Why we read it this way (8)
The posting is titled 'Multiple Levels' with a salary range of $90K–$220K, indicating it covers a wide band from mid to senior. The seniority is assessed as Mid based on the minimum qualifying path (Bachelor's + 4 years), though the role's leadership expectations (guiding Rust adoption, architectural guidance) lean toward Senior for the upper end of the range.
Degree requirement is set to None because the JD explicitly accepts 8 years of experience in lieu of a degree.
The active DoD Secret clearance is a hard gate stated in the Qualifications section.
Rust experience of 1+ years is explicitly required in the Qualifications section; C/C++ experience is also listed there as a hard gate.
Python and the specific RTOSes (VxWorks, Linux, Integrity) appear in the Essential Functions narrative describing the work environment rather than in a formal requirements gate, so they are marked preferred.
The preferred skills section explicitly covers: C/C++ to Rust conversion experience, embedded Rust, UML/modeling tools, device drivers/BSPs, Information Assurance/cryptography, and DO-178/NSA Type 1 certification.
The role requires >30% travel to other L3Harris locations, which is notable for candidates.
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.
