Key Responsibilities • Develop, validate, and execute modeling and simulation scenarios aligned with HHQ guidance, intelligence inputs, and operational requirements. • Build and deliver modeling products (GIANT/RPM runs, visualizations, charts, videos) tailored to Warfighter and external agency needs. • Support NAVWAR scenario development, error resolution, documentation, and compliance checks. • Conduct GIANT‑RPM QA/QC for GPS EA Frequency Request packages; support RPM modeling for EA Clearance Request timelines (120/90/75 days). • Provide Red/White/Blue Cell exercise modeling support, and assist with scenario planning and coordination with JNWC and CCMDs. • Support Electronic Attack (EA) package development and Direct Injection Testing (setup, execution, reporting). • Assist with RF antenna modeling, GNSS/M‑Code modeling, and emerging PNT threat analysis. • Participate in PNT assessments (e.g., GYPSY, FORTUNE), including planning, execution, analysis, and report contributions. Required Qualifications • Up to 3 years of experience and a BA/BS degree. • Hands‑on experience with modeling tools such as GIANT, GIANT‑RPM, STK, or similar systems. • Familiarity with NAVWAR, GNSS performance modeling, EA processes, and threat‑environment analysis. • Strong analytical skills, attention to detail, and ability to produce technically sound modeling outputs. • Ability to work within structured processes and meet tight deadlines. • U.S. Citizenship and ability to obtain/maintain required clearance. Preferred Qualifications • Experience supporting JNWC, NAVWAR, CCMDs, or GPS EA processes. • Background in RF modeling, PNT‑degraded operations, antenna modeling, or exercise support. • Experience writing technical reports, quick‑look summaries, or after‑action documentation.
