What this job asks for AI summary
A senior technical lead role focused on designing, integrating, and assessing System of Systems architectures for autonomous uncrewed platforms operating across air, surface, and subsurface domains over contested tactical radio networks. The work centers on prototyping multi-domain autonomy, AI-driven command and control, and resilient data exchange, while coordinating software integration across multiple industry partners and serving as a primary technical interface with government stakeholders. Suits a seasoned defense software/systems engineer with a Top Secret clearance.
Senior level · 10+ years · National · Bachelor's required · Top Secret clearance
“or” means any one of them counts — you don't need all of them.
We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (9)
No work location is specified in the posting; the CBSA/state fields are left blank. The role is tied to OUSW (R&E) defense work and is almost certainly on-site at a government facility, but the city is not stated.
Clearance: the JD hard-gates on an active Top Secret clearance; TS/SCI is listed as 'preferred' rather than required, so the gate is set at TopSecret (not TopSecretSci).
The role blends software architecture, systems engineering, and technical leadership across a System of Systems program. It was classified as Software Developers (15-1252) because the primary day-to-day work is designing and integrating software for autonomous platforms; 15-1299 (Computer Occupations, All Other) is the runner-up given the heavy systems-engineering and cross-domain integration emphasis.
Skills such as 'software architecture', 'systems engineering', and 'SoS integration' are listed here because the JD uses them as explicit, named technical disciplines with firm gating language ('deep working knowledge', 'proven experience') — not merely as generic responsibilities.
MANET, Link-16, and SATCOM are listed as interchangeable examples of tactical radio network technologies in the JD; they are captured as alternatives under a single skill node.
Agentic AI, MBSE, HIL testing, digital engineering, and mission simulation appear in the responsibilities/context sections rather than under a distinct 'required' gate, or are framed as awareness ('cognizant of') rather than proven expertise — treated as preferred accordingly.
No compensation information is provided in the posting.
Ignored 4 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): software architecture, systems engineering, model-based systems engineering (MBSE), digital engineering.
Requires a Top Secret clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
