Senior Systems Engineer at General Dynamics Mission Systems, Inc

The role is titled 'Systems Engineer' with no seniority modifier in the title, hence advertised seniority is Unspecified; however, the 8+ years requirement and the scope (mission-critical NSA-certified cybersecurity devices, cross-functional team leadership, CONOPS/specification authorship) firmly support a Senior classification.

SOC classification is Medium confidence: the role is a defense/cybersecurity Systems Engineer performing requirements analysis, functional analysis, trade studies, and system integration/testing — closest to Computer Systems Analysts (15-1211), though 15-1299 (Computer Occupations, All Other) is a reasonable runner-up given the specialized systems engineering focus.

All named technologies (MBSE, Full Stack, DOORS, Linux, Agile) appear under 'preferred skills or experiences' or 'Nice to have' sections — none are hard-gated in the Basic Qualifications block, which specifies only degree and years of experience.

Networking experience (Layer 2 and Layer 3) is listed under 'Nice to have' but names no specific tool or platform, so it is captured via the Linux/Networking context; no separate named tool was emitted.

A DoD Secret clearance is explicitly required at time of hire — this is a hard gate. U.S. citizenship is also required.

The position is fully on-site at the Dedham, MA facility (part of the Boston metro CBSA).

The salary range ($173,236–$182,710/yr) is described as a 'typical' estimate; actual pay may vary.

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.
