About The Position

Amazon LEO is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world. Amazon LEO will help close the digital divide by delivering fast, affordable broadband to a wide range of customers, including consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity. As a Sr. Mobility Terminal System Engineer, you will be responsible for mobile terminal architecture, integration, and validation with hardware, software, and firmware. You will work in a collaborative environment with a multi-disciplinary team. As a Sr. Mobility Terminal System Engineer on the Leo Customer Terminal (CT) team, you will work daily with electrical, hardware, RF, antenna, silicon, and product design engineers, as well as software and operations teams in a collaborative environment. Your focus will be on architecting, integrating, and validating the mobility terminal's system-level performance so it can be successfully productized for aviation, maritime, and automotive customers. The Leo Customer Terminal team is responsible for developing both outdoor & indoor devices, enabling customers internet service via the Leo satellite network. We own the entire process from early prototypes through mass production including requirements documents, architecture definition, hardware development, and all integration/verification testing.
