Senior Embedded Software Engineer, Amazon Leo Digital RF Systems

Amazon Leo is Amazons low Earth orbit satellite network. Our mission is to deliver fast reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools hospitals businesses and government agencies Amazon Leo will serve people and organizations operating in locations without reliable connectivity.

Join our mission to revolutionize space technology by developing secure mission-critical software that powers our satellite constellation. Your work will directly enable communications autonomous operations and reliable performance for satellites serving customers worldwidewhile ensuring robust security from the moment they launch until their planned de-orbit.

About the Role:
Were seeking an experienced embedded software engineer with strong security expertise to architect and develop mission-critical security-hardened software for our satellite systems. Youll work at the intersection of hardware software and cybersecurity creating firmware that not only controls satellite operations but also protects against evolving threats in the space domain.


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
* Lead secure software development for critical modules including ASIC firmware commanding systems telemetry processing power control hardware interfaces and autonomous capabilities implementing security-by-design principles throughout the satellites operational lifetime
* Drive security architecture and threat modeling by identifying potential vulnerabilities conducting security reviews and designing defensive measures to protect satellite systems from cyber threats
* Design and implement robust security-hardened software and firmware in Linux and real-time operating system (RTOS) environments ensuring high reliability and security under resource constraints
* Conduct and support penetration testing to validate security controls identify weaknesses and implement remediation strategies for embedded systems
* Build secure hardware interfaces by writing software that communicates with devices and electronics using protocols including I2C I3C SPI UART USB JTAG and Ethernet with appropriate security controls and authentication mechanisms
* Collaborate closely with hardware design teams security architects and customers to support secure custom silicon chip and board design bringing new hardware from concept through secure bring-up verification and integration
* Champion security and reliability by following best practices in secure embedded software development including secure coding standards code reviews and security testing to ensure our systems meet the demanding requirements of space operations
* Optimize for secure production by partnering with test engineers to integrate security validation into manufacturing and test environments
