Senior L1/L2 Embedded SW Architect, Wireless Systems

Project Kuiper 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 Systems Engineer, this role is primarily responsible for the design, development and integration of Ka band and S/C band communication payload and customer terminal systems.

The Role will be a part of the team defining the overall communication system and architecture of Project Kuiper's broadband wireless network. This is a unique opportunity to innovate and define novel wireless technology with few legacy constraints. The team develops and designs the communication system of Kuiper and validates its overall system level performance within key metrics such as throughput, latency, system availability, packet loss etc.

This role in particular will be responsible for leading the software architecture design and implementation of the modem firmware.

This role will also play a critical role in the design, integration and verification of various HW and SW sub-systems as a part of system integration and link bring-up and verification.
