What this job asks for AI summary

A defense-contractor data scientist role focused on designing, building, and deploying AI/ML solutions — including autonomous agents, LLM-based systems, and reinforcement learning — against large-scale datasets in support of national security missions. The position requires hands-on development in Python with modern ML frameworks and spans the full lifecycle from model development and optimization through deployment. Candidates must already hold an active TS/SCI with polygraph.

Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Aug 18, 2026. It is a model, not a headcount.

Why we read it this way (6)

The title 'Data Scientist Level 3' maps to a mid-level numeric designation, but the experience requirements (8+ years with a bachelor's, 6+ with a master's, etc.) and the breadth of responsibilities clearly support a Senior-level classification.

No work location is specified in the posting. Given the TS/SCI + polygraph requirement and national security mission context, this is almost certainly an on-site role, but the specific site or metro area is not stated.

The degree requirement accepts multiple pathways including a high school diploma with 12 years of experience, so no minimum formal degree is hard-gated — equivalent experience is explicitly accepted.

PyTorch and TensorFlow are listed as alternatives within the same 'such as' clause; LangChain is listed alongside them but is a distinct tool (orchestration framework vs. training library), so it is captured separately.

The TS/SCI polygraph clearance is an explicit hard gate: candidates must already possess an active clearance to be considered.

Requires a TS/SCI 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.
