Systems Dev Engineer - Environmental Testing, Amazon Leo

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. This is a broad scoped position providing manufacturing test ownership of multiple test systems for the Leo's satellite program. You will be supporting new satellite testing early in the production ramp phase, providing critical design for test input and supporting production of the environmental testing process. As a Systems Development Engineer on the Environmental Test team, you will drive troubleshooting and continuous improvement of test systems while building on existing designs to meet the demands of production. You will develop automation strategies and implement error-proofing measures that increase test stability and system resiliency. This role sits at the intersection of hardware, software, and production operations, requiring the ability to author high-quality code, build reliable hardware, and write clear, future-proof documentation. We are looking for a candidate who thrives in a fast-paced manufacturing environment and can seamlessly bridge the gap between engineering design and production execution. Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Key job responsibilities * Experience with test automation frameworks like TestStand, Robot Framework, or similar tools for creating and managing automated test sequences. * Ability to convert test plans and hardware specifications into automated scripts that execute test cases, record results, and handle exceptions. * Experience with designing test cases for functional, performance, and stress testing in hardware systems. * Strong debugging skills for identifying issues in both the test scripts and hardware setups. * Familiarity with test equipment error logs, signal analysis, and troubleshooting hardware and software integration problems. * Understanding of hardware communication protocols (e.g., SPI, I2C, RS232, Ethernet) to interface with test equipment or devices under test (DUT). *Collaborate with network support and infrastructure management teams to optimize connectivity between test systems and manufacturing software systems * Proficiency in developing manufacturing process controls to ensure product quality and consistency, including defining key process parameters, implementing statistical process control (SPC) methods, and integrating mistake-proofing (poka-yoke) techniques. A day in the life Your responsibilities will include identifying and resolving testing issues to keep production on schedule, as well as driving efficiency improvements through automation and process changes. You will collaborate closely with manufacturing, design, thermal and electrical engineering teams to achieve these objectives. * 40% on the shop floor, working with production teams to implement new processes, review & solve key technical blockers in production, performing production development testing, etc. * 30% independent development work analyzing production and test data to identify and implement key production improvement actions, acting on quality escapes by developing and implementing new quality control measures, developing & executing to existing roadmaps for capacity increase, process simplification, etc. * 30% meeting settings, collaborating with others on topics such as new design introductions, production process change management, production solution finding reviews, etc.
