Senior Battery Modeling Engineer for Fleet Optimization

Zipline; California (MO); On-site; USD 130,000 - 165,000; Full time

Job summary

Zipline is seeking an experienced battery-modeling engineer to own cell-level and pack-level electrochemical models. You will guide cell selection, charging decisions, and energy models used in fleet optimization, interfacing with mechanical, electrical, and systems teams.

You will develop state-estimation algorithms and validate models through EIS, HPPC, OCV studies, while working with MATLAB, Python, and other tools to impact real-world drone operations.

Qualifications

• 5+ years professional battery modeling or a PhD with 2+ years in electrochemical modeling.
• Deep knowledge of electrochemistry, heat transfer, thermodynamics, circuits, and numerical methods.
• Experience with battery characterization and validation testing (EIS, HPPC, OCV, aging).

Responsibilities

• Own cell-level models from electrochemistry to equivalent-circuit fidelity.
• Define electrochemistry roadmap, benchmark cells with internal teams and vendors.
• Design validation campaigns including EIS, HPPC, OCV, aging studies.
• Develop pack-level electro-thermal models for non-uniform operation.
• Create state-estimation and charging-limit algorithms for battery health.
• Integrate models into simulation and fleet optimization software.
