CMM SeniorLeadPrincipal NPI Engineer (NPI PE)

Primary Duties & Responsibilities

1) Product Qualifications Design System and Implementation 60%

• Serve as the primary technical interface for Contract Manufacturing during the design transfer and New Product Introduction (NPI) phase
• Process Development: Work with CM process engineering teams to develop qualify and release assembly and test processes including die attach wire bonding optical alignment and high-speed testing.
• Build Management: Lead engineering prototype pilot and production ramp builds; coordinate material logistics fixture readiness and test software validation at CM sites
• Create and maintain all essential product documentation including Bill of Materials (BOMs) process workflows work instructions and control plans
• Analyze and resolve complex product-related issues during prototyping pilot runs and ramp-up phases
• Facilitate the smooth transition of products from NPI to volume production ensuring all processes are stable capable and documented

2) Technical Scope & Documentation-40%

• Lead the product cycle as per the PIP process. Write ADRs and PIPs for the project if it is initiated directly in CM.
• DFM & Design Collaboration: Partner with R&D and design engineering early in the development cycle to influence design for manufacturability testability and assembly (DFM/DFT/DFA) for optical transceiver products
• Yield & Quality: Establish baseline yield targets drive root cause analysis for failures during NPI phases and ensure corrective actions are implemented prior to handoff.
• Review of the product TRDs Software (including Firmware Coherent proprietary control.
• Provide subject matter expertise related on hardware design including evaluation and simulation of optical/ RF components
• Design Verification Testing and Troubleshooting.
• Documentation & Transfer: Create and manage NPI documentation including control plans FMEAs process flow diagrams and qualification reports. Lead the formal technology transfer to sustaining manufacturing engineering teams.

Education & Experience

• Masters or higher degree in optical engineering optical electronic information physics electrical or electronics engineering preferred.
• Minimum 4 years of NPI or manufacturing engineering experience in optoelectronics semiconductor packaging or high-precision electronics assembly
• Good knowledge and experience of optical modeling and simulation for communication systems. Or familiar with C PCB design CAD software FPGA MATLAB and QUANTUM programming language software and systems. Or experience with Linux Logic Analyzer Baseband Python and Verilog software and systems.
• Deep expertise in GD&T statistical analysis DOE and validation methodologies
• A profound understanding of active components including high-speed lasers and photodiodes is preferred.
• Good communication skills in both English and Thai and Chinese (bonus).

Skills

• Data analysis by JMP or Mini-tab.
• Deep understanding of optical transceiver assembly processes (die attach wire bonding lens/fiber attach active alignment) and test methodologies (BER eye diagram optical power).
• Familiar with Transceiver OSA product structure.
• Prefer Similar Product Engineer working experiences in the past.
• Adaptability Innovation Planning and Organizing Problem Solving Decision Making and Continuous Improvement Professional and Technical Knowledge and Skills Reliable and Dependable Results Oriented Teamwork.
• Proficiency in DFM/DFT methodologies process qualification (IQ/OQ/PQ) and statistical analysis (JMP/Minitab)
