Primary Duties and Responsibilities (Essential Functions)

• Provide deep engineering expertise across the missile warning ground processing, mission management, and operational delivery threads.
• Provide senior engineering judgment to one of the most consequential mission lines in Space Sensing — the systems that turn satellite-detected threats into actionable missile warning to the President, the Secretary of Defense, combatant commanders, and warfighters in real time.
• Lead engineering reviews of ground processing architectures, mission management systems, and operational software baselines.
• Support development planning for next-generation missile warning ground capabilities, including Next-Gen OPIR ground processing.
• Contribute to engineering analyses of end-to-end missile warning latency, accuracy, and reliability.
• Engage with contractor program teams developing or sustaining missile warning ground processing and mission management capabilities.
• Review and contribute to engineering change proposals, technical baseline reviews, and operational software change boards.
• Provide engineering oversight for integration of missile warning ground with satellite and user segments.
• Prepare technical briefings, engineering position papers, and operational readiness assessments for senior Government audiences.

Required Qualifications and Experience

• Active Top Secret clearance with SCI eligibility.
• U.S. Citizenship.
• Bachelor's degree in Aerospace Engineering, Electrical Engineering, Computer Engineering, Computer Science, Systems Engineering, Physics, or a closely related discipline from an ABET-accredited institution.
• Minimum 15 years of progressively responsible aerospace engineering experience, with demonstrated SME-level depth in missile warning systems, satellite ground processing, or mission management systems.
• Demonstrated experience with DoD missile warning, SBIRS, Next-Gen OPIR, or related strategic sensing missions.
• Experience with operational ground software baselines, mission management, and 24/7 operational delivery.
• Strong written and verbal communication; demonstrated ability to brief senior Government audiences.

Preferred Qualifications

• Master's degree or PhD in a technical discipline.
• Prior direct support to SSC/SN, SMC, NORAD/USNORTHCOM, or predecessor Space Force / Air Force missile warning organizations.
• Direct experience with SBIRS Mission Control Station, Next-Gen OPIR ground, or legacy missile warning ground modernization.
• Operational missile warning crew or crew-supervisor experience.

Expected Salary Range

$190,000 to $240,000 per year.
