Job description

Customer & Solutions · Fort Belvoir, VA · FullTime · Mid level

This role puts an engineer directly inside military training settings to set up, adjust and keep a simulation platform running, often on classified or offline systems. A strong candidate combines hands on coding in languages like C++, C# or Python with the ability to troubleshoot networks and integrations under time pressure. Clear communication with military users and the confidence to fix problems live in front of a crowd matter as much as technical depth.

How it fits the AI era

The product brings planning, simulation and AI into one environment, so this role sits where that tooling meets real exercises. Much of the setup, scripting and integration work still needs a person who understands the operational context and can adapt quickly when conditions change. Judgement about what the customer actually needs, and explaining it plainly, stays human.

How it builds AI experience

Working here means gaining hands on exposure to AI assisted planning and simulation tools used in defense settings, plus practice deploying software in restricted and air gapped environments. Building that experience starts with scripting and engine work in Godot, C++ or Python and learning how simulation entities and behaviors are extended. Familiarity with modeling, simulation or defense systems helps, and presenting technical ideas to groups strengthens the fit.

Worth showing

• C++ or Python coding
• Systems and network troubleshooting
• Military domain familiarity
• Clear technical communication
