Advertised as Principal, but the requirements read as Senior.
We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (7)
The job description is extremely sparse on concrete technical requirements — no specific tools, platforms, frameworks, or technologies are named beyond high-level concepts (cybersecurity engineering, risk management frameworks, secure SDLC). The three skills extracted are the only named capability areas mentioned.
Even those three 'skills' are domain concepts rather than named tools; they are retained because the JD explicitly calls them out as requirements, but no specific technology names (e.g., NIST RMF, DISA STIGs, Splunk, etc.) are mentioned.
Work location is not stated anywhere in the posting. The CBSA and state fields are left blank. Remote status is set to false by default given the absence of any remote language, but this is uncertain.
No security clearance is explicitly required, though the employer (Amentum) is a defense/government contractor and clearance may be an unstated expectation. The JD does not gate on one.
The title says 'Principal' but the JD provides insufficient scope detail to confirm org-wide technical authority; the actual seniority is assessed as Senior given the ambiguity and the tiebreaker rule.
No total years of experience requirement is stated in the posting.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): cybersecurity engineering.
