About The Position

Amazon Leo is seeking an experienced Power Controls Engineer to join the satellite power systems team. This role involves developing models and state estimation algorithms for satellite power systems, including solar arrays, power conversion, and energy storage. The engineer will work closely with a world-class team to build and integrate models for the satellite power system, such as battery models (equivalent-circuit, aging, physics-based) and solar array degradation models. Additionally, the role includes working on state estimation algorithms like battery state of charge, battery state of health, and state of power, which can be deployed on embedded or cloud platforms. Responsibilities encompass overall modeling & algorithm design, deployment, and test verification. The engineer will analyze large datasets to evaluate battery health over its lifespan, track model accuracy, and ensure system performance meets vehicle requirements. Development and implementation of power system fault detection and mitigation are also key aspects of this position.

Requirements

• Bachelor's degree in Electrical Engineering
• 4+ years experience in simulation, modeling, and state estimation for lithium ion battery packs.
• 2+ years experience and working knowledge of Matlab or Python to extract, process, and store information from large datasets.

Nice To Haves

• Battery management system design experience in the area of charging, state estimation, and protection for electric vehicle, drones, satellite, or launch vehicles.
• Experience developing equivalent circuit, aging or physics based models for lithium-ion battery systems.
• Experience developing degradation models for solar arrays and use event based measurements to estimation degradation.
• Experience driving requirements for power/battery algorithm design and implementation of state of charge/health/power algorithms in software (embedded or cloud).
• Excellent skill at organizing data and communicating key requirements to hardware, software, and test verification team.
• Experience in developing power system fault detection and mitigation.
