Software Engineer — Modeling, Simulation & Training (MS&T)

Description

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.

Impact

• 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

What You’ll Do

• 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.

Skills & Qualifications

• Expert C (modern C 17/20) with STL/Boost and multithreading; strong debugging and performance tuning skills.
• HLA (Evolved) experience, including FOM/SOM design and integration with a commercial RTI (e.g., Pitch, VT MAK).
• DIS experience (entity/weapon/sensor PDUs; exercise management; dead reckoning).
• Proven MS&T industry experience (simulation/training systems used in defense contexts).
• Hands on with networked real time systems on Windows and/or Linux; UDP/TCP/IP multicast; Wireshark or equivalent tooling.
• Bachelor’s in Computer Science, Computer Engineering, or related field (or equivalent practical experience).
