Why we read it this way (9)
The job location is not explicitly stated in the posting. Lockheed Martin's EBDT organization operates across multiple facilities; no specific city or CBSA could be determined from the text.
The role title is 'System Engineer' but the day-to-day responsibilities — patching, vulnerability scanning, asset inventory, OS administration, infrastructure support, and STIG/RMF compliance — are squarely infrastructure operations (15-1244). The security compliance and hardening duties create a genuine pull toward 15-1212, but the primary work is running and maintaining classified infrastructure rather than analyzing threats or conducting security assessments.
The clearance requirement is stated as TS/SCI with a CI Polygraph — both in the Basic Qualifications and the Clearance Level field.
The 3-year figure comes from the Desired Skills section ('3+ years administering and supporting enterprise-class, classified IT infrastructure'). No overall experience floor is stated in Basic Qualifications, so this is the best available proxy for the overall years minimum.
JIRA and Confluence appear in the Responsibilities section (not a formal 'Required' block), but the language is operational and directive ('Update Service Central tickets, JIRA issues, and Confluence pages'), making them functional requirements for the role.
The MATLAB/Simulink, SysML/UML, and MBSE tools (Rhapsody, Cameo, PTC Integrity) appear under Desired Skills and are unusual for a classified IT infrastructure role — they may reflect the broader engineering environment at Lockheed Martin rather than core duties of this position.
No compensation figures are provided in the posting.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Aria Operations.
Requires a TS/SCI 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.
