Process Development Intern
Stealth-mode Battery Startup•San Jose, CA
•$45 - $55•Onsite
About The Position
We are seeking a highly motivated Process Development Engineering Intern to help create, develop, and scale up manufacturing processes for cutting-edge lithium-ion battery cell production. You will work within a cross-functional engineering team taking new battery designs from proof-of-concept through to high-volume manufacturing. The ideal candidate takes pride in hands-on work, has a first-principles approach to problem-solving, and thrives in a demanding, fast-paced environment where you will directly contribute to the factory ramp.
Requirements
- Currently pursuing a Bachelor’s or Master’s degree in Chemical Engineering, Materials Science, Mechanical Engineering, or related field.
- Hands-on experience in a lab, workshop, or previous manufacturing internship (previous experience with lithium-ion batteries is a major plus).
- Proficiency in data analysis techniques and ability to interpret experimental data.
- Knowledge of CAD software (SolidWorks, Catia) or scripting (Python/MATLAB) for process automation.
- Exceptional problem-solving skills and a desire to work in a high-expectation, fast-paced environment.
- Ability to communicate clearly and work effectively cross-functionally with quality, production, and design teams.
Responsibilities
- Process Development & Scaling: Invent, characterize, and optimize battery manufacturing processes (e.g., electrode coating, calendering, assembly, cell assembly, formation, or testing).
- Hands-on Experimentation: Perform proof-of-concept tests to green-light new materials, methods, and equipment. Build prototypes and run pilot line experiments.
- Data Analysis: Use data analysis tools (Python, SQL, JMP, Minitab, or Tableau) to analyze process capabilities, establish SPC (Statistical Process Control) limits, and improve yield.
- Root Cause Analysis: Diagnose issues found during cell manufacturing, driving root cause identification and corrective action using structured methods (DMAIC, 5 Whys, 8D).
- Equipment Commissioning: Assist in the installation, FAT (Factory Acceptance Test), and SAT (Site Acceptance Test) of new automated manufacturing equipment.
- Documentation: Create and maintain Manufacturing Instructions (MI), PFMEAs, and Control Plans to define process standards for production teams.
