Why we read it this way (8)
The posting does not specify a work location city or CBSA — JT4 supports western US test ranges (e.g. Edwards AFB, China Lake, Nellis), but no specific site is named in this posting.
Experience requirement is tiered by degree: 14 years with a Bachelor's, 10 years with a Master's, or 8 years with a PhD. The 14-year floor (Bachelor's path) is used as the overall years minimum per the minimum-degree rule.
The clearance requirement states candidates 'must be able to obtain and maintain' a security clearance; the specific level is not named. Given the U.S. Air Force/Space Force/Navy federal contract context and the nature of the work, a Secret clearance is the most reasonable inference, though TS may be required — this is flagged as an ambiguity.
Programming languages (Python, C#, C++, Linux, Java) and network architectures (TCP/IP, UDP) are listed in the main job duties description with 'deep understanding' and 'extensive experience' framing, which constitutes firm gating language; they are marked required accordingly.
Telemetry standards (IRIG 106), Open MCT, aircraft/ground instrumentation, real-time data processing, and cybersecurity are described under 'Familiarity with' — a softer qualifier — and are marked preferred.
'Cloud platforms' and 'AI' appear alongside the firmly-gated languages/network skills in the same 'deep understanding'/'strong knowledge' clause and are marked required, though no specific cloud vendor or AI framework is named.
The internal job classification referenced is 'Computer Scientist V,' which aligns with the senior/principal individual-contributor level, but the scope described (single enterprise technical lead, not org-wide authority) supports Senior rather than Staff/Principal.
Requires a 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.
