Senior Embedded Software Engineer, Amazon Leo Digital RF Systems

Senior Embedded Software Engineer, Amazon Leo Digital RF Systems Job ID: 3130773 | Amazon Kuiper Manufacturing Enterprises LLC Amazon Leo is Amazon’s 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 worldwide—while ensuring robust security from the moment they launch until their planned de‑orbit. About the Role: We're seeking an experienced embedded software engineer with strong security expertise to architect and develop mission‑critical, security‑hardened software for our satellite systems. You'll 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 satellite’s 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. About the team: Meaningful impact: Your code will operate in space, enabling critical communications and services while protecting vital infrastructure. Technical growth: Work with cutting‑edge technology at the intersection of highly sophisticated ASIC/SOC, hardware, software, security, and space systems. Security leadership: Shape security practices and architecture for next‑generation satellite systems. Collaborative environment: Partner with world‑class hardware engineers, security architects, systems engineers, and domain experts. Innovation culture: We value creative problem‑solving and encourage new approaches to complex security and engineering challenges. Basic Qualifications: 7+ years of non‑internship professional software development experience. 5+ years of programming with at least one software programming language. 7+ years of leading design or architecture of new and existing systems experience. Experience as a mentor, tech lead, or leading an engineering team. Knowledge of programming languages such as C/C++, Python, Java or Perl. Deep expertise in secure embedded firmware development for bare‑metal or RTOS‑based systems, with proven ability to meet real‑time, low‑power, reliability, and security requirements under hardware resource constraints. Experience with debugging tools such as GDB for testing code on FPGA or prototype chips. Experience with security‑aware software design, including threat modeling, security reviews, and vulnerability assessment. Practical knowledge of penetration testing methodologies and tools for embedded systems. Preferred Qualifications: Experience in system‑level architecture and board‑level design. Background working with security‑aware bootloaders, secure boot chains, and trusted execution environments. Practical experience using cryptography libraries (mbedTLS, OpenSSL, PKCS#11) in secure applications, including key management and secure storage. Knowledge of security standards and frameworks (e.g., Common Criteria, NIST guidelines, secure coding standards). Experience with hardware security modules (HSMs) or trusted platform modules (TPMs). Familiarity with secure communications protocols and encryption implementations. Knowledge of telecommunications or data communications systems security (routers and switches). Experience with security certifications or compliance requirements for aerospace/defense systems.
