Description

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. Core Responsibilities:: 1.Process Development & Failure Mode Mitigation Lead Formation process development for 60Ah 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. 2. Testing & Cell Qualification 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. 3. Degradation Mechanism Studies 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. Requirements: 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 Location & Benefits: San Leandro, CA. Full-time. $115,000 - 140,000 (depending on experience) annual salary with additional stock incentives dependent on experience. Dental, vision, healthcare and 401(k) benefits are included. Applications will be screened as received.

Responsibilities

The Senior Battery Engineer will lead the formation process development for pouch cells and conduct failure mode analysis to improve manufacturing workflows. Additionally, they will develop testing plans to study cell lifetime and degradation, and identify key degradation pathways.
