Job Description:

Amazon LEO is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world. Amazon LEO will help close the digital divide by delivering fast, affordable broadband to a wide range of customers, including consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity. We are seeking an exceptional Senior Software Engineer to lead our team in building the operational backbone of a revolutionary laser communication network connecting satellites in space and ground stations on Earth. This is a high-impact leadership role where you'll drive multiple concurrent projects that directly enable network operations at unprecedented scale. The Opportunity You'll architect and deliver mission-critical tools and services that power network operations for our dynamic space-based laser link infrastructure. Working in an environment where ambiguity meets innovation, you'll transform complex, evolving requirements into elegant, scalable solutions while mentoring and leading a team of engineers to execute your vision. What You'll Build Design and develop sophisticated multi-layered services that collect real-time telemetry from our satellite constellation, analyze network topology, and intelligently correlate data to identify and resolve faults. Your systems will automatically trigger remediation runbooks, escalate issues to appropriate teams, and leverage machine learning and generative AI to detect anomalies, perform root cause analysis, and predict customer impact before it occurs. What We're Looking For You bring proven experience architecting and delivering complex, distributed systems in production environments. As a full-stack engineer, you possess both the technical depth to build clean, maintainable back-end services and the product sensibility to create intuitive, actionable visualizations that operators can trust and understand at a glance. Your meticulous attention to detail manifests in every layer of the stack—from elegant API design and robust data pipelines to thoughtful UI/UX that transforms complex telemetry into clear operational insights. You excel at breaking down ambitious technical roadmaps into actionable milestones and have a track record of successfully onboarding and elevating junior engineers. Deep expertise in distributed cloud services and infrastructure-as-code principles is essential, as is the ability to thrive in high-ownership, high-accountability environments where your decisions directly impact mission success. Why This Role Matters Your work will be the operational nervous system of our space network—enabling seamless connectivity, ensuring reliability, and pushing the boundaries of what's possible in space-based communications. If you're passionate about solving hard problems at the intersection of space technology, distributed systems, and operational excellence, we want to hear from you.
