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. As an R&D Maintenance Technician on the Leo DevOps Equipment Team, you’ll perform corrective and preventive maintenance on mission-critical R&D test equipment — including thermal vacuum chambers, environmental test systems, and specialized aerospace testing platforms that are foundational to Leo satellite development programs. Working semi-autonomously with minimal oversight, you’ll install and commission functional test equipment and execute full life cycle maintenance on mechanical, electrical, and control systems. You’ll troubleshoot moderate to high-complexity technical issues, evaluate equipment deficiencies, complete risk assessments, and drive corrective actions that sustain maximum uptime and performance. As a senior technician on the team, you’ll serve as a technical leader and force multiplier — setting the standard for safety and workmanship, mentoring and upskilling junior technicians, and acting as a trusted point of contact for vendors, partner teams, and site leadership. You’ll anticipate infrastructure needs, coordinate change management activities, and translate frontline insight into process improvements that raise the capability of the entire team. This role is a key contributor to the operational readiness of test infrastructure supporting current and next-generation satellite development efforts — and to building a maintenance organization that scales with the program.
