Software Development Engineer - Amazon LEO, LEO Pop Control Plane

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.

Key job responsibilities

• Design and own the architectural direction of the Pop DataPlane traffic processing systems, balancing scalability, performance, and security tradeoffs across the full software lifecycle.
• Lead multi-engineer projects to build networking functions on AWS cloud infrastructure, establishing best practices for development, testing, and deployment processes.
• Collaborate with satellite network, ground station, and customer-facing teams to gather requirements, define interfaces, and ensure your systems integrate into the broader LEO architecture.
• Build and maintain CI/CD pipelines, automated tests, and operational dashboards to ensure system reliability and rapid delivery of new capabilities.
• Coach and mentor engineers on the team, driving a culture of high-quality code, thorough design reviews, and continuous improvement.

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.

About the team

Our networking team within Amazon Project Leo owns the software layer where customer traffic enters and exits the satellite network. As Project Leo moves toward worldwide service launch, we are focused on building reliable, high-throughput data-plane and control-plane systems that deliver connectivity to customers around the globe. We value an inclusive culture where every team member"s perspective strengthens our engineering decisions, and engineers here regularly expand their skills across networking, distributed systems, and cloud infrastructure. If you want to help connect underserved communities to the internet, this is the team to join.
