SME System Engineers to provide SETA (Systems Engineering & Technical Assistance) support to a government program office responsible for the development and deployment of a space-based Air Moving Target Indicator (AMTI) system.

This role places you at the center of a high-visibility, fast-paced program, working directly with government leadership and industry partners to ensure mission success. You will provide independent technical assessment, systems engineering expertise, and mission-focused insight across the full lifecycle from design through launch and early operations.

If you're a technically strong engineer who thrives in a government advisory role, understands how to bridge government and industry, and wants to contribute to a next-generation space-based radar mission, we encourage you to apply.

In this role, you will:

• Provide independent technical assessment of contractor designs, architectures, and performance
• Support systems engineering lifecycle activities, including requirements development, design reviews, integration, test, and verification
• Evaluate radar payload performance, modeling, and system‑level trade studies
• Assess RF hardware development and production testing
• Support Model-Based Systems Engineering (MBSE) and digital engineering efforts, including system performance modeling and multi‑sensor integration
• Analyze and validate end‑to‑end mission performance (sensor, ground, processing, dissemination)
• Participate in and support major program design reviews
• Provide technical risk identification and mitigation recommendations to government leadership
• Develop and deliver briefings and decision support materials for senior stakeholders
• Collaborate with government and contractor teams using tools such as Cameo, Tableau, and Confluence

If you're suitable for this role, you have:

• Bachelor’s degree in aerospace engineering, Electrical Engineering, Physics, or related technical field (Master’s or PhD preferred)
• Active Top Secret SCI with CI Poly or the ability to get a CI Poly after hire
• 10+ years of experience in aerospace, space systems, or defense programs
• Demonstrated experience across the full system lifecycle (requirements, design, integration, test, and operations)
• Strong background in space‑based ISR systems, radar systems, or RF payloads
• Experience with one or more of the following:
  • Radar system design or radar signal processing
  • RF payload development and production testing
  • Performance modeling and estimation (e.g., detection, tracking, coverage)
  • Mission data processing or ground system architectures
• Experience with Model-Based Systems Engineering (MBSE) and SysML tools (e.g., Cameo/Magic Draw)
• Ability to assess contractor technical performance and provide independent recommendations
• Strong written and verbal communication skills, including experience briefing senior leadership

• Prior experience supporting a government program office (SETA or similar role)
• Familiarity with DoD/IC acquisition processes (JCIDS, DoD 5000 series)
• Experience working with prime contractors and major subcontractors
• Background in:
  • Satellite and payload engineering
  • Communications systems and architectures
