Software Development Engineer II, Networking, Amazon Leo

Key job responsibilities

• 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

About the team

SAR Software is a specialized team of embedded software engineers within LEO responsible for the most security-critical firmware on every satellite. We own the full trust chain from boot ROM through runtime systems, including secure boot, cryptography, OTA updates, and telemetry on custom ASIC hardware. Our stack centers on embedded Rust, FreeRTOS, ARM platforms, and hardware-backed cryptography.

The team is highly selective and deeply technical, with a strong culture of engineering rigor, thoughtful design review, and end-to-end ownership. Engineers work directly with hardware test boards, JTAG debuggers, and real silicon while solving complex challenges in secure systems and applied cryptography. From architecture through orbital deployment, every team member has meaningful influence on both the technical direction and the firmware that underpins global satellite communications.
