• Lead system-level evaluations during early-to-mid program milestones, including Preliminary Design Reviews (PDR) and Critical Design Reviews (CDR).
• Perform deep-dive evaluations into ground concepts and module interactions. (Note: This is a system architecture and oversight role; hands-on code development or line-by-line code audits are not required).
• Oversee contractor testing execution and V&V activities to verify that ground system performance satisfies mission requirements prior to operational fielding.
• Drive rapid technical resolution and balance program trade-offs to keep the program on track for accelerated fielding.

Required Qualifications:

• A minimum of 10 years of experience in Space Ground Systems Engineering, Ground Segment Architecture, or SETA/Advisory support.
• Strong background in Satellite Command & Control (C2), Telemetry, Tracking & Command (TT&C), Spacecraft Health & Status, or Mission Management.
• Demonstrated experience evaluating contractor performance through PDR, CDR, ICD development, and V&V/testing phases.
• Understanding of high-level system-of-systems integration and network interfaces.
• Familiarity with modern enterprise cloud architecture paradigms (AWS/Cloud frameworks, microservices, containerized deployments like Kubernetes) to effectively evaluate ground system designs.
• TS/SCI CI Poly

Preferred Qualifications:

• Experience working on rapid acquisition programs or fast-paced operational deployments.
