Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity. This is a software development engineering position on the Power System team, which builds the ground services that monitor, predict, and optimize power system performance across a constellation of LEO satellites. You will develop software that ingests satellite telemetry, runs predictive models, publishes power operational constraints to other systems, and surfaces health insights to mission operators. 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 In this role, you will contribute to building and operating production services that: * Ingest, process, and serve large volumes of on-orbit telemetry and derived power system metrics * Predict future satellite energy state using orbital parameters and activity schedules * Compute and publish per-satellite operational limits consumed by other planning systems * Monitor constellation health in real time, detect anomalies, and automate fault escalation You will write production-quality code, build APIs, develop data pipelines, create automated tests, and participate in on-call rotations. You will work in a small, fast-moving team where you'll ship code frequently and see your work directly impact satellite operations. This is a fast-paced, intellectually challenging position. You'll work alongside systems engineers, data scientists, and mission operators, translating models and algorithms into reliable, scalable services. We want individuals who are curious, ship quickly, and care about operational excellence. Everyone on the team needs to be entrepreneurial, wear many hats, and work in a highly collaborative environment. We will need to tackle problems that span a variety of domains. ## Related Videos - [Python Data Visualization @ Deepnote (w/ PyViz overview)](https://www.wearedevelopers.com/videos/113-python-data-visualization-deepnote-w-pyviz-overview) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Vectorize all the things!
