What this job asks for AI summary
A technical lead role at a federal systems integrator focused on designing and operating Live, Virtual, and Constructive (LVC) modeling and simulation environments for a defense program called Ironwood. The position oversees a small multidisciplinary engineering team, drives digital engineering and MBSE architecture, integrates third-party simulation tools, and leads end-to-end LVC event planning, testing, and execution. Candidates with deep M&S experience, DoD simulation standards (HLA/DIS), and an active TS/SCI clearance are the target profile.

Why we read it this way (8)
No work location is specified in the posting; the CBSA and state fields are left blank. The role's defense/LVC nature and TS/SCI requirement strongly suggest an on-site position at a government facility, but no city or state is named.
The title used in the posting is 'Technical Lead for Systems Engineering' / 'Chief Systems Engineer of LVC Mod & Sim Environments' — neither carries an explicit seniority level word, so advertised seniority is Unspecified. The 10+ years overall and 8+ years M&S requirements support a Senior classification.
SOC classification is Medium confidence. The role blends systems engineering, MBSE modeling, simulation architecture, and some software development (containerization, programming languages). 15-1299 (Computer Occupations, All Other) is the best fit for a systems/simulation engineer of this type; 15-1252 (Software Developers) is a plausible runner-up given the coding and DevSecOps responsibilities.
The Qualifications section lists Omniverse, Postman, and Visual Studio alongside programming languages and Docker/Kubernetes under the same required block, so they are treated as hard gates despite being less central to the role.
ModelCenter and SysML appear in the Requirements section but are framed with 'and/or' alongside other tools, suggesting some optionality; they are marked preferred. Cameo/SysML is listed together but Cameo Systems Modeler is the primary named product.
Märzen TDACS and TacMap 3D appear only under Desired Qualifications and are marked preferred.
The degree requirement accepts BS, MS, or PhD — the minimum is a Bachelor's degree.
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.
