PNT Timing and Synchronization Engineer, Amazon Leo Flight Dynamics

As a member of a growing PNT team within Amazon Leo, the Time Transfer and Synchronization Engineer is responsible for designing, implementing, optimizing and monitoring high-precision synchronization architectures across terrestrial and space-based networks. You will use various time transfer protocols to achieve nanosecond-level accuracy over RF and optical links. Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Key job responsibilities -

• Design, implement, and validate time transfer systems using multiple methodologies including PTP/NTP, TWSTFT, GNSS Common View, GNSS All in View or other protocols -
• Implement time transfer over RF and optical links -
• Evaluate and integrate emerging time transfer technologies to achieve nanosecond level timing accuracy -
• Design and build an operational system to monitor the performance of clock synchronization architecture -
• Collaborate with cross-functional teams on satellite timing systems, ground gateway operations, and network time synchronization - Conduct performance analysis and troubleshooting of timing systems across distributed infrastructure
