Sr. Battery Systems 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 team develops battery systems that power Amazons Low Earth Orbit satellite constellation. Our team works across battery design systems engineering modeling test and validation manufacturing reliability quality and production to deliver safe reliable and high-performance battery systems for space applications.

As a Sr. Battery Systems Engineer you will own the development and maturation of battery requirements verification criteria and acceptance limits from early design through production. You will connect system requirements battery physics engineering analysis test results and manufacturing data to establish technically defensible requirements and pass/fail criteria.

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
- 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.
- Establish the technical rationale for requirements and limits using battery models simulation tolerance analysis Monte Carlo methods measurement uncertainty component specifications characterization data and empirical test results.
- 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.
