About The Position

Amazon LEO is building a revolutionary satellite constellation to deliver high-speed broadband to underserved communities worldwide. As a Software Development Engineer II on the Security and Reliability (SAR) Software team, you'll write the most critical firmware that runs on every LEO satellite. Your Rust code will execute in space, handling everything from secure boot processes to cryptographic operations, running on custom silicon with zero tolerance for failure. This isn't your typical software role. You'll work directly with hardware, debug on real silicon, and ship firmware that must operate flawlessly for 10+ years in orbit. From implementing cryptography to managing the complete boot chain, your work will protect the security backbone of a global satellite network. Join a tight-knit team of world-class engineers where you'll own significant technical surface area and see your code launched into orbit.

• 3+ years of non-internship professional software development experience
• 2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 1+ years of software development engineer or related occupational experience
• 1+ years of designing and developing large-scale, multi-tiered, multi-threaded, embedded or distributed software applications, tools, systems, and services using: C#, C++, Java, or Perl experience
• 1+ years of Object Oriented Design experience

• Bachelor's degree in computer science or equivalent

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.

Benefits
