Senior Battery Systems Engineer, Modeling

Irvine, CA /
Propulsion – Energy Storage /
Full Time
This is what you’ll do:
·        Lead development and execution of battery design optimization through whole system modeling
·        Develop the framework for automated analysis of vehicle drive cycles and performance requirements
·        Develop and/or modify vehicle level “plant” models to support ESS design and development
·        Collaborate with simulation teams to distill correlated simulation models into executable models for analysis
·        Script and automate test runs and data analysis for presentation to vehicle stakeholders
·        Run simulations on these models, to include analyzing their interaction with ESS models
·        Generate simulation summary data (charts, reports, etc.)
·        Use this summary data to facilitate requirements negotiation with vehicle attribute and simulation teams
·        Work with vehicle simulation teams to understand their performance and durability profiles
·        Adapt these profiles for ESS compliance
·        Collaborate with other ESS Subject Matter Experts to drive ESS requirements development

This is what you’ll need:
