System Development Engineer, Amazon Leo, Amazon Leo

Amazon Leo is Amazons 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. Were the final software quality gate ensuring what customers experience on-orbit matches our design intent.

As a System Development Engineer youll design and build the test automation framework and procedures that validate our satellite network end to end -- and the full stack it runs on from the device-interface layer that drives physical hardware up through the infrastructure and operational tooling that keep our hardware-in-the-loop (HILT) test venues running reliably at scale. Youll write the automation frameworks and test harnesses that exercise the system the low-level interface code and device drivers that let those harnesses command and read back from lab hardware over protocols like serial/UART I2C/SPI USB Ethernet and instrument-control interfaces and the compute networking provisioning and observability underneath that keep it all healthy. The technical scope is broad and systems-oriented: youll build test-orchestration and automation software architect and automate cloud and on-premise infrastructure integrate and bring up lab hardware down to the register and command level and drive the operational excellence practices that keep a high-stakes 24/7 test environment reliable. If you love building test automation enjoy working at the intersection of software networking and physical hardware and want to solve unique operational challenges in the space domain this is an exceptional opportunity.

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

- Bachelors 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

- 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 CloudFormation or Terraform)
- Background building CI/CD pipelines configuration management or deployment automation from scratch
- Knowledge of orchestration systems workflow engines or event-driven architectures
- Experience writing device drivers or low-level firmware or developing against embedded/RTOS or bare-metal targets
- Familiarity with hardware debugging tools (logic analyzers oscilloscopes JTAG/protocol analyzers) and board bring-up
- Experience supporting lab test or manufacturing environments with physical hardware in the loop
- Experience with containers and virtualization (Docker Kubernetes ECS)
- Demonstrated experience with monitoring alarming and operational excellence practices
- Strong problem-solving skills with the ability to work effectively under time pressure
- Experience working in startup environments or fast-paced high-growth teams
- Passion for simplifying complex problems and building flexible maintainable systems
