Summary

HII Mission Technologies is seeking an experienced Senior Software Developer to support the Expeditionary Unmanned Systems (ExUS) portfolio under NIWC Pacific. This role includes a Hybrid schedule (averaging 1–2 days onsite per week). Hybrid participation is ideal for team collaboration and program integration; however, fully remote may be considered depending on experience and location outside the local area.

The Senior Software Developer will design, implement, test, and integrate advanced software components for COIN/Nexus, Common Control System (CCS) modules, and other UUV command-and-control capabilities used across the Navy’s ExUS programs. This role supports mission‑critical unmanned underwater vehicle operations and requires strong C#, Angular, UI development skills, and experience with Navy maritime software environments.

You will collaborate closely with NIWC PAC technical staff, fleet operators, systems engineers, and government stakeholders to ensure system readiness and the successful transition of new capabilities to the field. #LI-MJ1
