What this job asks for AI summary
A senior full-stack engineering role supporting a U.S. government customer, focused on building and maintaining end-to-end software solutions — spanning front-end interfaces, REST middleware, databases, analytics, and cloud infrastructure. The work involves rapid development of new capabilities, modernizing legacy systems, and automating mission-critical workflows. Suited to a highly experienced engineer holding an active TS/SCI clearance with Polygraph.
Senior level · 12+ years · Washington-Arlington-Alexandria, DC-VA-MD-WV · TS/SCI clearance · Full-time
Advertised as Principal, 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 is titled 'Principal Full Stack Software Engineer' but the actual requirements (12+ years experience, senior IC scope on a subcontract team) are consistent with a Senior-level role on a normal career ladder. 'Principal' here appears to be a title label rather than an org-wide technical authority designation.
A BS in Computer Science or related field is listed as a requirement, but the JD explicitly allows substitution of 4 additional years of SWE experience in lieu of the degree — so no hard degree gate applies.
The TS/SCI with Polygraph clearance is an explicit hard gate; the posting states it must be in-scope (within 7 years).
NSANet-specific platforms (MACHINESHOP, GHOSTMACHINE, C2S) and CNO/ATPG/TURBINE/ASGARD experience appear in the Key Skills and Desired Skills sections respectively. MACHINESHOP and GHOSTMACHINE are mission-specific internal tools not emitted as canonical skills; CNO/ATPG/TURBINE/ASGARD experience is listed under Desired Skills.
Bootstrap, jQuery, Asyncio, Pandas, Docker, Nginx, and GitLab CI/CD appear in the Responsibilities narrative describing the existing stack rather than in a formal requirements section — treated as preferred/context.
Claude Code, Codex, and Opencode are listed under Desired Skills as AI-assisted development tools; React, Angular, and Vue are listed under Desired Skills as modern UI libraries.
Java (Map/Reduce) is mentioned only as a legacy system the candidate may occasionally update — not extracted as a required or preferred skill given the incidental framing.
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.
