Sr. Battery Systems Engineer, Amazon Leo

• Key job responsibilities
• Develop, maintain, and document battery system requirements across electrical, thermal, performance, safety, reliability, lifetime, and environmental domains.
• Decompose satellite and system-level requirements into battery pack, module, BMS, cell, and test-level requirements.
• Translate requirements into measurable verification criteria, test parameters, pass/fail limits, engineering guard bands, and production acceptance limits.
• Define appropriate engineering margins considering mission conditions, degradation, manufacturing variation, measurement uncertainty, and worst-case operating conditions.
• Establish and maintain requirement-to-verification traceability, ensuring critical requirements have appropriate verification methods and acceptance criteria.
• Analyze characterization, development, qualification, reliability, lifecycle, and production test data to validate assumptions, improve models, and assess requirement maturity.
• Apply Statistical Process Control (SPC), process capability analysis, distribution analysis, and trend monitoring to understand manufacturing variation and identify emerging shifts or risks.
• Investigate outliers, specification excursions, and unexpected trends to distinguish product issues from measurement variation, process drift, or inappropriate acceptance limits.
• Periodically reassess engineering and production limits as additional data becomes available while maintaining clear separation between product requirements, engineering guard bands, and manufacturing control limits.
• Partner with Systems, Battery, Electrical, Mechanical, Test, Manufacturing, Quality, Reliability, Software, and Modeling teams to drive requirement and limit changes through technical review and configuration control.
• Maintain technical documentation, including assumptions, analyses, models, verification evidence, decisions, and change history throughout the product lifecycle.
• Bachelor's degree or above in Electrical or Mechanical Engineering, or Bachelor's degree or above in engineering, management, or technology
