About The Position

Amazon Leo is an initiative to launch a constellation of Low Earth Orbit
satellites that will provide low-latency, high-speed broadband connectivity to
unserved and underserved communities around the world.

As a Sr. PIT RF Communications System Payload Integration and Test Engineer, you
will engage with an experienced cross-disciplinary team to design and test
innovative product solutions. You will work closely with colleagues throughout
Leo’s inter-disciplinary team and engage third party suppliers in order to drive
key aspects of product definition, execution, and optimization. You must be
responsive, flexible and able to succeed within a collaborative and fast-paced
environment.

As a member of the Payload Integration and Test team, you will be responsible
for verification and validation of the entire wireless system composed of
multiple wireless components. This includes testing, analyzing, and optimizing
RF systems from baseband modems to RF transceivers to phased-array antennas.
