Job Summary

Coreshells 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::

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 workflowspanning 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
