What this job asks for AI summary
This role centers on administering and modernizing enterprise identity and access management platforms — including Cisco ISE, Aruba ClearPass, RSA SecurID, and LDAP — within a government IT environment. Day-to-day work involves automating routine operations using Python and Ansible, reverse-engineering undocumented infrastructure, and maintaining high availability of mission-critical security systems. It suits an independent, technically deep systems administrator with a Linux and IAM background who is comfortable working with minimal documentation or oversight.
Senior level · 5+ years · Secret clearance · Full-time
Advertised as Mid, but the requirements read as Senior.
“or” means any one of them counts — you don't need all of them.

Why we read it this way (8)
The posting title is internally contradictory: the requisition header says 'SYSTEMS ADMINISTRATOR SENIOR' while the body consistently frames the role as 'mid-level.' Advertised seniority is set to Mid based on the body's explicit framing; actual requirements (5+ years, autonomous operation, complex IAM/NAC ownership) support a Senior classification.
A Bachelor's degree is listed as required but the JD immediately offers a full substitution of 4 additional years of experience in lieu of the degree, so no minimum degree is hard-gated.
Cisco ISE and Aruba ClearPass are listed together as interchangeable NAC/IAM tools; ClearPass is captured as an alternative to ISE. RSA SecurID and LDAP are listed as distinct platforms and emitted separately.
DoD 8570/8140 IAT Level II compliance is required; CompTIA Security+ CE is the named example and is captured as the representative certification.
InfoBlox and GitLab administration appear only under Preferred Qualifications.
No work location or CBSA is specified in the posting; GDIT is a federal contractor operating across many sites. Location left blank.
The 'full-flex work week' benefit language does not constitute a remote-work offer; remote is set to false.
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.
