Staff Battery Engineer, Battery Performance

Who You Are

As a Battery Cell Engineer on the Battery Performance team, you will leverage your expertise to design cutting-edge batteries featuring Sila’s next-generation anode material for a variety of customer applications. You possess demonstrated hands-on expertise in the comprehensive performance evaluation of battery components (including electrolytes, anodes, cathodes, foils, and separators) and have a proven ability to integrate novel components and innovations to optimize GED, cycle life, and safety tradeoffs. Your proficiency extends to supporting stacked pouch and cylindrical prototype builds, conducting thorough failure analysis, and leveraging advanced data analysis, statistical methods, and modeling to inform design iterations and solve complex challenges.

Responsibilities and Duties

• Develop and execute comprehensive test plans for multilayer and cylindrical cells, from initial novel component integration and validation through full cell qualification, ensuring rigorous data collection for analysis.
• Apply advanced data analysis, statistical methods, and modeling techniques to interpret test results, predict performance, and inform design iterations.
• Perform thorough failure analysis on prototype cells and customer qualification units to identify root causes.
• Support the successful execution of internal and external development programs by designing and refining cell prototyping processes.
• Champion our company’s vision to actively develop and integrate novel testing capabilities and methodologies at the material, electrode, and cell levels to enhance performance evaluation and accelerate learning cycles.
• Effectively communicate complex ideas, strategic plans, and critical results externally to partners and internally across Sila’s diverse teams.

Knowledge and Skill Requirements

• Solid understanding of battery performance and failure mechanisms, including electrolyte degradation, material and cell-level swell, and Li plating.
• Solid experience with characterization and integration of novel battery components.
• Experience with data and modeling.
• Experience with cell prototyping.
• Ability to carefully plan and implement multiple projects simultaneously
• B.S. in engineering or science and 8+ years of experience (fewer for candidates with an advanced degree), or related experience.

Physical Demands and Working Conditions

• Wear personal protective equipment including, but not limited to, a lab coat, gloves, safety glasses, and steel toe safety shoes
• Operate a computer and other office equipment, such as a laptop, copier/printer, etc in a fixed location
• Move long distances (such as from building to building) and be stationary for extended periods of time
• (As needed) Pass a respirator fit test and be able to wear respiratory protection

The starting base pay for this role is between $151,000 and $191,000 at the time of posting. The actual base pay depends on many factors, such as education, experience, and skills. Base pay is only one part of Sila’s competitive Total Rewards package that can include benefits, perks, and equity. The base pay range is subject to change and may be modified in the future. #LI-Onsite #LI-PL1
