Senior Modeling & Simulation Engineer

Intuitive Research and Technology Corporation•Orlando, FL

About The Position

INTUITIVE® is a nationally recognized Best Place to Work that provides solutions from design through production to sustainment by delivering targeted results. Our approach couples the latest technology with engineering expertise and analytical proficiency while remaining true to genuine customer relationships and a culture that fosters growth and opportunity. Our diverse portfolio of capabilities and extensive customer base allows our employees countless opportunities to pursue their passions and support our nation’s Warfighters. Join our team that encourages creativity, welcomes initiative, and seeks excellence. Start Building Your Future today! We are seeking a Senior Modeling & Simulation (M&S) Engineer who combines depth in high-fidelity physics modeling with breadth across the modern M&S ecosystem. In this role you will 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, and drive performance, reliability, and validation from prototype through production. You will contribute to verification, validation, and accreditation (VV&A) activities that establish credibility and intended-use accreditation, collaborate with cross-functional teams, and build robust tooling (automation, Monte-Carlo, design-of-experiments) to analyze outcomes and support decisions. Experience using mission/entity-level environments (e.g., AFSIM, OneSAF, STK) and pairing them with modern visualization pipelines (Unity/Unreal via DIS/HLA bridges) is highly valued. Ultimately, you translate models into maintainable, supportable capabilities and help the organization evolve toward commercially licensable product offerings.

Requirements

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

Nice To Haves

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.
