Internship Amazon Air Jobs (NOW HIRING)

Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable broadband connectivity to customers beyond the reach of existing networks. From households to small businesses, schools, hospitals, and government agencies, Amazon Leo will serve communities and organizations operating in places without dependable internet access.
Amazon Leo is seeking a Senior Software Development Engineer to design, build, and maintain the software that powers in-flight connectivity for commercial airlines. You will be a core contributor to the Leo Aviation Solution - the software platform that runs aboard aircraft, managing cabin Wi-Fi networks, satellite connectivity, over-the-air software updates, and operational services for passengers, crew, and airlines simultaneously.
This is a hands-on engineering role with immediate, high-visibility impact. The Leo Aviation Solution is early in its development, which means the decisions made now - in architecture, interfaces, and implementation approach - will shape the platform for years of production operation across a growing fleet. You will not only write production code but actively contribute to the technical direction of the system. In the near term, you may operate with significant autonomy, making forward progress on the platform's foundational software. Strong engineering judgment, clear documentation practices, and the ability to work through ambiguity are as important as implementation skill.
The platform spans a technically demanding stack: containerized software running on embedded aircraft hardware; a multi-segment cabin network managing VLAN-based traffic prioritization across passenger, crew, and airline operational services; satellite uplink quality-of-service scheduling; cryptographically validated over-the-air software deployments; and a security infrastructure designed to protect certified airborne systems.
The ideal candidate brings experience in aviation or aerospace embedded software, distributed systems, and cloud-to-edge solutions. The team is early, which means you'll contribute into the solution's architecture and technical approach. You'll work in productive ambiguity, where problems are not always clear and solutions need to be invented.
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
Design and implement core Leo Aviation Solution modules - cabin network management, software/configuration lifecycle, connectivity monitoring, observability, and operational portal - owning each from design through production deployment.
Build production-quality software for certified embedded environments, meeting DO-178C Level E standards.
Build and maintain the OTA software lifecycle pipeline - cryptographic validation, staged activation, automatic rollback, and version reporting to ground-side fleet systems.
Develop observability infrastructure - health endpoints, telemetry collection, built-in test execution, and the ground-side data pipeline for fleet monitoring.
Contribute to interface definitions and Architecture Decision Records, ensuring cross-workstream alignment before implementation.
Build and execute DO-178C-aligned tests, including unit, integration, requirements-based, and hardware-in-the-loop tests across cabin platforms.
Integrate software across multiple cabin hardware platforms, maintaining hardware abstraction layers for codebase portability.
Raise the engineering bar through code reviews, design feedback, and knowledge-sharing on aviation-grade development practices.
