the PNT Engineer provides technical input and subject matter expertise during proposal, capture, and tender phases. In this role, you will be responsible for: Systems Engineering & Architecture - Gather, analyse and formalise internal and external stakeholders' needs relating to resilient PNT systems. - Define end-to-end PNT system architectures integrating GNSS, INS, IMUs, aiding sensors (odometers, altimeters, computer vision), atomic clocks, time servers and Navwar software. - Develop and maintain PNT architecture, design, and interface documentation, including SAD, SSDD, and interface control documentation. - Develop simulation environments to characterize PNT solution performance and robustness. PNT Engineering - Knowledge on Safran's Inertial Navigation product lines (INS, IMU, gyroscope and accelerometer sensors), address questions and provide training to customers and industry partners. - Knowledge on Safran's Timing product lines (clocks, time servers), address questions and provide training to customers and industry partners. - Design, integrate and support PNT solutions for trials, demonstrations and trade shows, including inertial navigation, PPS generation, UTC traceability, clock disciplining, and holdover strategies. - Support alternative and complementary PNT techniques, including inertial-only navigation, terrain aiding, celestial navigation, and signals of opportunity. - Contribute to assured PNT strategies for operation in GNSS degraded or contested environments. **But what else? (advantages, specificities, etc.)** In this role, you will be responsible for: (continued) GNSS and Navwar Engineering - Knowledge on Safran's GNSS product lines (receivers, antenna, interference detection and mitigation software), address questions and provide training to customers and industry partners. - Design, integrate, and support GNSS receivers, antenna and simulation solutions for trials, demonstrations and trade shows, including single and dual frequency and multi-constellation systems (GPS, Galileo, GLONASS, etc). - Analyse GNSS signal structures, propagation effects,



and error mechanisms with Safran's Navwar software SKYDEL. - Support compliance with relevant GNSS, navigation, and timing standards. - Design and support mitigation strategies against GNSS jamming, spoofing, and interference. Verification, Validation & Test - Define verification strategies, test plans, and acceptance criteria for PNT systems and functions. - Establish and maintain Verification Cross-Reference Matrices (VCRM). - Plan, execute, and support verification activities including Acceptance Test Plans (ATP), Acceptance Test Procedures (ATProcs), and Acceptance Test Reports (ATR). - Support laboratory, field-, and flight-testing activities. - Analyse test data and validate navigation and timing performance against system requirements. - Produce technical reports, compliance evidence, and verification documentation. **Candidate skills & requirements** To be successful in this role you must have: - Bachelor's degree or higher in Engineering (Aerospace, Electrical, Mechatronics, Robotics, Systems Engineering, or related discipline). - Demonstrated experience in systems engineering, including requirements management, system architecture, integration, and verification and validation (IV&V;). - Hands-on experience with GNSS, INS, IMUs, sensor fusion, and supporting laboratory, field, and or flight testing. - Familiarity with Defence acquisition frameworks such as ASDEFCON and experience with safety- or mission-critical systems in regulated environments is highly desirable. SECURITY REQUIREMENTS: Applicants must be eligible to obtain and maintain an Australian Defence security clearance. Core Technical Skills - Systems engineering and product development life cycle. - Global Navigation Satellite Systems (GNSS): GPS, Galileo, GLONASS, etc. - Inertial Navigation Systems (INS). - Inertial Measurement Units (IMU), including MEMS, FOG, and RLG technologies. - Sensor fusion and estimation theory. - Timing systems and clock management. - Kalman filtering techniques, including Extended and Unscented Kalman Filters (EKF, UKF). Software & Tools - MATLAB and Simulink. - Python and/or C/C++. - Embedded software fundamentals. - Navigation modelling and simulation tools. **Job location** **Job location** Oceania, Australia, New South Wales **City (-ies)** BOTANY **Applicant criteria** **Minimum education level achieved** Bachelor's Degree **Minimum experience level required** More than 5 years
