Battery Test Engineer, Amazon Leo

Amazon Leo is Amazons 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.

The Amazon LEO Battery Test & Validation team develops and executes test solutions that ensure battery hardware meets performance reliability and mission requirements. Our team supports battery packs and battery electronics throughout development qualification and production partnering closely with Battery Electrical Systems Mechanical Software Reliability Manufacturing and Quality Engineering teams.

As a Battery Test Engineer you will own battery pack and PCBA level testing from requirements through final test reporting. You will work cross functionally with engineering stakeholders to understand requirements translate them into test objectives and pass/fail criteria develop test plans and procedures build or configure test setups complete test readiness activities execute testing analyze results and communicate findings.
This is a hands-on engineering role requiring strong technical judgment structured troubleshooting and the ability to take ambiguous test needs and turn them into repeatable well-documented test campaigns.

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.
