As a Manufacturing Process & Equipment Engineering Intern, you’ll help capture critical equipment knowledge, organize technical information, and support continuous improvement efforts across production environments. You’ll gain hands-on exposure to manufacturing systems, process development, equipment operation, and engineering problem-solving while contributing to projects used on the factory floor.

• Develop troubleshooting guides, process flows, setup instructions, recovery procedures, and visual work instructions used by technicians and engineers.
• Build standardized equipment documentation packages and centralized troubleshooting libraries to improve operational efficiency.
• Document process configurations, operating parameters, and common failure modes to support faster issue resolution.
• Audit and improve existing technical documentation for accuracy, usability, and completeness.
• Identify documentation gaps and create scalable systems for organizing manufacturing knowledge.
• Support troubleshooting activities and gain exposure to root-cause analysis and continuous improvement methodologies.
• Analyze process and operational data to identify trends and opportunities for improvement.

• Strong attention to detail with the ability to organize, interpret, and communicate technical information clearly.
• Curious, hands-on mindset with interest in manufacturing systems and process improvement.
• Strong written and verbal communication skills.
• Prior internship, lab, manufacturing, or data-analysis experience is a plus, but not required.
