What this job asks for AI summary
This role centers on maintaining and modernizing NiagaraFiles, an intelligence community application built on Apache NiFi. Day-to-day work involves building NiFi microservices, refactoring existing components for improved performance and scalability, and migrating or optimizing software within an AWS cloud environment. It suits a highly experienced Java engineer who holds an active TS/SCI clearance with Polygraph.

How this req sits in the market our data
What the occupation pays Median $138,970 (middle half $107,524–$175,762). 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 (10)
The posting requires 20 years of software engineering experience, which is unusually high; however, the role's scope and responsibilities align with a Senior individual-contributor band rather than Staff or Principal — the JD describes component-level development and refactoring work, not org-wide technical direction.
Location is not explicitly stated in the posting. Given the IC/NiagaraFiles context and the TS/SCI with Polygraph requirement, this is almost certainly a cleared facility in the Washington DC metro area, but no city or CBSA could be confirmed from the text alone.
Telework is permitted up to two days per week, so the role is NOT fully remote.
A Bachelor's degree in Computer Science or related field is listed as required, but the JD explicitly allows substitution with four additional years of experience in lieu of a degree — degree requirement is therefore treated as None.
The TS/SCI clearance requirement includes a Polygraph ('active TS/SCI security clearance with Polygraph is required').
JUnit and Mockito appear together under Desired Qualifications as a single testing-framework requirement; Mockito is captured as an alternative to JUnit rather than a separate skill.
Kubernetes and Docker appear together under Desired Qualifications as containerization tools; Docker is captured as an alternative to Kubernetes.
Apache NiFi and NiagaraFiles are listed together under Desired Qualifications; NiagaraFiles is a proprietary IC-specific application built on NiFi, so Apache NiFi is used as the canonical skill name.
All skills under 'Desired Qualifications' are marked as preferred.
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.
