Embedded Software Engineer, Leo Digital RF Systems

About the Role

Amazon Leo is seeking an experienced embedded software engineer with security experience to architect and develop mission-critical firmware for satellite systems. This role involves working at the intersection of hardware and software, developing ASIC firmware including control for RF communication subsystems.

Key Responsibilities

• Lead software development for critical modules: ASIC firmware, command systems, telemetry processing, power control, hardware interfaces, and autonomous capabilities, implementing security-by-design principles.
• Design and implement robust software and firmware in Linux and real-time operating system (RTOS) environments, ensuring high reliability and security under resource constraints.
• Drive security architecture for the ASIC, involving threat modeling, identifying potential vulnerabilities, conducting security reviews, and designing defensive measures.
• Build hardware interfaces using 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, chip architects, and customers to support secure custom silicon chip and board design, from concept through secure bring-up, verification, and integration.
• Champion reliability by following best practices in secure embedded software development, including secure coding standards, code reviews, and security testing.
• Partner with test engineers to integrate security validation into manufacturing and test environments.

Requirements & Tech Stack

• Bachelor's degree in Electrical Engineering or a related field.
• Experience identifying bugs in architecture, algorithms, functionality, and performance with strong overall debugging skills.
• Experience verifying at multiple levels of logic from IP blocks to SoCs to full system testing.

Qualifications

• Master's degree in Electrical or Communications Engineering or a related field.
• Experience with formal verification techniques including abstraction and end-to-end checking.
• Experience with ARM and various DSP ISAs.
• Experience with current and upcoming RF standards in cellular (4G/5G NR), WiMAX, 802.11ad, microwave backhaul, or related broadband wireless standards.
• Experience with industry standard tools and scripting languages (Python or Perl) for automation.

Export Control Requirement

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.
