Lab Engineer 1, Environmental Test, Amazon Leo

Amazon LEO is Amazon’s low Earth orbit satellite broadband network. Its mission is to deliver fast, reliable internet to customers and communities around the world, and we’ve designed the system with the capacity, flexibility, and performance to serve a wide range of customers, from individual households to schools, hospitals, businesses, government agencies, and other organizations operating in locations without reliable connectivity.

The Test Equipment Engineer is responsible for the day-to-day execution of all test equipment maintenance activities across various types of automated test racks in the Space Simulation Lab. You will ensure all automated production test racks remain fully operational, properly calibrated, and ready for use by production technicians. When issues arise, you will respond quickly to escalations, providing troubleshooting support and resolving operational problems to minimize production downtime.

With your expertise in RF test equipment, calibration metrology, and maintenance program execution, you will maximize equipment availability and product quality for Amazon LEO's satellite production line.

• Plan, schedule, and coordinate preventive maintenance across all test rack populations, aligning maintenance windows with production schedules to minimize operational impact
• Maintain, troubleshoot, and improve test automation hardware supporting production testing
• Organize and track all rack calibration activities, ensuring traceability and compliance with calibration standards (ISO/IEC 17025, ANSI/NCSL Z540.3)
• Maintain accurate equipment records, configuration status, hardware documentation, and maintenance history in CMMS
• Oversee readiness of spare test racks — ensuring they are maintained, functional, and available for rapid swap-in when needed
• Troubleshoot electrical, mechanical, or software problems, working cross-functionally with manufacturing engineers, test engineers, lab technicians, and maintenance teams
• Perform root cause and corrective action (RCCA) analysis of issues in production testing and implement corrective actions to prevent recurrence
• Catalog test harness requirements, monitor inventory and life-usage of harnesses, and ensure adequate spare coverage
• Track and report KPIs (on-time completion rate, overdue work orders, equipment availability) and present status to leadership
• Develop and maintain calibration procedures and SOPs for RF test equipment
• Identify process inefficiencies and implement improvements to reduce maintenance burden and increase equipment uptime

Your primary goal is ensuring all automated production test racks remain fully operational, properly calibrated, and ready for use. Daily responsibilities include planning and coordinating preventive maintenance with schedulers, organizing and tracking all rack calibration activities, and maintaining accurate documentation and hardware configuration data in partnership with supporting engineering teams. You oversee the readiness of spare test racks, ensuring they are maintained and available for rapid swap-in when needed, and coordinate any required repairs to return equipment to operational status.

You manage consumables and spare parts inventory — RF cables, connector savers, test harnesses, and cleaning supplies — forecasting replacement needs and managing procurement timelines. When escalations come in from technicians, you respond quickly, providing troubleshooting support and resolving operational issues to minimize production downtime. You are willing to roll up your sleeves in a small, specialized team environment, and must be willing to work off-shifts and weekends as required.
