Why we read it this way (8)
An active TS/SCI with Full Scope Polygraph is an explicit hard gate — candidates without it cannot be considered.
The role is fully onsite in Herndon, VA; no remote or hybrid option is mentioned.
Compensation is described only as 'highly competitive salary' with no figures given — no range could be extracted.
No overall years-of-experience requirement is stated anywhere in the posting.
The role has a meaningful security-hardening and PKI/firewall component that could push it toward Information Security Analyst (15-1212), but the primary day-to-day work — O&M, server builds, patching, backups, access control — aligns more closely with Systems Administration (15-1244).
'Cloud platforms' is listed as a hard gate based on the core responsibility of managing the Sponsor's cloud R&D environment; the specific cloud provider is not named.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): patch management, system backup and restore.
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.
