIM for mission-level analysis, OneSAF for entity-level CGF/SAF, STK for digital mission engineering) and the ability to select/extend tools to meet fidelity and analysis needs

Clear written and verbal communication; ability to author technical documentation and present analysis to technical and non-technical stakeholders

Must have an in-scope DoD Secret security clearance

Preferred

Integration of Unity/Unreal visualizations with DIS/HLA bridges (e.g., Open-DIS, coreDS); familiarity with dead-reckoning, coordinate frames, and real-time networking concerns

Experience leading or contributing to federations across LVC enterprises; familiarity with DSEEP practices and standards communities (SISO/IEEE)

Prior involvement in commercial productization (packaging, licensing/activation, documentation, support processes) as an engineer, technical advisor/architect, or product team member

Solid foundation in numerics and statistics (ODE/PDE solvers, Monte-Carlo, sensitivity analysis, uncertainty quantification) and disciplined configuration/data management

Familiarity with export controls (ITAR/EAR) when applicable
