• Knowledge of SPC, DOE, Gage studies, process control, and statistical data analysis

• Experience using JMP or similar statistical software preferred

• Strong technical problem-solving, communication, and collaboration skills

• Ability to manage multiple technical projects within a fast-paced manufacturing environment

Preferred Qualifications

• Experience developing epitaxial structures for lasers, EMLs, DMLs, photodiodes, VCSELs, or other optoelectronic devices

• Experience supporting both R&D and high-volume manufacturing

• Background leading new process development or technology transfer projects

• Experience mentoring engineers or serving as a technical lead

• Familiarity with semiconductor manufacturing and cleanroom environments

 Why This Opportunity

• Lead development of advanced InP and GaAs technologies used in AI infrastructure, optical networking, and next-generation datacenter applications

• High-impact technical leadership role with direct influence on new product development

• Opportunity to work alongside world-class experts in compound semiconductor technology

• Collaborative environment with strong interaction across Design, Product, and Manufacturing Engineering
