Principal NPI Engineer - Sunnyvale, CA, United States
Originally posted 27 March 2026 by the employer.
Support NPI lifecycle, precision optical assembly, and ramp for Optical Circuit Switch (OCS) products.
About the role
The Principal NPI Engineer leads the development and introduction of Optical Circuit Switch (OCS) products from engineering prototypes through manufacturing ramp-up. The position focuses on optical assembly development, prototype builds, process development, and product characterization to meet performance, manufacturability, and reliability requirements.
What you'll do
- Support the NPI lifecycle for OCS products, including engineering builds, design verification, qualification, and manufacturing ramp. - Partner with cross-functional teams to incorporate design for manufacturability (DFM), design for assembly (DFA), and reliability requirements into product development. - Coordinate engineering builds and support prototype assembly, debug, and validation activities. - Develop and optimize assembly processes with work instructions and process documentation for manufacturing. - Provide engineering support to manufacturing during early production ramp and drive continuous improvement initiatives for process capability, product quality, and production efficiency.
What you'll need
- Understanding of fiber optic components and optical systems, including fiber arrays, collimators, optical alignment, and optical coupling. - Hands-on experience with precision optical assembly and alignment processes. - Experience with optical testing and characterization tools. - Knowledge of optical packaging, adhesive bonding, UV curing, and environmental sealing. - Experience supporting NPI builds and transition from development to manufacturing. - Proficiency with data analysis and reporting tools.
Nice to have
- PhD with 1 year experience in fiber optics, optical modules, or optical switching systems.
