Light Source Integration Engineer, Technical Leader

The application window is expected to close on 1 / 30 / 2026.

This is an onsite role and will require working out of our Carlsbad, CA office location.

What You'll Do :

Work as part of a world class photonics team on the integration of Cisco's silicon photonics into our automated, high-volume packaging line. Our high-volume packaging line uses in-house designed / developed assembly and test tools and processes that provide a unique opportunity to seek modes of improvement that span from photonic chip design to optical assembly (i.e., integration of fibers, light sources, etc.). Advanced testing methods in combination with extensive data collection allow us to gain insight into interactions between materials and processes that drive improvements in product quality and overall capability of manufacturing technologies.

This multi-disciplinary position requires an in-depth understanding of silicon photonics, optics, lasers, single-mode fiber-optics components (fiber arrays, optical multiplexers and demultiplexers, etc.), fiber-optic communications system, single-mode optical-alignment / packaging and advanced data analysis techniques (preferably using SAS jmp).

Qualified candidates are expected to be able to apply advanced problem-solving skills to uncover, root cause and drive corrective action across engineering and manufacturing organizations.

Responsibilities include :

• Lead teams in resolving yield and defectivity issues in the line related to final integration of photonic components in high volume manufacturing
• Help define / improve standards and design rules (i.e., design for manufacturing) for assembly of silicon photonics products
• Work with tool and development engineers to fundamentally understand complex interactions that arise when integrating the individual components that comprise silicon photonic based transceivers.
• Build engineering dashboards and monitors to track yields, defectivity and other quality and performances issues to direct efforts to improve optical components packaging tools / process.
• Present finding to team with clear written and verbal communications

Who You'll Work With :

You will be working with the core engineering team responsible for development of Cisco's high volume silicon photonics platform. You will be part of a dynamic technology development team that works to design processes and tools as part of Cisco's high-volume silicon photonics manufacturing platform.

Who You Are :

You are an engineer or scientist with experience in one or more of the following areas : fiber optic transceivers, optics, optical packaging and fiber optic components.
