What this job asks for AI summary
A systems engineering role focused on designing, developing, and testing software applications for a U.S. missile defense command-and-control system. Day-to-day work involves decomposing system requirements, supporting software integration, debugging, and collaborating with systems engineering teams on interfaces, use cases, and architecture artifacts. Suited to engineers with at least three years of systems engineering experience and an active or obtainable DoD Secret clearance.

We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (9)
The role title is 'Software Systems Engineer' and the work blends both software development and systems engineering (requirements decomposition, interface control, use cases, CONOPS). The primary day-to-day work leans toward software development/integration, but a systems analysis classification (15-1211) is a credible alternative — hence Medium confidence.
No specific work location city is stated; the posting references multiple states for pay-range purposes (CA, MA, NY, CO, HI, IL, MD, MN, NJ, VT, WA, DC) and notes the role is fully onsite at a designated Lockheed Martin facility. No CBSA could be determined.
The degree requirement is listed as 'may have a post-secondary degree or training' — this is not a hard gate, so the degree requirement is set to None.
The salary range ($89,300–$157,550/year) is explicitly stated as applicable to specific states; the actual range may differ for other locations.
A final DoD Secret clearance is listed as a Basic Qualification (hard gate). Candidates must be US citizens.
All 'Desired Skills' items (Unix/Linux, automated testing, pipeline development, software integration testing, performance modeling, build management tools, MBSE, prior C2BMC experience) appear under the 'Desired Skills' heading and are treated as preferred.
Systems engineering artifacts (specifications, ICDs, Use Cases, System Architecture Descriptions, Trade Studies) are listed as required under Basic Qualifications; individual artifact types are captured as representative required skills.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): systems engineering, performance modeling, build management.
Requires a Secret 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.
