Customer Success Engineer, Battle Road [Ft. Leavenworth]

About the role

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination. The Customer Success Engineer at Battle Road operates at the intersection of engineering and mission execution within high-stakes defense environments. You will deploy AtomEngine into real-world military training environments, including Secret and air-gapped systems, where you will configure, extend, troubleshoot, and improve the platform while working directly with customers. You may be supporting live exercises, adapting simulations, or ensuring the software performs under pressure alongside warfighters in the field. You are the last mile between Battle Road's simulation technology and the warfighter, ensuring the technology enables decisive action rather than obstructing it. This role demands a rare blend of technical depth, operational empathy, and resilience in demanding conditions where reliability is non-negotiable. You will translate complex military workflows into robust software behaviors while ensuring that every deployment aligns with the strategic objectives of the mission.
