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 with or without reliable connectivity. Our Payload Integration and Testing (PIT) team validates the end-to-end network interface communication system both on the ground prior to launch and in-orbit to ensure we are providing customers a best-in‑class experience. We're the final software quality gate, ensuring what customers experience on-orbit matches our design intent.

Key job responsibilities

Design, build, and maintain test automation frameworks, test harnesses,



and orchestration software that validate the satellite network end to end

Develop automated test suites and the tooling engineers use to author, run, schedule, and debug tests across distributed HITL venues

Write and maintain the low-level interface code and device drivers that let test systems command and read back from lab hardware over protocols such as serial/UART, I2C/SPI, USB, Ethernet, and instrument-control interfaces (e.g., SCPI)

Perform device bring‑up and integration: understand hardware command sets and register maps, debug at the protocol level, and build the abstraction layers that expose hardware to higher‑level test automation

Design, build, and operate the infrastructure and networking that connects distributed hardware‑in‑the‑loop test venues to cloud services

Automate provisioning, configuration, and deployment of test environments using infrastructure‑as‑code and CI/CD pipelines

Build and own monitoring, alarming, dashboards, and observability for test orchestration systems and the infrastructure they depend on

Drive operational excellence: on‑call response, incident management, root‑cause analysis, and systemic fixes that prevent recurrence

Identify and resolve systemic reliability, scaling, and performance issues across the test stack -- automation, compute, network, and storage

Collaborate with software engineers,



applied scientists, systems engineers, and test teams to translate test and operational requirements into robust automation and infrastructure

Write clean, maintainable, well‑documented software following engineering best practices, and participate in design and code reviews

Basic Qualifications

Bachelor's degree in computer science or equivalent

Experience programming with at least one modern language such as Python, Ruby, Golang, Java, C++, C#, Rust

Experience in Linux OS and network troubleshooting, or experience in Linux and Networking protocols and experience in networking administration and troubleshooting

3+ years of professional software development experience, including building test automation, tooling, or production systems

Experience designing and building automated test frameworks, test harnesses, or test orchestration software

Experience interfacing software with physical hardware at a low level -- e.g., writing or debugging device‑control code over serial/UART, I2C/SPI, USB, GPIO, or instrument‑control protocols, and reading hardware command/register documentation

Understanding of networking fundamentals (TCP/IP, DNS, routing, firewalls) and the ability to diagnose connectivity issues

Experience building and operating production infrastructure, including automated provisioning and deployment

Preferred Qualifications

Experience with distributed systems at scale

Experience building large‑scale or distributed test automation for hardware‑in‑the‑loop, embedded, or networked systems

Experience with AWS infrastructure services (EC2, VPC, IAM, S3, CloudWatch) and infrastructure‑as‑code (CDK, C
