Why we read it this way (5)
The posting requires an active Top Secret clearance as a hard gate, with the additional ability to obtain and maintain TS/SCI — the clearance requirement is set to TopSecret (the active TS is the stated hard gate; TS/SCI is framed as an obtainable upgrade, not a current requirement).
The 2–5 year experience range maps to a Mid-level role; the title 'Software Engineer' carries no explicit seniority modifier, so the title states no level.
Several preferred skills — data pipelines, network traffic analysis, graph data, RF signals, embedded software, OS internals, and microcontroller environments — are listed under 'Nice to have' but name no specific, canonical tool or framework, so they are omitted per the generic-concept rule. Machine learning frameworks are mentioned in the same section and are captured as preferred.
AWS is listed under 'Nice to have' with 'or similar' language; Azure and GCP are listed as alternatives. Docker is also listed under 'Nice to have' and is captured as preferred.
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.
