Senior Photonics Process Development Engineer

Key Responsibilities

• Lead hands-on process development for: Wire bonding (Au, Al; ball and wedge) Die bonding (epoxy, eutectic, and solder attach) Vacuum reflow soldering (AuSn, SAC, indium, etc.) Fiber splicing (fusion splicing, PM fiber alignment) Optics attach and active alignment (lenses, isolators, fiber arrays)
• Design and execute DOE experiments to improve yield, reliability, and performance
• Support the transition of processes from R&D to pilot and early-stage manufacturing
• Develop and maintain process flows, work instructions, and travelers
• Perform root-cause analysis for yield loss and reliability issues
• Collaborate with equipment vendors on tooling, fixturing, and process optimization
• Support product qualification, reliability testing, and failure analysis efforts
• Train technicians and manufacturing personnel on established processes
• Contribute to continuous improvement of process control and manufacturability

Requirements

• BS or MS in Optical Engineering, Electrical Engineering, Materials Science, Mechanical Engineering, Physics, or related field
• Typically 8+ years of relevant experience in photonics or optoelectronic process development
• 5-10 years of experience in photonics or optoelectronic process development
