Amazon Position Navigation Timing Engineer Project Kuiper 

United States, Washington, Redmond 

451095715

Key job responsibilities
This position requires experience in simulation and development of terrestrial navigation and timing system composed of GNSS (Global Navigation Satellite System) receivers, IMU (Inertial Measurement Unit) sensors and local oscillators. A successful candidate will work on flight embedded software and terrestrial systems.Working with the Kuiper engineering team, you will:
• Support conceptual design of PNT systems
• Develop simulation tools to assess expected performance
• Own and operate HITL (Hardware In The Loop) tests on PNT systems
• Perform field tests and performance assessments of PNT systems
• Develop software tools to automate data analysis
• Work closely with RF, GNC and software engineers to improve PNT system performanceExport Control Requirement:

- Master’s degree in Aerospace Engineering, Electrical Engineering, Geomatics Engineering, or related field OR 3+ years of software engineering experience
- Experience with GNSS fundamentals
- Experience with IMU sensors

- PhD degree in Aerospace Engineering, Electrical Engineering, Geomatics Engineering, or comparable experience
- Experience with accelerometer, gyro and magnetometer data calibration and processing filter (Extended Kalman Filter) development
- Experience with AHRS (Attitude and Heading Reference System)
- Experience with GNSS systems, including processing raw measurements such as pseudoranges and carrier phases
- Experience with GNSS positioning engine development or software defined GNSS receiver development
- Experience with various types of oscillators (TCXO, OCXO, etc) characterization and performance assessment
- Experience with resilient PNT or RAIM (Receiver Autonomous Integrity Monitoring)
- Graduate school level understanding of frequency references
- Graduate school level understanding of PNT systems
- Excellent communication skills
