Battery Scientist

San Leandro, CA
Full Time
Mid Level

Coreshell's metallurgical Silicon anode technology delivers high capacity, fast-charging, and superior safety. Our low-cost liquid-phase nano-coating addresses critical electrode-surface degradation issues and enables batteries with a Silicon-dominant anode that have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Our Si anode material is lower than the cost of graphite and 100% domestically sourced. We strive to transform the global automotive market by enabling low-cost and long-range EVs as a first step towards net-zero sustainability in the near future.

Position Summary
This Battery Scientist role is focused on accelerating development of Coreshell’s cutting-edge cell chemistry in cylindrical cell form factors. You’ll have the opportunity to work across the complete development effort, from materials chemistry to product testing, leveraging both internal and external partnerships to place this product in the market.


Core Responsibilities

  • Lead integration of novel cell chemistries in cylindrical cell form factors, including design refinement, validation, and implementation in manufacturing settings.
  • Perform necessary foundational work: materials screening; electrode coatings with both drawdown and slot die coaters; cell assembly; mechanical and electrochemical characterization; process and formulation refinement.
  • Ensure rapid and efficient progress using design-of-experiment, computational modeling, iterative evolution, and accelerated aging/stress-testing protocols.
  • Collaborate within the Cell Development team and cross-functionally with R&D, product, commercial, and manufacturing teams to ensure cells meet customer performance requirements and are ready-to-manufacture.
  • Characterize cells and battery materials, using both electrochemical methods & materials analytical techniques.
  • Perform cell failure analysis using both non-destructive methods and post-test cell disassembly followed by physical, compositional, and electrochemical characterization.
  • Lead FMEA efforts to identify and solve quality problems arising from material, design, and process-related factors.
Required Experience & Qualifications
  • Demonstrated excellence in battery R&D and a background in manufacturing of lithium-ion batteries are required.
  • Experience with silicon-dominant anodes preferred.
  • Knowledge of chemical laboratory and manufacturing environment safety practices.
  • Ability to excel in highly dynamic, early-stage environments; navigating ambiguity, making progress despite incomplete data, and balancing priorities to meet both immediate and longer-term goals.
  • A high degree of professionalism, excellent communication, and presentation skills are essential.
  • A Ph.D. in Chemistry, Materials Science, Engineering, or a related field, with 2+ years of industry experience.  Candidates with a Master's or Bachelor's degree and significant industry experience may also be considered.

Location & Benefits
  • Location: San Leandro, CA
  • Employment: Full-time
  • Compensation: $115,000 – $150,000 base salary (salary and equity dependent on experience)

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
