Why we read it this way (7)
The title is 'Network Engineer Tier 3' but the posting explicitly frames it as a 'Senior Network Engineer' role — advertised seniority is Senior accordingly.
The degree requirement states 'Bachelor's degree … or equivalent work experience', so no hard degree gate applies.
TS/SCI with Polygraph is explicitly required to start.
Cisco and Juniper are listed together as examples of enterprise network equipment; Juniper is captured as an alternative to Cisco rather than a separate required skill.
Networking certifications (JNCIA, JNCIP, CCNA, CCNP) and ITIL are listed under the 'Desired' section and are marked preferred.
The SOC classification is Medium confidence: the role is primarily operational/administrative (troubleshooting, maintaining, configuring network infrastructure) rather than building new software, which points to 15-1244; however, the design and architecture responsibilities could support 15-1299 (Network Architects), noted as the alt code.
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.
