What this job asks for AI summary
A senior-level engineering role focused on designing, building, and integrating secure software for a mission-critical national security program. Day-to-day work spans backend and frontend development — primarily Java/Spring Boot, ReactJS, Apache Kafka, and Apache NiFi — within an Agile Scrum environment. The role suits a deeply experienced engineer holding an active TS/SCI clearance with Polygraph.

Rare in this occupation — lead with these, and say what you built with them.
Most people in this occupation already list these. Still required — just not what gets you shortlisted.
What the occupation pays Median $138,970 (middle half $107,524–$175,762). This posting is about at that midpoint.

Why we read it this way (7)
No work location or metro area is specified in the posting. Given the TS/SCI with Polygraph requirement and Leidos's primary cleared-work campuses, this role is almost certainly on-site at a classified facility (likely in the DC/Northern Virginia/Maryland corridor), but the JD does not confirm this.
The posting lists a $25,000 sign-on bonus, which is not captured in the compensation range fields.
The 'Knowledge needed' section (Spring Boot, React, Kafka, Apache NiFi, Docker/Docker Compose, Maven, SQL databases) appears as a sub-block within the Basic Qualifications section and is treated as required accordingly.
Java is listed with 'or similar programming language' — common substitutes are listed as alternatives, but the requirement for a backend language is a hard gate.
The acronyms 'CONMD' and 'CSSRC' appear at the end of the qualifications section; these appear to be internal Leidos program/contract identifiers and carry no extractable skill or requirement signal.
The posting references 'Kira' alongside Git and Confluence as common development tools; Kira is likely an internal or program-specific tool and is not a widely recognized canonical technology, so it was omitted from the skills list.
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.
