Why we read it this way (7)
The role title is 'Information Systems Security Engineer (ISSE)' with no seniority level in the title; advertised seniority is therefore Unspecified. The 5+ years requirement and scope (ATO ownership, classified environments, hybrid cloud/on-prem architecture) support a Senior classification.
SOC code 15-1212 (Information Security Analysts) was chosen as the primary occupation given the dominant focus on security compliance, accreditation (ATO/RMF), STIG application, and vulnerability management. 15-1244 is noted as a runner-up because the role also involves hands-on Kubernetes and Linux system hardening/operations.
The clearance requirement is stated as 'Active TS clearance, SCI eligible required' — mapped to TopSecretSci.
UDS Core, OpenShift, and Rancher appear together under the 'Desired' section as interchangeable Kubernetes distribution examples; emitted as a single preferred skill with alternatives.
CI/CD, DevSecOps, and Terraform appear in the 'Why Join Us' stack narrative and/or the 'Desired' section — treated as preferred rather than hard gates.
The compensation range ($130,000–$170,000/year) is explicitly stated as applicable to the Colorado area only.
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.
