Software Development Engineer , Ground Control Console (GC2)

Amazon Leo is Amazon"s low Earth orbit satellite network, built to deliver fast, reliable broadband to customers and communities around the world, including places traditional networks don"t reach.

As a Software Development Engineer II on the Leo Ground Control Console team, you"ll build the services, infrastructure and platform that power the web tools Leo"s engineers and operators use every day to run the constellation. That includes mission operations, network health, satellite and ground systems, and leadership views of network performance. You"ll own systems end to end, from design and infrastructure as code through production operations.

What you"ll do

• Design and build backend services and APIs that connect operator tools to data and systems across Leo"s ground and space segments, with a focus on security, reliability and low latency.
• Own the cloud infrastructure behind a shared platform used by many teams: infrastructure as code, deployment pipelines, account and access guardrails, and the shared constructs other teams build on.
• Make the platform fast and dependable at fleet scale. Find where latency and errors come from across services, fix them, and prove the improvement with data.
• Build in observability: metrics, alarms, logging and real-user monitoring, so problems surface before users report them.
• Work with engineering teams across ground and space systems to turn complex mission workflows into robust, well-designed systems.
• Raise the bar on engineering practice: design reviews, automated code review and quality checks, safe deployments, and AI-assisted development workflows that help a small team move quickly without lowering the bar.
• Support high-stakes moments such as launches, on-orbit operations and operational rehearsals, where the systems have to just work.

About you

You care about craft, reliability and the people who depend on what you build. You"re comfortable owning ambiguous problems end to end, balancing several priorities, and staying calm under pressure. You have strong software engineering fundamentals, experience building and operating distributed systems or cloud services, and you like making complex systems simpler and faster. Experience with infrastructure as code, security, performance tuning or frontend platforms is a plus. Familiarity with space or network systems is welcome but not required; you"ll learn the domain here.

About the team

The Leo Ground Control Console team owns the operational tooling used across Amazon Leo, on the ground and in orbit. We build a shared platform that is scalable, reliable, adaptable and fast, so every team at Leo can deliver tools their users rely on. We"re a small, high-ownership team that ships quickly, measures its impact, and invests in the tools and practices that make the whole organization more productive.

Key job responsibilities

Key job responsibilities

• Design, build, test and operate backend services, APIs and infrastructure for Amazon Leo"s operator and leadership tools, from design through production support.
• Own the platform"s cloud infrastructure and deployment pipelines as code, including the shared building blocks and guardrails other teams depend on.
• Measure and improve the latency, reliability and cost of services and their dependencies, and make them resilient to slow or failing systems.
• Add metrics, alarms and logging to what you ship, and use the data to prioritize improvements and show their impact.
• Partner with engineers, operators and product owners across ground and space systems to understand requirements and turn them into well-designed solutions.
• Write high-quality, well-tested code, review others" changes, and help define the team"s design standards, security practices and automated quality checks.
• Improve developer productivity through better tooling, CI/CD, test automation and AI-assisted development workflows.
• Participate in on-call and support launches, on-orbit operations and operational rehearsals.

About the team

The Ground Control Console team owns the operational tooling platform used across Project Leo to support all aspects of the mission, both on the ground and in orbit. We prioritize building a platform that is scalable, reliable, adaptable and performant in order to provide our customers with tools and support that they have come to rely on for the mission"s ongoing success.
