Why we read it this way (7)
Active TS/SCI with Polygraph is an explicit hard gate for this role.
The role is primarily backend software development in Rust, but carries unusually deep networking requirements (TCP/IP, routing, subnetting, VPN, DNS, firewalls, network segmentation) that could also fit a network/systems engineer profile — hence the runner-up SOC.
AWS CDK and infrastructure-as-code are framed with 'familiarity with' language, making them preferred rather than hard gates.
The posting lists three possible work locations (Arlington VA, Herndon VA, Jessup MD) — all fall within the Washington DC metro CBSA. The role is on-site (no remote option stated).
No degree requirement is stated anywhere in the posting.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): cloud-native design patterns.
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.
