Modeling, Simulation & Training Software Engineer

2 days ago Be among the first 25 applicants

We’re seeking a hands‑on Software Engineer with deep experience in the Modeling, Simulation, and Training (MS&T) industry to build and integrate high‑fidelity training solutions for Defense customers—especially Army and Navy programs. You’ll develop C++ software that interoperates across distributed simulation environments and connects to simulators used for operator training, mission rehearsal, and systems test.

• Deliver dependable, high‑fidelity training capabilities that improve warfighter readiness
• Advance interoperability across Live/Virtual/Constructive (LVC) training systems
• Reduce integration risk by adhering to standards (HLA/DIS) and VV&A practices

• Design & implement production‑grade C++ subsystems for real time simulation, training devices, and constructive forces.
• Integrate distributed simulations using HLA (High Level Architecture) and DIS (Distributed Interactive Simulation), including federation object model (FOM) work, RTI integration, and entity/state synchronization.
• Develop and maintain simulators (desktop and full mission) for Defense programs; collaborate with Army/Navy stakeholders, integrators, and test teams.
• Model behaviors and systems (platforms, sensors, weapons, comms) and validate against authoritative data and requirements.
• Profile & optimize for determinism and low‑latency networking; troubleshoot timing/jitter and packet‑level issues.
• Automate build/test (CI/CD) and contribute to configuration management, requirements traceability, and accreditation artifacts.
• Author engineering documentation (designs, ICDs, test plans, user guides) aligned to defense program standards.

• ONESAF (One Semi Automated Forces) integration, scenario development, or model customization experience (huge plus).
• Familiarity with Army training programs (e.g., CCTT/FSTSS) and Navy surface/undersea training ecosystems.
• Experience with RTI‑specific tooling, RPR FOM, and interoperability testing across mixed HLA/DIS environments.
• VV&A, requirements traceability, and defense program documentation.
• Experience with physics modeling, sensor phenomenology, terrain/IG integration (e.g., OGC CDB, Open Flight), or game engines (Unity/Unreal) for trainer UIs.
• Dev Ops/Automation: CMake, Conan/vcpkg, Git, Jenkins/Git Lab CI; containerization (Docker) for build/test.
• Real time OS tuning (thread priorities, CPU affinity) and performance profiling on Windows/Linux.
• Active DoD Secret clearance.
