As a GaN Epitaxy Development Engineer on our Research & Development team, you'll have the opportunity to merge creativity with your technical expertise by shaping the future of technology, driving groundbreaking projects, and bringing new ideas to life. Are you in? Your Role Key responsibilities in your new role Epitaxial Growth & Recipe Development

• Design GaN epitaxial structures (e.g., buffer layers, superlattices, andHEMT structures) based on specific device performance targets
• Direct hands-on MOCVD (Metal-Organic Chemical Vapor Deposition) recipeoptimization

Process Integration & Manufacturability

• Transition new epitaxial processes from R&D into high-yield, high-volumemanufacturing
• Address manufacturability hurdles like defect density, wafer stress, andlayer uniformity

Data Analytics & Metrology

• Utilize Design of Experiments (DOE) and Statistical Process Control(SPC) to monitor and improve processes
• Analyze characterization data using techniques like SEM, TEM, AFM, andXRD to correlate material properties to final device performance

Strategic Leadership & Cross-Functional Work

• Influence long-term product technology roadmaps and advise management onmaterial and equipment investments
• Act as a mentor to junior and senior engineers, establishing technicalbest practices across the team
• Collaborate with device, process integration, and failure analysis teamsto rapidly resolve issues. Your Profile Qualifications and skills to help you succeed Education
