• Support integration, verification, and validation activities for GPS receiver hardware and software.
• Participate in white box and black box testing activities to verify system functionality, security, and performance.
• Evaluate cryptographic implementations, information assurance requirements, and system security protocols.
• Perform security impact assessments and provide technical recommendations to support Program Office decision-making.
• Review and interpret GPS Interface Control Documents (ICDs), Technical Requirements Documents (TRDs), and engineering specifications.
• Monitor and assess developmental and operational test execution while identifying technical risks and recommending corrective actions.
• Collaborate with government customers, FFRDCs, vendors, and cross-functional engineering teams to achieve program objectives.
• Support technical interchange meetings, design reviews, and acquisition milestones.
• Prepare engineering documentation, technical reports, briefings, and program deliverables.
• Travel up to 15% as required to support customer meetings and test events.

Basic Qualifications

• Bachelor's degree in Engineering, Computer Science, Mathematics, Physics, or another technical discipline.
• 7+ years of experience as a Systems Engineer, Systems Integration Engineer, Test Engineer, Test Manager, or Lead Tester supporting DoD programs.
• 5+ years of experience developing or reviewing test plans, procedures, reports, test vectors, and verification strategies.
• 5+ years of experience supporting DoD Integration and Test activities.
• 5+ years of experience with cryptography, information assurance, or secure systems engineering.
• Experience with white box and black box testing methodologies.
• Knowledge of military GPS systems, Positioning, Navigation, and Timing (PNT) technologies, and GPS receiver architectures.
• Ability to interpret GPS Interface Control Documents (ICDs) and Technical Requirements Documents (TRDs).
• Knowledge of security protocols and secure system engineering principles.
• Experience supporting technical discussions with government customers, vendors, and engineering stakeholders.
• Ability to communicate effectively across multidisciplinary engineering teams while working independently on complex technical efforts.
• Proficiency with Microsoft Office (Word, Excel, PowerPoint, Outlook, Teams) and collaborative project management tools.
• Active Secret Security Clearance.

Preferred Qualifications

• Experience supporting Military GPS User Equipment (MGUE) programs.
• Experience with GPS satellite simulators.
• Experience supporting Lead Developmental Test Organizations (LDTO) or Operational Test Authorities (OTA).
• Experience with Agile software development methodologies.
• Familiarity with DoD acquisition and systems engineering processes.
• Experience performing systems integration for space or defense systems.
• Model-Based Systems Engineering (MBSE) experience.
• TS/SCI Security Clearance.
