Sr. Embedded Software Engineer, Amazon Leo OISL Star Tracker

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.

We are seeking a Senior Software Development Engineer to help drive design and implementation of software systems that control, monitor, and manage Star Tracker flight hardware, including real-time device control, remote management, Linux integration, software build systems and release validation testing.

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, develop, and optimize highly reliable flight software for Star Tracker flight systems, spanning low-level device drivers and real-time control loops to high-level autonomous behaviors, fault management, and AI/ML-driven decision-making that target Linux environments
• Architect and implement fault-tolerant, redundant software systems that keep systems operational with continuous uptime across a constellation of satellites, including health monitoring and autonomous recovery without ground intervention
• Build and maintain robust test, validation, and simulation infrastructure, from hardware-in-the-loop testbeds and software-in-the-loop virtualizations to automated regression suites
• Own the full lifecycle of embedded software delivery - from requirements decomposition and architecture design through implementation, code review, integration, deployment, and long-term maintenance of software running on satellites in orbit
• Collaborate deeply with cross-functional teams spanning hardware, systems, communications, manufacturing and operations engineers to design, integrate, test, and deploy high-speed optical communication systems that push the boundaries of space-based networking
• Develop and refine autonomous operational behaviors that enable satellites to independently recover and adapt to changing conditions, and respond to anomalies
• Drive continuous improvement of deployment and over-the-air (OTA) update processes, ensuring new capabilities and fixes can be safely and reliably delivered to hundreds of satellites on orbit with minimal operational risk

A day in the life

As a Senior Software Engineer on the OISL Star Tracker team, you won"t just write code - you"ll see it in action. Your software will control and monitor critical sensor hardware operating on hundreds of real satellites in orbit, and you"ll be there for every stage of the journey: from early design and on-the-ground verification to watching your code operate in-orbit and see the stars.

About the team

You will join a multi-disciplinary team of top-notch engineers whose work spans an unusually wide aperture: embedded flight software running on satellites in orbit, cloud-based systems powering mission and network operations, automation frameworks that keep a growing constellation healthy, and AI-driven capabilities that make our devices smarter with every orbit. We collaborate closely with optical, electrical, firmware, manufacturing, and operations teams - and with partner organizations including Mission Operations - to deliver one of the most advanced optical communication systems ever built.

We are looking for a senior software engineer who combines deep technical and analytical capabilities with a demonstrated ability to get the right things done quickly and effectively, and someone who thrives at the intersection of hardware and software, space and ground, autonomy and operations.
