AI in this role

Amazon Project Leo is building a constellation of low-Earth orbit satellites to deliver low-latency, high-speed broadband connectivity to communities around the world. As a Senior Software Development Engineer on the networking team, you will architect and build the data-plane and control-plane traffic processing systems that connect the satellite network to customers. You will design these systems from the ground up as Project Leo prepares to launch worldwide service, working across the full software lifecycle from requirements through deployment and operations. This is a hands-on technical leadership role where your design decisions will directly affect how millions of people experience the internet.

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 {ADDRESS} as a refugee or granted asylum.

Key job responsibilities
- Own the architectural direction of the networking data-plane and control-plane systems, defining scalability, performance, and security tradeoffs while keeping designs simple and extensible.
- Lead multi-engineer projects to build networking functions on cloud infrastructure, establishing development, testing, and deployment best practices that the broader team adopts.
- Collaborate with satellite network, ground station, and customer-facing teams to gather requirements, define interfaces, and ensure your systems integrate into the end-to-end network architecture.
- Build and maintain CI/CD pipelines, automated tests, and operational dashboards that keep services reliable and enable rapid, incremental delivery of new capabilities.
- Coach and mentor engineers through design reviews and code reviews, raising the team's overall code quality and helping colleagues grow into larger technical responsibilities.

A day in the life
You will often start by reviewing operational metrics for the networking services your team owns, then move into design sessions with satellite network and ground station engineers to work through how new traffic flows will be processed. Afternoons typically mix hands-on coding with code reviews where you help set the quality bar. You will regularly partner with product and systems engineers to turn customer connectivity requirements into technical designs, and you will participate in on-call rotations to keep the services running smoothly.

Our networking team within Amazon Project Leo owns the software layer where customer traffic enters and exits the satellite network.
