Senior Systems Engineer

The job location is not explicitly stated in the posting. Given the USSF/SSC (Space Systems Command) mission context, the role is likely based in the Los Angeles/El Segundo, CA area (SSC HQ) or Peterson SFB, CO, but this cannot be confirmed from the text alone.

SOC classification is uncertain: this role is a defense/government systems engineering position focused on space electronic warfare acquisition and sustainment — it spans systems analysis (15-1211), program/acquisition support, and domain-specific engineering. 15-1211 is the closest fit; 15-1299 is noted as a runner-up given the specialized defense-systems nature of the work.

The 15-year experience requirement is the primary gate; the posting explicitly allows substitution with a Master's (7.5 years) or PhD (3 years), so the floor is degree-dependent. The 15-year figure is used as the overall years minimum per the Bachelor's path.

Active TS clearance with SCI eligibility is a hard requirement per the 'Clearance' section.

Skills listed under 'Required' are largely methodological/domain areas (requirements development, architectures, systems integration, T&E, verification & validation) rather than named software tools — these are captured at the category level as the JD names no specific tools.

Agile, CSEP, space EW experience, STTR experience, and Combatant Command experience all appear under the 'Desired' section and are marked as preferred.

Valid US passport and willingness to travel overseas is listed as desired, not a hard gate.

A STEM Master's in Systems Engineering is listed as desired, not required — the hard degree gate is a Bachelor's with 15 years.

Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): systems engineering, requirements 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.
