Why we read it this way (9)

The title 'Sr Principal Software Security Engineer' is advertised at Principal level, but the actual requirements — 10+ years of experience, hands-on embedded development, and component-level scope — are consistent with a Senior engineer. 'Sr Principal' at RTX/Raytheon is an internal grade that maps closer to a Senior IC than to a true org-wide Principal.

The clearance requirement is stated as 'Interim Secret' (ability to obtain before start date), which gates on Secret-level eligibility. Mapped to Secret clearance.

The role is genuinely dual-natured — primarily embedded software development in C/C++ with a strong security focus — making 15-1252 (Software Developers) and 15-1212 (Information Security Analysts) both plausible. Primary day-to-day work (design, develop, integrate, test real-time software) tips toward 15-1252.

Xilinx UltraScale+ MPSoC and Versal are listed as interchangeable options ('or comparable embedded processors'); Versal is captured as an alternative. 'Comparable embedded processors' is an open-ended qualifier but no other specific processor family is named.

VxWorks and Embedded Linux are listed as interchangeable examples of embedded OS experience; emitted as one skill with VxWorks as primary and Embedded Linux as alternative.

Hardware interfaces (PCIe, GPIO, I2C, SATA) and modern hardware technologies appear under a preferred section; PCIe and I2C are emitted as representative named technologies. GPIO and SATA are omitted as they are generic interface types rather than distinct named tools.

No compensation figures are provided; the posting notes only that salary and incentive eligibility depend on level and other factors.

U.S. citizenship is a hard requirement tied to clearance eligibility, not captured as a skill but noted here for recruiter awareness.

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.
