Support the development of next-generation defense and radar systems by ensuring mission-critical hardware and software are designed, tested, and operated safely throughout the system lifecycle. Join a multidisciplinary engineering team responsible for applying system safety engineering principles to identify hazards, mitigate operational risk, and ensure compliance with military safety standards supporting advanced defense programs.

• Perform comprehensive system safety analyses throughout the system development lifecycle, ensuring hardware, software, and operational concepts comply with military system safety standards.
• Evaluate system designs, engineering documentation, operational procedures, and support equipment to identify hazards and develop effective risk mitigation strategies.
• Apply MIL-STD-882E system safety processes to analyze hazards, assign risk levels, and drive safety requirements into system architecture, software, hardware, and operational procedures.
• Develop and maintain System Safety Program Plans (SSPPs), System Safety Assessment Reports (SARs), Software Safety Analyses, hazard analyses, and other required safety documentation supporting customer and range certification requirements.
• Maintain and manage Hazard Tracking System (HTS) records, ensuring hazards are documented, mitigated, verified, and closed through a disciplined lifecycle process.
• Participate in system design reviews, technical interchange meetings, and engineering peer reviews to ensure safety is incorporated early in the design process.
• Collaborate daily with systems engineers, software developers, hardware engineers, integration teams, and program leadership to resolve safety concerns and implement corrective actions.
• Perform operational safety audits and assessments to evaluate program compliance and identify opportunities for continuous improvement.
• Support accident and incident investigations by identifying root causes, documenting findings, and recommending corrective and preventive actions.
• Verify compliance with applicable military, customer, and regulatory safety standards while balancing technical performance, mission requirements, schedule, and program cost.
• Support requirements development, system verification, validation, and test activities by ensuring safety requirements are fully traceable throughout the engineering lifecycle.
• Support occasional travel (up to 10%) for customer meetings, engineering reviews, and program activities.

• Bachelor's degree in Safety Engineering or a related STEM (Science, Technology, Engineering, or Mathematics) discipline from an accredited university and 5 years of related experience; OR
• Master's degree and 3 years of related experience; OR
• PhD and 1 year of related experience.
• Four additional years of relevant experience may be substituted in lieu of a degree.
• Active in-scope DoD Secret security clearance required at time of application.
• Experience applying MIL-STD-882E system safety processes to identify, assess, mitigate, and eliminate system hazards.
