Lead the design and integration of MOSA-aligned System of Systems architectures for multi-domain autonomous platforms. Coordinate technical integration of AI-enabled command and control solutions across multiple industry partners and government stakeholders.
Requires a Bachelor's or Master's degree in a technical field and over 10 years of experience in software architecture and systems engineering within defense sectors. An active Top Secret clearance is mandatory.
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.

Challenge Accepted
Founded in 1989 and headquartered in Reston, Virginia, SOSi is a private, founder-led defense and government solutions firm specializing in advanced technology systems and mission support. Our capabilities span data science, software development, network engineering, intelligence, surveillance and reconnaissance (ISR), language services, and logistics—delivered across 16+ countries to the customers who need them most. We lead with technology. From the DoW's largest data-centric, Zero Trust mission partner network to AI-powered intelligence platforms and cloud-native solutions, SOSi engineers the systems that enable U.S. and allied forces to operate, decide, and win. More than 25% of our workforce are veterans—because this mission is personal. Where others see the size of the challenge, we say #ChallengeAccepted -- Fraud Alert: Recruitment fraud is a growing trend where fraudsters impersonate SOSi and its employees to deceive job seekers with fake employment opportunities. These scams typically involve fake job postings, unauthorized email accounts, or forged documents claiming to be from SOSi. The intent is to gain access to your personal information, including banking details, credit card numbers, or social security numbers. Please be aware that all legitimate SOSi communications come from official @sosi.com or @sosi.us email addresses, and we never request personal information during initial contact. Our official careers site can be found at sosi.com/careers and our corporate site at sosi.com. If you receive a suspicious job offer claiming to be from SOSi, contact us directly at [email protected] to verify its legitimacy.
