• Learn and anticipate customer process needs through direct communication and data review; propose process solutions based on observations and experience
• Independently run experiments and lab simulations that replicate customer fab environments, helping guide internal development and demonstrating material advantages
• Collaborate with factory applications engineering in the design and execution of internal testing and customer demonstrations
• Build customer trust by delivering technical training and demonstrations that highlight unique capabilities and competitive advantages
• Own specific tool sets or process areas at customer accounts and be responsible for monitoring and maintaining consistent performance metrics
• Troubleshoot product integration issues and escalate complex problems with well-documented findings to internal RandD or engineering teams
• Support new product introductions by preparing qualification plans, running comparative data analyses, and providing real-time feedback to customers and product teams
• Create customer-facing documentation, including application notes, best-pra tice guidelines, and field service reports
• Train junior engineers and customer staff on product use, safety protocols, and troubleshooting procedures
• Build relationships with process engineers and line owners at customer sites to identify continuous improvement opportunities
• Contribute to cross-functional technical discussions and early-stage product design based on observed customer requirements and field challenges.
