We read this from the posting text with AI. Skim the description below before ruling yourself out.
How this req sits in the market our data
Most people in this occupation already list these. Still required — just not what gets you shortlisted.
What the occupation pays Median $158,337 (middle half $126,441–$180,105). This posting is about at that midpoint.
Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Jul 28, 2026. It is a model, not a headcount.
Why we read it this way (8)
The posting advertises openings 'across a range of experience levels' with no stated minimum years of experience and a very wide salary band ($114K–$247.9K), making it impossible to pin down a single seniority level. Mid is chosen as the conservative default; the actual hire could range from Mid to Senior depending on the candidate selected.
An active TS/SCI with Polygraph is explicitly listed as a hard qualification gate — candidates without it cannot be considered.
AWS is listed as 'preferred' in the cloud-environment requirement but sits within the Qualifications block, which gates on cloud production experience generally; AWS is captured as required (with alternatives) reflecting the hard gate on cloud experience, with AWS being the preferred platform.
The cloud-environment requirement is stated as 'experience developing production applications in cloud environments; AWS experience preferred' — the hard gate is on cloud experience broadly, with AWS as the preferred flavor.
Node.js backend frameworks (Express/NestJS) appear in both the narrative and the Desired Skills section, confirming they are preferred, not required.
Testing frameworks (Vitest, Playwright, Pytest) are listed together under Desired Skills; they are interchangeable in the sense that experience with any one satisfies the preference, so they are grouped as alternatives.
The role requires primary residence within a two-hour drive of Herndon, VA for onsite collaboration — it is not fully remote.
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.
