APNT Systems Engineer

Job Description
: IS4S is seeking highly skilled and motivated Systems Engineer to support the development, integration, and verification of assured Positioning, Navigation, and Timing (PNT) systems working on-site in our Auburn, AL or Huntsville, AL location. The successful candidate will contribute to the design and development of resilientnavigation and timing solutions for platforms operating in challenging environments, including environments where GPS/GNSS may be degraded, denied, orunavailable.

This role offers the opportunity to work across the systems engineering lifecycle, from translating operational needs into system requirements to developing test plans, conducting system-level testing,verifying performance, and integrating PNT capabilities onto operationalplatforms. The ideal candidate has a strong engineering foundation, excellent problem-solving skills, and an interest in navigation, sensors, embedded systems, and resilient system architectures.

• Develop,decompose, and manage system and subsystem requirements, including requirements traceability and interface definitions.
• Support system architecture development, technical analyses, and trade studies to evaluate design alternatives and system performance.
• Develop and execute test plans and procedures to verify and validate system requirements.
• Analyze test data, troubleshoot system deficiencies, and document results and corrective actions.
• Support hardware and software integration of PNT sensors and subsystems ontooperational platforms.
• Participate in laboratory testing, hardware-in-the-loop testing, field trials, and platform-level demonstrations.
• Prepare and maintain technical documentation, including requirements specifications,interface documents, test procedures, and verification reports.
• Collaborate with multidisciplinary engineering teams to resolve technical challenges and support system development throughout the engineering lifecycle.

• Bachelor’s or Master’s degree in Systems Engineering, Electrical Engineering, Aerospace Engineering, Mechanical Engineering, Computer Engineering, or a related engineering discipline.
