What this job asks for AI summary
A systems engineering role focused on Electronic Warfare (EW) mission systems for US Government and foreign military programs at CACI. The engineer will lead requirements development, define system and software architectures, decompose functional requirements across software, hardware, RF, and signal processing disciplines, and serve as the primary technical interface between system-level and specialized engineering teams. The position is hybrid/on-site at either Florham Park, NJ or Westminster, CO.
Senior level · 7+ years · New York-Newark-Jersey City, NY-NJ-PA · Bachelor's required · TS/SCI clearance · Full-time

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 $131,162 (middle half $100,145–$164,745). 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 Aug 18, 2026. It is a model, not a headcount.
Why we read it this way (8)
The posting lists two possible work locations: Florham Park, NJ and Westminster, CO (Denver metro). The CBSA reflects the NJ location as the first listed; the Denver-Aurora-Lakewood, CO CBSA (19740) is an equally valid alternative.
The clearance situation is nuanced: the posting states 'Minimum Clearance Required to Start: None' but requires US Citizenship and the ability to obtain TS/SCI, and lists an active TS/SCI as a preferred/desired qualification. The role is classified as requiring TS/SCI because candidates must be able to obtain it as a condition of employment.
SOC classification is a judgement call. This role is primarily systems engineering — defining requirements, architectures, and interfaces — rather than hands-on software development or pure IT analysis. 15-1211 (Computer Systems Analysts) is the closest available code, though 15-1299 (Computer Occupations, All Other) is a reasonable alternative given the defense/EW systems engineering focus.
The salary range ($108,400–$227,500) is very wide, reflecting CACI's note that geography, contract labor categories, and experience all influence final pay.
Open systems architecture standards (CMOSS, SOSA, FACE) are listed under Desired Qualifications and are grouped as interchangeable familiarity items rather than distinct hard requirements.
Formal design review familiarity (SRR, PDR, CDR, TRR) is listed under Desired Qualifications with no specific tool named, so it is omitted from the skills list per the guideline against generic methodologies without a concrete named technology.
Ignored 4 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Systems Engineering, Requirements Development, Software Architecture, Automated Test Development.
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.
