Embedded Software Engineer, Optical ISL (LEO)

Amazon Inc.; Redmond (WA); On-site; USD 180,000 - 240,000; Full time

Job summary

Amazon Leo is building a low Earth orbit satellite network to deliver fast, reliable broadband beyond the reach of existing networks. As a Software Engineer on the Optical Inter-Satellite Link team, you’ll help design and implement the switching fabric that routes data across the constellation, and you’ll work on the networking stack in embedded Linux for high-speed inter-satellite links.

You’ll collaborate with hardware, optics, systems, and operations teams to deploy scalable, low-latency

Qualifications

• Experience with distributed systems and high-performance networking.
• Familiarity with embedded Linux and flight software development.
• Ability to design robust software for space-grade environments.
• Strong collaboration across hardware, software, and operations teams.

Responsibilities

• Design, implement, and enhance the switch-management software — from translating routes received from a centralized SDN controller into forwarding-table entries, to building MAC-learning and loop-prevention logic for a redundant switch topology — that enables deterministic, low-latency packet forwarding across the constellation
• Design and optimize the networking layers of flight software for optical inter-satellite link systems, spanning network device drivers and protocol implementations on embedded Linux
• Collaborate with cross-functional teams — including hardware, optics, systems, communications, and operations engineers — to integrate, test, and deploy high-speed optical communication systems and the networking stack that underpins space-based connectivity
• Build and extend operational tooling for network diagnostics and observability — including routing-table inspection, packet capture and analysis, structured logging, and metrics emission — that enables rapid fault isolation and performance trending across the satellite mesh
