If you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us! Position Summary We are seeking an experienced Senior / Principal Process Engineer – Die Bond to provide technical leadership and hands-on engineering support for high-precision optical and photonics manufacturing. This role will serve as a key technical owner for the die bond / die attach process , with responsibility for process development, characterization, qualification, technology transfer, manufacturing readiness, yield improvement, and high-volume production ramp. The ideal candidate will have strong practical experience in high-precision die bonding, preferably involving laser die-to-submount assembly , and the ability to independently troubleshoot complex process and equipment issues on the manufacturing floor. The successful candidate will work closely with R&D, Quality, Operations, Supply Chain, equipment suppliers, and Contract Manufacturers to support successful product commercialization and sustained manufacturing excellence. Key Responsibilities Process Development and Technical Ownership • Develop, characterize, optimize, qualify, and sustain high-precision die bond and die attach processes. • Own key process parameters, including placement and alignment accuracy, bonding force, bonding temperature and time, bond-line thickness, material selection, tooling, and collet • design. • Define process windows, control methods, acceptance criteria, and capability requirements for critical process characteristics. • Evaluate process, material, and equipment performance using engineering data and statistical analysis. • Identify and implement new process concepts, equipment technologies, automation solutions, and manufacturing approaches. • Provide technical leadership for complex die bond process and equipment challenges. NPI and Manufacturing Transfer • Transfer new products from R&D into Contract Manufacturing, ensuring process readiness and successful production ramp-up. • Support design-for-manufacturability activities and provide process feedback to R&D during early product development. • Plan and execute engineering builds, First Article Inspection, process characterization, CM qualification, process validation, and manufacturing readiness activities. • Support product transitions from development through qualification and high-volume manufacturing. • Provide technical support for products already transferred to manufacturing, including validation of process changes and second-level engineering support for production issues. Process Qualification and Documentation • Develop and maintain manufacturing documentation, including work instructions, process specifications, control plans, process flow documentation, and engineering change records. • Compile and evaluate test data to establish appropriate process limits, specifications, and material requirements. • Ensure process changes are properly evaluated, qualified, documented, and implemented. • Partner with Quality and Operations to ensure process controls are effectively maintained in production. Yield Improvement and Problem Solving • Analyze manufacturing data, SPC trends, yield performance, process capability, and defect data to identify improvement opportunities. • Lead root-cause investigations using structured problem-solving methods, including 8D, 5-Why, Fishbone, DOE, SPC, and fault-tree analysis . • Implement effective corrective and preventive actions and verify their effectiveness. • Drive improvements in yield, process capability, product quality, reliability, cycle time, productivity, and manufacturing stability. • Lead initiatives related to automation, cycle-time reduction, equipment optimization, and cost reduction. Cross-Functional Leadership • Lead cross-functional projects involving new manufacturing technologies, equipment, automation, materials, and process improvements. • Work closely with R&D, Quality, Operations, Supply Chain, equipment suppliers, and Contract Manufacturers to resolve technical issues and meet project milestones. • Communicate technical risks, project status, recommendations, and recovery plans to internal and external stakeholders. • Mentor junior engineers and provide technical guidance on complex manufacturing challenges. Required Qualifications • Bachelor’s degree or higher in Mechanical Engineering, Materials Engineering, Manufacturing Engineering, Electronics Engineering, Mechatronics, Physics, Applied Physics, or a related technical field. • Senior level: typically 8+ years of relevant experience in process or manufacturing engineering. • Principal level: typically 10+ years of relevant experience with demonstrated technical leadership and ownership of complex manufacturing processes. • Strong manufacturing engineering experience with optoelectronic devices, optical modules, or precision assembly. • Strong experience with New Product Introduction, process development, product qualification, and transferring products into high-volume manufacturing. • Hands-on experience developing, optimizing, and sustaining high-precision die bond or die attach processes. • Experience with laser die-to-submount assembly is strongly preferred. • Strong knowledge of SPC, process capability analysis, Cp/Cpk, DOE, statistical data analysis, and structured problem solving. • Experience working with Contract Manufacturers, equipment suppliers, and cross-functional engineering teams. • Good English communication skills, both written and verbal. • Willingness and ability to travel internationally as required. Preferred Experience • Experience with optical communication products, optical transceivers, tunable lasers, optical receivers, photonic devices, or related optoelectronic assemblies. • E…
