FPGA Modem and Physical Layer Development Engineer, Amazon Leo

Create high-performance FPGA solutions to support next-generation modem systems from LEO satellites. This is a unique opportunity to define and implement a state-of-the-art wireless communication system with a focus on an ultra-reliable low-latency high-throughput physical layer (PHY). The FPGA Design Engineer will work closely with systems teams to define develop and release FPGA-based signal processing and modem solutions using latest generation hardware and modern design methodologies.

Key job responsibilities
In this role you will design implement and support a wireless modem on a ARM/FPGA system-on-chip platform. Key responsibilities include:
End-to-End RTL Development: Create and release RTL code through the full development lifecycle: system architecture definition RTL design physical implementation timing closure and simulation validation.
System Integration: Collaborate with Digital Communications and RF system architects to implement complex logic functions such as signal detection and synchronization channel coding (LDPC/Polar) beamforming or massive MIMO processing.
Cross-Functional Collaboration: Work with HW FW and SW teams to bring up and test integrated systems combining FPGA RF front-ends and networking stacks.
Architectural Trade-offs: Drive trade-off analysis to optimize FPGA resources for cost size power and performance to meet stringent 5G latency and throughput requirements.
Validation: Conduct lab-based silicon validation using high-speed signal generators and analyzers to ensure modem performance meets throughput and reliability metrics

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.
