Why we read it this way (7)
The clearance field is set to None because the JD states the role requires the ability to obtain a DHS Public Trust clearance — not an active clearance — and Public Trust is a suitability determination, not a formal US security clearance level (Confidential/Secret/TS/SCI).
Location is not explicitly stated in the posting; inferred as the Washington DC metro area given the DHS/C3 customer context (DHS Cyber Crimes Center is headquartered in Fairfax, VA).
TensorFlow, PyTorch, and scikit-learn are listed together as a required ML framework group; all three are marked required with each other as alternatives to reflect that the JD treats them as a suite rather than strict pick-one substitutes.
SHAP and LIME are listed together as required explainable AI methods; SHAP is the primary with LIME as an alternative.
Generative AI/LLMs, Elasticsearch, Kibana, graph databases, federal AI policy familiarity, OSINT, and streaming/CDC experience all appear under the 'Desired' section and are marked preferred.
The salary range ($94,400–$198,200/year) is wide and explicitly noted by CACI as subject to geographic and contract-rate factors.
The posting notes this position is contingent on funding and may not be filled immediately.
