Senior Battery Engineer

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.

• Lead Formation process development for 60
  
  Ah pouch cells, translating lab-scale insights into manufacturable recipes
• Conduct Process FMEA to identify potential failure modes in the formation workflow—spanning electrolyte wetting, temperature control, current response, degassing, and cell sealing.
• Quantify process risk severity, occurrence, and detection to prioritize control actions and process improvements.
• Apply Fault Tree Analysis (FTA) to trace system-level cell performance issues (e.g., plating, voltage hysteresis drift, impedance rise) to specific process, material, or equipment causes.
• Lead cross-functional root-cause investigations integrating electrochemical, mechanical, and process data.

• Develop and execute statistically robust DOE plans to study the effects of formation variables on cell lifetime and degradation.
• Define qualification metrics including first-cycle efficiency, voltage-shift behavior, impedance evolution, and plating onset thresholds.
• Automate test data pipelines to extract diagnostic fingerprints for qualification and failure prediction.
• Identify and model key degradation pathways (Li plating, SEI/CEI growth, transition-metal dissolution, gas evolution, etc.) as a function of formation and cycling history.
• Perform electrochemical characterizations and post-mortem correlation to quantify reaction- and diffusion-limited losses.
• Establish predictive links between formation signatures and field lifetime performance using statistical reliability models
• Support design-of-experiments to isolate electrochemical vs. mechanical degradation contributions under thermal, C-rate, and voltage stress tests.

• B.S. degree or equivalent in Chemistry, Chemical Engineering, Materials Science OR an experience in a similarly relevant field with 2+ years of industrial experience.
• Previous experience in battery cell development, process development, or manufacturing environment preferred
• Able to safely work in a manufacturing setting.
• Strong verbal and written communication skills
• Self-starter with an ability to operate on his/her own initiative
• Creative problem solver and able to juggle multiple projects at any given time

• A “disabled veteran” is one of the following:
  • a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or
  • a person who was discharged or released from active duty because of a service-connected disability.
• A “recently separated veteran” means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.
• An “active duty wartime or campaign badge veteran” means a veteran who served on active duty in the U.S. military, ground, naval or air service during a…
