Why we read it this way (9)
The title includes '(SME)' — Subject Matter Expert — which is a seniority signal but not a standard band label; the role is classified Senior based on the 15+ years experience requirement and scope of work.
The posting requires an active TS/SCI with Polygraph as a hard gate ('The position requires an active TS/SCI with Polygraph security clearance').
Degree requirement: the JD accepts 'Bachelor's or Technology degree OR equivalent 19 years job-related experience', so no degree is hard-gated.
The firewall vendor requirement lists Cisco, Palo Alto, or Juniper as interchangeable options; Palo Alto Firewall is used as the primary name with the others as alternatives. Cisco ASA/NGFW is also listed separately with its own 12-year requirement.
The SOC code is Medium confidence: the role is primarily network engineering/operations (designing, configuring, and maintaining network infrastructure), which maps best to 15-1244. However, the depth of design and architecture work could also support 15-1299 (Computer Occupations, All Other) as a network architect framing.
Routing protocols (EIGRP, OSPF, BGP, IP MPLS) are listed together as a 'thorough understanding' requirement; each is emitted as a separate must-have skill since they are distinct technologies used concurrently, not interchangeable alternatives.
Desired Qualifications (QoS LAN/WAN, Juniper/Palo Alto/Cisco NGFW certifications, MFA, Zero Trust) are marked preferred.
The salary range of $191,250–$258,750/year is stated as a likely range, not a guarantee.
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.
