About The Position

Amazon Leo is an initiative to launch a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband connectivity to unserved and underserved communities around the world. As an Opto-Electrical Liaison Engineer on the OISL team, you will support the production and integration of high-speed optical and electronic communication hardware. This role spans optical transceivers, laser drivers, detectors, and supporting electronics—ensuring hardware is debugged, validated, and delivered with high quality and performance. A day in the life Each day begins by reviewing test data, addressing non-conformances, and aligning with quality, integration, and design teams. You’ll investigate root causes—whether optical, electrical, or mechanical—then propose and implement solutions to keep hardware on track. Hands-on work may include troubleshooting hardware, authoring rework instructions, or validating process improvements on the floor. You balance speed and rigor, ensuring fixes are well-documented and maintain design intent. Your efforts directly support the delivery of reliable, space-ready optical inter-satellite link systems. About the team The OISL team develops and delivers space-based optical inter-satellite link systems, enabling high-speed laser communication across the Leo constellation. The team focuses on precision hardware, alignment, and system reliability to meet the demanding requirements of space borne optical networks.
