Senior Software Development Engineer, Amazon Leo Optical Inter-Satellite Link

About Amazon Leo

Amazon LEO is an initiative to increase global broadband access through a constellation of satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world.

What you'll do

• 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

Required qualifications

• 5+ years of non-internship professional software development experience
• 5+ years of programming with at least one software programming language experience
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Experience as a mentor, tech lead or leading an engineering team
• Experience with a switch SDK and L2 networking protocols, including RSTP, BFD, MPLS, and ARP
• Experience developing embedded and low-level networking software systems in C/C++ or Rust

Preferred qualifications

• Experience developing embedded software for space systems, including optical communication systems, laser terminals, or high-speed serial interfaces
• Experience with ARM-based SoCs
