Unmanned Surface Vehicle; USV Craft Maintainer​/Operator, Maritime

SMX is seeking four USV Craft Maintainer/Operators to support NSW TF-ABLE by maintaining, sustaining, and operating a dedicated fleet of 6–10 USV training craft located at Stennis Space Center, MS. and Virginia Beach, VA. These training platforms are based on modified Yamaha FX-SVHO/FX-SHO personal watercraft and are used to train future operators and maintainers for global maritime missions.

These positions require technically capable, self‑motivated individuals who can rapidly learn autonomy systems, software workflows, and mission‑planning tools while supporting day‑to‑day platform readiness, operator training, mission rehearsal, remote monitoring, launch/recovery activities, and hands‑on maintenance, troubleshooting, and operational checks of USV training craft in a maritime training environment.

This position requires a DoD Secret security clearance and TS/SCI eligibility which requires US citizenship for work on DoD contracts.

This position is onsite at either Stennis Space Center, Mississippi.
