Senior Applications Engineer

Who are we looking for?

We are looking for an experienced, insightful, and forward-thinking Sr. R&D Applications Engineer to lead application development for Active Copper, MacDermid Alpha's next-generation copper paste and sintering platform. Based at the MacDermid Alpha site in Wilmington, DE, you will leverage expertise in material science, processing and deposition methods through structured design of experiments. The end deliverable will be a documented finely tuned and optimized paste deposition process with minimal to no defects (think six sigma). Additional effort will be put forth in ensuring the paste products are capable of being used in a high-volume semiconductor/electronic manufacturing environment with minimal to no defects. As a leader, you will be responsible for identifying on-boarding new application equipment that is compatible and capable of achieving customer design and manufacturability targets. This role carries technical leadership and mentoring responsibility for the Wilmington Active Copper applications team, including junior engineers and technicians. You will define the technical path for the application development work stream, partner closely with R&D Innovation at our San Jose CA site, partner on projects with our Printed Circuit Board & IC Substrate experts at our Waterbury CT site, participate in select customer demos and applications, Application Qualification Team (Japan, China, Taiwan, S. Korea), and interact with Business Development teams across the Active Copper adoption curve.

What will you be doing?

• Application Development Leadership: Lead full development of the paste deposition process with optimized for quality and consistency, advancing product maturity from Early > Capable toward Capable > Deployed.
• Team Leadership and Mentoring: Provide technical supervision and mentoring to R&D Applications. Engineers and Applications Technicians on the Wilmington team; develop team members into subject matter experts on Active Copper application processes.
• Process Integration: Partner with the Application Qualification Team to integrate developed paste deposition processes into full board builds, including preplate, sinter, post-plate, and planarization.
• Experimental Design: Design and execute systematic studies using advanced printing, vacuum-assisted deposition, laser stencil cutting, and sinter press equipment to generate data packages that support customer qualification and scale-up.
• Customer Engagement: Act as the applications subject matter expert during customer technical reviews and troubleshooting sessions, building trust and helping customers qualify and scale Active Copper on their lines.
• Cross-Functional Collaboration: Wok with R&D Innovation, metrology, Business Development, and Product Management teams to resolve complex chemistry, process, and equipment challenges tied to Active Copper adoption.
• Metrology and Characterization: Utilize cross-section, SEM, AOI, and X-ray techniques to characterize deposit quality, board reliability, and process performance.
• Technical Communication : Create and deliver technical presentations and reports to internal partners and external customers; author technical documentation and best-practice guidelines for the application process.
• Strategic Input: Provide input into the strategic direction of the Active Copper business unit based on application development results and industry best practices.
