Your mission
As a Staff Software Engineer, Battery Systems, you are responsible for all aspects of development for software relating to the battery systems, including interfacing with engineers to develop and understand requirements, modeling the battery system, architecting and writing high quality code, building tests and test infrastructure, documentation, and supporting through the software lifecycle. You will report to the Manager of Flight Software and work very closely with the Battery Team as part of a multi-functional team. As an early hire within the organization, part of your responsibility will be to lay the technological foundation for the battery control scheme, including but not limited to writing analytical battery models, developing the control architecture and writing real-time and embedded controls algorithms.
Key responsibilities include but are not limited to:
- Lead the development and prototype the Battery Management system that includes controllers and firmware to deliver the most power and energy possible while maximizing capacity retention over the life of Battery Packs.
- Lead the deployment of algorithms, firmware, and hardware that predict available power and energy, functions that ensure optimal charging, effective thermal management, and high-voltage safety monitoring while ensuring warranty and lifetime.
- Design models, define algorithms, write testing code, and evaluate the performance throughout the lifetime of the product.
- Deliver State-of-Charge, State-of-Health, State-of-Power, and State-of-Energy computations and estimations.
You will initially report to the Director of Battery and belong to the Battery team. Your place of work will be at our office located in El Segundo, CA (Los Angeles).
