Job description

Amazon Leo is Amazon's low Earth orbit satellite network. 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.

Basic Qualifications

• - 3+ years of non-internship professional software development experience
• - 1+ years of designing and developing large-scale, multi-tiered, multi-threaded, embedded or distributed software applications, tools, systems, and services using: C#, C++, Java, or Perl experience
• - Bachelor's degree or foreign equivalent in Computer Science, Engineering, Mathematics, or a related field
• - Proficiency in Python or Java
• - Experience with at least one of: data pipelines, cloud services, or distributed systems
• - Familiarity with version control (Git) and software development best practices (testing, code review, CI/CD)

Preferred Qualifications

• - 3+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• - Experience with AWS services (Lambda, Step Functions, DynamoDB, Athena, Timestream, S3, or similar)
• - Experience building data pipelines that process time-series or telemetry data
• - Familiarity with monitoring and observability tools (Grafana, CloudWatch, or equivalent)
• - Experience with Python scientific computing libraries (NumPy, Pandas, SciPy)
• - Interest in spacecraft systems, power engineering, or physics-based modeling
• - Strong written communication skills and ability to document designs and operational procedures
