Primary Duties & Responsibilities

Improve and maintain the manufacturing processes used to make semiconductor chips and optical (photonics) components. The goal is to make sure products are made accurately, consistently, and at the lowest reasonable cost. Identify problems in production, figure out what’s causing them, and fix them so fewer defects occur and overall product quality improves. Help move new technologies from research and development into full-scale production. Work closely with teams such as design, quality, equipment, and supply chain to solve manufacturing issues and support the launch of new products. Make sure proper procedures and documentation are in place and that manufacturing follows quality and ISO standards. Use specialized manufacturing machines, laser and optical equipment, inspection and measurement tools, and data analysis software to monitor performance and improve processes. Work with internal production systems to track manufacturing activity and ensure everything runs smoothly and reliably.

Education & Experience

  • 5 years of experience with Automation of bar stacking for laser facet coating or related. Requires skills and experience to involve: 
  • Strong understanding of semiconductor, photonics, and optoelectronic laser manufacturing processes, materials, and cleanroom fabrication environments.
  • Specialized experience in high-volume BGA manufacturing, including automated assembly processes, reflow operations, inspection systems, and tooling used for substrate, die, and package integration.
  • Experience working with complex, high-volume manufacturing tools used for precision pick and place components, including the ability to troubleshoot line-down situations that directly impact yield and production output.
  • Knowledge of process improvement methodologies DOE, SPC (including SPC rules), and FMEA.
