Battery Modeling Engineer

The role

You will build and validate semi-empirical degradation models for fleet batteries. You will also help found and set up a cell characterization lab.

What you will do

• Build and validate semi-empirical degradation models for cells in the fleet.
• Help found and set up Base's cell characterization lab.
• Define test plans, select equipment, and stand up processes for aging data.
• Analyze fleet and device level data to understand degradation drivers.
• Validate model predictions against real-world behavior.
• Turn model outputs into tools and insights for engineering, fleet, and markets teams.
• Write production-quality Python and SQL.
• Track model history and communicate changes across the organization.

Required qualifications

• Background in Chemistry or Battery Physics or a related field such as electrochemistry, materials science, or chemical engineering.
• Hands-on experience with battery modeling, ideally semi-empirical or physics-informed degradation models for lithium-ion cells.
• Proficiency in Python and SQL (or equivalent).
• Familiarity with cell testing and characterization (cycling, HPPC, EIS, or similar).

Nice to have

• PhD in physics modeling or battery chemistry
• Experience with field or fleet data from deployed energy storage, EVs, or consumer electronics
