Travel ~25% to customer sites.

Provide technical expertise for semiconductor wafer inspection products through customer demonstrations, installations, troubleshooting, rapid prototyping, and product characterization. Support sales by assessing customer requirements, developing test plans, collecting/analysing data, producing best-known methods and training materials, and publishing application results. Role requires cross-functional collaboration and travel to customer sites.

Provide on-site and remote technical support for FAST/Films semiconductor equipment: diagnose, troubleshoot, repair board- and system-level issues, prepare field reports and quotes, collaborate with installation teams, and minimize customer downtime while working independently in cleanroom environments (~50% on-site).

Provide on-site and remote technical support for Surfscan semiconductor tools: diagnose, troubleshoot, and repair board- and system-level issues; minimize customer downtime; prepare field service reports and quotes; assist installations and train other engineers; work independently and spend at least half time at customer sites/cleanrooms.

Provide field service and technical support for KLA PCB/Orbotech systems: system commissioning, breakdown repairs, preventative maintenance, customer interfacing, and detailed diagnostics of pneumatic, vacuum, electronic, and computer components. Maintain field reports and represent company values.

Develop and deploy AI/ML algorithms and software for semiconductor inspection, metrology, and process control. Build scalable model training, validation, deployment, and inference systems; optimize performance with GPU acceleration and parallel computing; collaborate across teams to integrate AI into production, cloud, and edge platforms; evaluate emerging AI technologies and deliver proof-of-concepts while maintaining software quality.

Support characterization and adoption of EBeam inspection systems: design and run experiments, collect and publish results, optimize customer processes in fabs, provide training, troubleshoot and escalate, support pre-sale and post-sale activities, and report new applications to marketing. Frequent customer site work and cross-team collaboration required.

Characterize new eBeam systems and features by designing experiments, collecting data, and publishing application notes. Support product adoption and process optimization at customer fabs, provide training, troubleshoot and escalate issues, support pre- and post-sales activities, demonstrate products, and report new applications to marketing. Frequent onsite work with customers and cross-functional teams.

Support customers and internal teams on overlay metrology (eBeam/optical) by applying metrology and process characterization expertise. Lead projects end-to-end, perform complex data and image analysis, present findings to customers, and collaborate cross-functionally. Travel domestically and internationally as needed. Requires advanced degree in Engineering or Physics.

Provide field service support for semiconductor manufacturing systems including commissioning, breakdown repairs, preventative maintenance, and customer-facing technical support. Troubleshoot RF, pneumatic, vacuum, electronic, PLC/DeviceNet and computer issues to component level, complete field reports, and recommend product/process improvements. Work autonomously in fab cleanrooms and travel frequently to customer sites.

Provide customer-facing technical support and applications development for SensArray metrology tools in semiconductor fabs. Develop application methodologies, run evaluations and demos, analyze process/equipment data, maintain tool uptime, collaborate with cross-functional teams, and produce technical content. Travel up to 40% to support customers and drive adoption, satisfaction, and revenue.
