Sr Systems Dev Engineer, Amazon Leo OISL

Amazon LEO is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world, helping close the digital divide for consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity.

We are seeking an exceptional Senior System Development Engineer to serve as the technical lead and senior individual contributor for our Network Operations team within the Optical Inter-Satellite Link (OISL) organization. This is a high-impact role where you will represent the entire Network Operations function of OISL — owning the strategy, tooling, automation, and operational excellence of a revolutionary laser communication network connecting thousands of satellites in space.

This is a hybrid lead and senior individual contributor role. You will own the end-to-end Network Operations strategy for OISL, including defining what tools and services need to be built, driving automation of monitoring and incident response, and ensuring operational readiness as the constellation scales. You will be the senior technical voice for OISL Network Operations, partnering across the organization to drive improvements.

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.

• Own the OISL Network Operations strategy — tooling roadmap, automation priorities, and process maturity
• Lead the Net Ops on-call program: escalation design, automated ticketing, runbooks, and incident response
• Drive operational cadence: metrics reviews, readiness assessments, and capacity planning

• Build scalable services that automate monitoring, fault detection, classification, and ticketing for the optical inter-satellite link network
• Develop data pipelines for KPI tracking, anomaly detection, and proactive issue identification
• Build observability platforms — dashboards, alerting, and real-time monitoring at scale
• Apply ML/AI for fault correlation, root cause analysis, and predictive failure detection

• Partner with hardware, software, and ground network teams to drive system reliability improvements
• Lead investigations into complex link failures and constellation-level fault patterns
• Represent Network Operations in architecture reviews and program planning

• Hands-on development of tools, services, and automation (Python, Spark SQL, cloud services)
• Design testing strategies for distributed satellite network systems
• Author technical specifications and operational documentation
• Mentor team engineers

You review the ticket queue and real-time satellite link health, spot degradation patterns, query telemetry, correlate with constellation changes, and engage and work with Hardware/Embedded Software Experts to root cause the issue. You lead cross-functional syncs on recurring failures, propose automated remediation workflows, build automated ticketing pipelines that eliminate manual triage, review teammates' code, update on-call runbooks, and identify observability gaps to close.

The OISL Network Operations team is responsible for the operational monitoring, troubleshooting, and reliability of 10,000+ optical laser links carrying customer traffic across a LEO satellite constellation. We build production-grade software services and tools to automate fault detection, classification, and…
