Description
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.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.
Key job responsibilities
- Partner with Battery, Electrical, Systems, Mechanical, Software, Reliability, Manufacturing, and Quality teams to collect and understand test requirements.
- Translate product and subsystem requirements into test objectives, test cases, procedures, operating conditions, and measurable pass/fail criteria.
- Develop and maintain test plans for battery packs, PCBAs, battery management electronics, and associated electrical interfaces.
- Design, build, configure, and validate test setups using power supplies, electronic loads, battery cyclers, DAQs, oscilloscopes, DMMs, environmental chambers, and other laboratory equipment.
- Develop test fixtures, harnesses, instrumentation, and basic test automation as needed to support efficient and repeatable testing.
- Lead OK2Test and test readiness activities by confirming hardware configuration, test setup, instrumentation, software, procedures, safety controls, and data collection are ready before execution.
- Execute electrical, functional, performance, environmental, characterization, and reliability testing at the battery pack and PCBA levels.
- Monitor testing, identify abnormal behavior, troubleshoot test setup and hardware issues, and drive root cause investigations when failures occur.
- Analyze test data using engineering analysis tools and scripts to identify trends, anomalies, performance margins, and potential failure mechanisms.
- Clearly distinguish product failures from test equipment, instrumentation, software, or procedural issues.
- Document test results, deviations, failures, and engineering conclusions with strong data traceability.
- Generate final test reports summarizing test configuration, methodology, results, pass/fail assessment, anomalies, conclusions, and recommended next steps.
- Present results and technical findings to engineering stakeholders and support decisions on hardware readiness, design changes, and additional testing.
- Improve test methods, automation, data analysis, and laboratory processes to increase test quality, repeatability, and efficiency.
- Up to 20% travelling nationally and/or internationally
Qualifications
- Experience developing test strategies and plans for complex hardware/software systems or systems of systems- Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, Systems Engineering, or a related technical field.
- 3+ years of experience in hardware test, validation, electrical test, battery testing, or a related engineering discipline.
- Experience with electrical laboratory equipment such as power supplies, electronic loads, oscilloscopes, DMMs, DAQs, battery cyclers, or similar instrumentation.
- Experience analyzing engineering test data and communicating technical conclusions.
- Experience troubleshooting electrical hardware, test equipment, instrumentation, or automated test systems.
- Experience documenting test procedures, results, failures, and engineering findings.
Extended Qualifications
- Experience testing lithium-ion battery packs, battery modules, cells, or battery management systems.- Experience with PCBA level functional, electrical, characterization, or environmental testing.
- Understanding of battery performance parameters including capacity, DCIR, SOC, cell balancing, thermal behavior, and protection functions.
- Experience with environmental testing including thermal cycling, thermal vacuum, vibration, shock, or reliability testing.
- Experience with Python, MATLAB, LabVIEW, or similar tools for test automation and data analysis.
- Experience performing structured root cause analysis on hardware or test system failures.
- Experience working in aerospace, automotive, energy storage, or other high-reliability hardware environments.
