SeniorSoftwareSystemsEngineer

Founded in 1989, SOSi is among the largest private, founder-owned technology and services integrators in the defense and government services industry. We deliver tailored solutions, tested leadership, and trusted results to enable national security missions worldwide. OUSW (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 i
