The engineer will direct and perform SIMS Materials Analysis workflows, including sample preparation, tool setup, data acquisition, interpretation, reporting, and method development, with a focus on quality, efficiency, and throughput. This role serves as the Subject Matter Expert (SME) for SIMS analysis, providing technical leadership to various engineering and quality organizations. Responsibilities include defining and implementing laboratory workflows, analytical procedures, quality systems, and maintenance plans. The engineer will also lead the installation, acceptance testing, qualification, and optimization of SIMS instrumentation and infrastructure, partnering with Equipment Engineering and Facilities teams for tool reliability and performance. Advanced materials characterization and failure analysis using various techniques, complex analytical investigations, root cause analyses, and technical report preparation are key duties. The role supports new product introduction, technology development, yield improvement, and cost reduction initiatives. Developing and implementing new SIMS analytical methods and sample preparation techniques for emerging technologies is also required. Continuous improvement of analytical processes, laboratory operations, and throughput is expected. Collaboration with global Coherent materials characterization teams to transfer best practices and standardize methodologies is crucial. Building relationships with internal customers, global facilities, equipment suppliers, and industry experts is part of the role. The engineer will track material and device failure modes, maintain analytical databases, and provide trend analysis. Identifying developmental opportunities for the team, creating training materials, and mentoring staff are also responsibilities. The role requires leading multiple complex projects simultaneously. Support for customer-facing technical discussions, audits, and presentations related to materials characterization and failure analysis is also expected.
