Senior Modem Engineer, Satellite Communication

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.

In this role you will:

. Engage with modem system teams to translate system-level requirements into hardware specifications and RTL implementation.

• Collaborate with system architects on SoC subsystem integration, including IP block configuration, instantiation, and interface validation.
• Support synthesis, static timing analysis (STA), and timing closure activities to meet performance and power targets.
• Contribute to low-power design implementation and verification, including power domain definition and UPF/CPF development.
• Work with verification, physical design, and firmware teams to ensure design quality and first-time-right silicon.
• Develop and maintain comprehensive gate-level simulation test plans for verifying ASIC functionality and timing. Analyze simulation results, identify and debug logic errors, and propose solutions.

. Work closely with design and verification engineers to validate fixes and ensure design closure.

• Develop AI-assisted Design Automation/Debug skills for various aspects of SoC development.

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.

Key job responsibilities

. Work closely with the system architects to develop world-class SOC and IP blocks, which meet power, area and performance targets.

. Define, configure and integration SoC Subsystems

. Own one or more Modem IP blocks.

. Contribute to the SoC floor planning effort

. Define and develop any necessary support logic

. Configure, instantiate and integrate 3rd party IP blocks

. Understand low power design & the impact of DFT on the blocks

. Perform initial synthesis & timing analysis

. Assist verification team in unit verification including test plan development

. Assist with debug and bring-up
