Senior Epitaxy Process Engineer

Job Summary We are seeking a highly motivated and experienced Process Engineer (Senior) with strong expertise in III-V Epitaxy to drive the development and manufacturing of high performance semiconductor devices (such as lasers for AI data centers). The role centers on III-V epitaxial growth process development (MOCVD) combined with wafer fabrication, supporting both R&D and high-volume production. The candidate will play a key role in process optimization, yield improvement, and new product introduction (NPI). Key Responsibilities Lead the development, optimization, and qualification of III-V epitaxial growth processes (primarily MOCVD) for various device structures to meet R&D and production requirements. Drive continuous improvement of process quality such as: uniformity, defect density, and reproducibility. Support New Product Introduction (NPI) from design structure to manufacturable process flow. Collaborate closely with international teams on process development, troubleshooting, and technology transfer. Utilize data analytics, AI/ML tools, and statistical process control to enhance process capability and manufacturing efficiency. Perform and support advanced characterization and failure analysis Qualifications Education Master’s or PhD degree in Physics, Materials Science, Electrical Engineering, Chemical Engineering, or a related semiconductor field is preferred. Bachelor’s degree holders with strong relevant industry experience are also encouraged to apply. Experience & Technical Skills Hands-on experience in III-V epitaxial growth (MOCVD preferred) is preferred. Candidates with proven track record in developing and qualifying III-V epi processes for lasers, photodetectors, or other optoelectronic devices will be given priority. Deep understanding of epitaxial growth mechanisms, precursor chemistry, reactor dynamics, and structure design for III-V materials (e.g., GaAs, InP, GaN, or related compounds). Knowledge of semiconductor materials and device phy…
