• Monitor process health using Statistical Process Control (SPC) tools and promptly report any out-of-control (OOC) process conditions to maintain manufacturing quality
• Respond to issues and incidents raised by Manufacturing Specialists by identifying, resolving, and documenting equipment and process-related problems following the Out of Control Action Plan (OCAP)
• Escalate new issues and collaborate with Process Module Engineers to conduct failure analysis and troubleshoot complex process challenges
• Maintain and update OCAP procedure documentation in coordination with Process Module Engineers to ensure compliance and continuous improvement
• Support Process Module Engineers in designing and executing Design of Experiments (DOE) to enhance process stability, uniformity, and yield
• Assist in modifying process recipe parameters as needed to optimize manufacturing outcomes
• Supervise and guide Shift Process Technicians to ensure effective execution of wafer fabrication processes and adherence to quality standards

Required competencies and certifications

• Bachelor's degree in Electrical Engineering, Chemical Engineering, Materials Science, Physics, or a related field
• Minimum 5 years of hands-on experience in wafer fabrication processes within the semiconductor laser or photonics industry
• Proficient in compound semiconductor processes and tools including Lithography, Plasma Etch, Wet Etch, Thin Film Deposition, and Metallization
• Experienced in InGaAsP epitaxy growth on InP substrates using Metal Organic Chemical Vapour Deposition (MOCVD)
• Skilled in data analysis software such as Excel, JMP, and Tibco Spotfire to interpret process data and support decision-making
• Adept in Statistical Process Control (SPC), Design of Experiments (DOE), and 8D problem-solving methodology to maintain and improve process quality

Preferred competencies and qualifications

• Familiarity with cleanroom protocols and semiconductor fabrication environments to ensure compliance with manufacturing standards
• Strong analytical, problem-solving, and communication skills to collaborate effectively across interdisciplinary teams
• Willingness to work 12-hour shifts, including night shifts, to support continuous manufacturing operations
