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. DSP Modem Embedded Software Design Engineer, you will own critical components of the physical layer software that drives our custom satellite modem ASIC. You'll work across the full development lifecycle — from architecture and requirements through implementation, silicon bring-up, integration, and on-orbit operations.

You will operate at the boundary between hardware and software, writing performance-critical code that directly interfaces with custom DSP accelerators and manages real-time link-layer behavior for a broadband LEO constellation.

Key Responsibilities:

- Develop embedded software in assembly, C, and C++ in a real-time operating system environment for broadband satellite modem systems.
- Write real-time critical software t...
