Senior Fiber Assembly Process Engineer

Originally posted 9 November 2026 by the employer.

About the role

The Senior Fiber Assembly Process Engineer develops advanced assembly instrumentation for high-performance and high-throughput fiber splicing, while studying and addressing fiber and splice reliability at datacenter scale. This role combines 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 advanced measurement methodologies for validating fiber and fiber splice losses at datacenter scale.
• Use optical simulation tools to model behavior and performance of fiber-fiber interfaces across a wide range of advanced 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 and 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, optical assembly, photonics, packaging, opto-mechanical
