Embedded Software Engineer, Amazon Leo Satellite Broadband Terminals

Amazon Leo is closing the digital divide with a constellation of 3236 low-Earth-orbit (LEO) satellites bringing fast affordable broadband to communities the internet has never reliably reached. The customer terminal is the phased-array antenna at the customers premises that turns that constellation into a working internet link and our team writes the embedded software that makes it work: acquiring a LEO satellite on a fast overhead pass electronically steering the beam to track it closing and holding the link and handing over to the next satellite within seconds. This is a broad role you can work across the full signal chain and go deep wherever interests you most.

What youll work on:
Electronic beam steering & tracking real-time control that keeps a phased-array beam pointed at a fast-moving satellite across the pass and through every handover.
Phased-array calibration per-element amplitude/phase calibration that holds beam and sidelobe performance across unit-to-unit variation temperature and frequency on real hardware in the field with the automated test coverage to keep it reliable.
Link acquisition tracking & management satellite acquisition closed-loop tracking and the control that brings the link up keeps it healthy and reacquires cleanly through handovers.
RF power & thermal management managing transmit power and duty cycle against PA and platform thermal limits so the terminal runs at full performance without exceeding its envelope.
System integration & field telemetry integrate the RF front-end controls and signal path then use device telemetry to debug and improve terminals operating on orbit.

Key job responsibilities
What we look for:
Embedded C/C or Rust on Linux/RTOS close to the hardware.
Wireless / RF / DSP exposure phased arrays beamforming SatCom 5G/LTE radar or similar or strong drive to grow into it.
Hands-on hardware debugging comfortable with lab instruments RF test setups and reading telemetry to reason about a live system.

Our stack:
Rust C/C and Python on embedded Linux / RTOS working directly with the RF front-end and real hardware lab terminals RF test benches and satellites on orbit. Automated hardware-in-the-loop testing and rich fleet telemetry let you see the impact of your code in the real world. New development is increasingly in Rust.

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.
