Fiber Assembly Process Engineer (hiring from Associate to Senior levels) - Milpitas, California, United States
$150,000 - $177,000 USD yearly
Originally posted 16 June 2026 by the employer.
About the role
The Fiber Assembly Process Engineer is responsible for developing assembly instrumentation for high-performance and high-throughput fiber splicing, as well as studying and addressing fiber and splice reliability at datacenter scale. This position integrates fiber engineering, opto-mechanical automation, optical assembly manufacturing, and semiconductor process development.
What you'll do
- Study and root-cause sources of fiber splice loss and loss variability. - Develop and deploy advanced fiber processing equipment in collaboration with industrial partners. - Develop measurement methodologies for validating fiber and fiber splice losses at datacenter scale. - Use optical simulation tools to model the behavior and performance of fiber-fiber interfaces across diverse fiber designs. - Assess modal properties, loss mechanisms, dispersion, coupling, and other fiber characteristics through optical modeling, experimental validation, and model closure. - Partner with optical packaging and assembly validation teams to deliver test methods evaluating the performance and reliability of fiber interfaces.
What you'll need
- MSc or PhD in photonics, optics, physics, engineering, or a related field, or equivalent industry experience. - 5+ years of experience in fiber optics, optical system development, and assembly. - Strong understanding of optical fibers along with fiber splicing and measurement equipment. - Familiarity with opto-mechanical packaging and assembly equipment. - Proficiency in Python and JMP. - Experience with mechanical and/or optical instrumentation automation and control.
Nice to have
- Familiarity with back-end semiconductor packaging.
Skills: fiber splicing, opto-mechanical automation, optical assembly manufacturing, fiber process equipment, optical simulation tools, fiber reliability
