Senior System Engineer

The role blends system administration, infrastructure engineering, and cybersecurity (FISMA/NIST compliance, identity management), making it a genuine hybrid between 15-1244 (Systems Administrators) and 15-1212 (Information Security Analysts). 15-1244 was chosen as primary because day-to-day responsibilities center on operating, maintaining, and engineering infrastructure rather than security analysis per se.

Degree requirement is marked None: the JD explicitly states that additional professional experience and IT certifications may be substituted for a Bachelor's degree, and that an Associate's degree plus 4 years of experience can equate to a Bachelor's degree — equivalent experience is accepted.

The long list of technologies under 'Significant experience in one or more of the following areas' is framed as a pick-list (depth in at least one area), not a gate on every item. All items in that list are marked preferred accordingly.

The 10+ years figure is the stated overall experience floor; the 5+ years of highly-available infrastructure experience is a secondary role-level requirement captured in the overall years minimum at the higher 10-year figure.

No compensation range is provided in the posting.

U.S. Citizenship is required but is not a technology skill; it is captured via the Top Secret clearance gate (which implies citizenship).

Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): DoD 8570 IAT Level II.

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.
