Job DescriptionOUSW (R&E) is seeking a highly skilled senior software systems engineer to be the technical lead for a complex project involving the design, development, integration and assessment of complex System of Systems (SoS) architectures for multi-domain autonomous uncrewed platforms (air, surface, and subsurface) in tactical operations over contested radio networks.
This role combines software architecture and systems engineering expertise to prototype advanced, multi-domain autonomy, AI-enabled command and control, and distributed system-of-systems operations. The ideal candidate is a trusted advisor and technical expert with experience guiding model-based systems engineering activities, SoS integration, and test activities across virtual, hardware-in-the-loop (HIL), and live experimentation venues.
Key Responsibilities
- Lead the development, implementation and evolution of MOSA-aligned SoS architecture to integrate uncrewed platforms across multiple domains.
- Lead the software integration of advanced autonomy capabilities for mission orchestration, multi-vehicle coordination, and human-supervised command and control of Agentic-AI based solutions from multiple industry partners.
- Lead the engineering of resilient command, control, and data exchange mechanisms over tactical radio networks (e.g., MANET, Link-16, SATCOM) to ensure operations in degraded, disconnected, or contested environments.
- Coordinate technical integration across software products from multiple industry partners into vehicle platforms and payloads from other industry partners.
- Coordinate System Eng & Architecture activities with M&S and test activities on a continuous basis to ensure alignment throughout execution.
- Serve as a key interface for government stakeholders, industry partners, and technical teams, aligning objectives with OUSW(R&E), Service stakeholders, and transition partners.
- Provide technical guidance for digital engineering, mission simulation, and test planning activities.
- Bachelor's or Master's degree in Computer Science, Systems Engineering, Software Engineering, or a related technical discipline.
- 10+ years of proven experience in software architecture, systems engineering, and integration within the defense aerospace or maritime sectors.
- Deep working knowledge of unmanned and autonomous systems, cross-domain platform integration, and complex System of Systems (SoS) engineering.
- Strong understanding of RF communications, tactical data links, mesh networking, and secure communications protocols suitable for defense applications.
- Cognizant of state of the technology in Agentic AI and multi-agent systems for autonomy capabilities.
- Experience leading and collaborating with cross-functional teams, including interactions with the Joint Staff, Combatant Commands, Military Services, or OSD organizations.
- Proven ability to communicate complex technical findings to senior leadership, technical experts, and non-technical stakeholders.
- Active Top Secret clearance (TS/SCI preferred).
Work Environment
- Working conditions are normal for an office environment.
- Fast paced, deadline-oriented environment.
- May require periods of non-traditional working hours including consecutive nights or weekends (if applicable).
