About the Role


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: We are seeking a motivated intern to support ongoing work in experimental diagnostics and analytical instrumentation. The role focuses on hands-on laboratory activities and contributes to the adaptation, improvement, and validation of custom experimental measurement systems used in electrochemical R&D.
This position is well suited for candidates who are comfortable working close to hardware, enjoy understanding measurement systems at a system level, and are interested in turning complex experimental outputs into quantitatively meaningful data.
 
  • Assist with the setup, operation, modification, and adaptation of experimental and analytical equipment
  • Contribute to improving and validating custom measurement setups to meet evolving experimental requirements.
  • Collaborate closely with engineers and scientists on experimental problem-solving and system-level improvements.
  • Perform Coreshell’s in-house battery fabrication and testing.
  • Participate in data acquisition, processing, and detailed experimental recordkeeping.
  • Identify and correct sources of measurement error, drift, or system artifacts.
  • Perform cell failure analysis through post-test cell disassembly followed by physical, compositional, and electrochemical characterization.
  • Manage inventory of chemicals and lab consumables and maintain standard operating procedures (SOPs).
  • Execute manual tasks requiring high precision and dexterity.
 
Requirements:
  • Strong interest in hands-on experimental research and instrumentation.
  • Familiarity with electrochemical characterization techniques and lithium-ion battery fabrication.
  • Demonstrated ability to modify or adapt hardware/experimental setups.
  • Familiarity with volume-based or gas-handling experimental systems (e.g., EC-MS) is a plus.
  • Experience translating physical system behavior into quantitative data using Python, MATLAB, or similar tools.
  • Ability to process experimental data and identify baseline drifts or artifacts.
  • Familiarity with chemistry lab safety protocols and commitment to organized work areas.
  • Currently pursuing or recently completed a degree in Mechanical Engineering, Chemical Engineering, or a closely related field.
