• Familiarity with automated assembly systems and process automation methodologies.
• Strong data analysis skills using tools such as JMP, Minitab, MATLAB, or Python.
• Ability to interpret device performance data (LIV curves, wavelength, thermal behavior) and relate it to assembly processes.

Responsibilities

• Develop, qualify, and sustain wire bonding processes for laser diode die attach and packaging (e.g., Au ball bonding, wedge bonding).
• Optimize precision soldering processes for die attach, sub-mount attach, and optical subassembly integration.
• Operate, program, and maintain Fineplacer systems for high-precision die placement, alignment, and bonding.
• Own and optimize process recipes for vacuum soldering systems and thermal processing equipment, including reflow, annealing, cure cycles, and temperature uniformity.
• Implement automation solutions to increase consistency, reduce cycle time, and improve process control.
• Create detailed manufacturing documentation: work instructions, standard operating procedures, control plans, and PFMEAs.
• Conduct root cause analysis for bonding or soldering defects and implement corrective actions.
• Collaborate with R&D to transition new laser diode designs into scalable, production-ready processes.
• Monitor SPC data, yields, and critical process parameters to identify improvement opportunities.
• Support equipment calibration, maintenance, and capability evaluations.
• Work with quality and operations to ensure devices meet electrical, optical, and reliability specifications.
