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.

We are looking for SDE II engineer with experience in supporting mission-critical applications, who are excited about building solutions that enhance automation, stability, and release processes across multiple systems. You will work closely with engineering teams to identify and address common issues, drive solutions, and improve overall release quality and reliability.

This role requires hands-on engagement, troubleshooting, and automation development. You will work within the ANCHOR team, managing release processes and automation to maintain a seamless and efficient pipeline. The team operates an on-call support rotation, and you will be responsible for maintaining release quality and pipeline health. Your work will directly impact Leo's ability to deliver high-quality, reliable releases efficiently.

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
This role sits at the intersection of test automation, CI/CD, release engineering, and operational reliability.

1. CI/CD Pipeline Ownership & Stability

• Own the daily build, test, and release pipelines end to end
• Monitor pipeline health, stability, and performance
• Diagnose and resolve pipeline failures (build, test, infra, dependency issues)
• Reduce flaky tests and nondeterministic failures
• Improve pipeline speed, reliability, and signal-to-noise ratio

2. Release Engineering & Software Delivery

• Manage software build and release activities across environments
• Track releases, validate readiness, and enforce quality gates
• Support complex, multi-stage release processes
• Ensure releases meet quality, compliance, and reliability standards
• Partner with Dev, QA, and Ops during releases and hotfixes

3. Test Automation at Scale

• Design, implement, and maintain automated test frameworks (API, integration, system, end-to-end)
• Integrate automated tests seamlessly into CI/CD pipelines
• Ensure test coverage aligns with risk, not just code coverage
• Build tooling to improve test execution efficiency and observability

4. Operational Support & Incident Response

• Respond to pipeline, release, and production-impacting issues
• Participate in triage, on-call rotations, and incident resolution
• Debug high-complexity failures across code, infrastructure, and environments
• Drive root cause analysis (RCA) and preventative fixes

5. Reliability & Continuous Improvement

• Create automated solutions to improve reliability, scalability, and efficiency
• Identify systemic issues and eliminate manual processes
• Introduce metrics, dashboards, and alerts for build/test/release health
• Champion best practices in testing, automation, and release management

6. Technical Leadership & Collaboration (Senior-Level Expectation)

• Influence architecture and design for testability and reliability
• Mentor junior engineers on automation and CI/CD practices
• Partner closely with DevOps, Platform, and Infrastructure teams
• Drive standards and long-term quality strategy

A day in the life
A Software Development Engineer works closely with development, QA, and DevOps teams to ensure the reliability and quality of daily builds, automated tests, and release pipelines. They spend much of their time monitoring CI/CD pipelines, troubleshooting build and test failures, supporting software releases, and improving test automation and operational tooling. This role is hands-on and execution-focused, with opportunities to grow toward technical ownership and leadership.
