About the Role

As a Software Development Engineer II on the Security and Reliability (SAR) Software team at Amazon LEO, you will develop critical firmware for a satellite constellation aimed at providing high-speed broadband. Your role involves writing embedded Rust software, debugging hardware-software integration issues, and ensuring the reliability of systems that operate in space.

What You'll Do

Develop low-level embedded Rust software for satellite platforms, interfacing directly with custom hardware in RTOS and bare-metal systems.
Develop and maintain secure boot architectures and cryptographic implementations, including bootrom, bootloader chains, provisioning, hardware Root of Trust integration, and cryptography protocols.
Provide meaningful code review feedback to team members including senior engineers, ensuring high-quality software delivery across the full development lifecycle from design through deployment and maintenance.
Debug complex hardware-software integration issues using JTAG debuggers, interpreting logs, and working directly with custom ASIC designs, datasheets, and real hardware test boards.
Lead operational excellence initiatives for space-based systems, identifying root causes of issues, implementing permanent fixes, and maintaining reliability standards for firmware running on thousands of satellites.

Who You Are

You are a highly skilled engineer with a strong background in embedded systems and a passion for working with hardware. You thrive in a collaborative environment and are committed to delivering high-quality software that meets rigorous standards.

Basic Qualifications

3+ years of non-internship professional software development experience.
2+ years of non-internship design or architecture experience of new and existing systems.
1+ years of software development experience in Rust.

Export Control Requirement

Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum.
