Principal Packaging Engineer, Optical Interfaces
Team: Product Development
Location: Santa Clara, CA
Commitment: Full-Time
Workplace Type: onsite
Salary:
About Us:
nEye.ai, a well-funded optical switch startup, is poised to revolutionize the future of data centers. nEye’s MEMS-based silicon photonics optical circuit switches (OCS) eliminate critical bottlenecks in AI processing by enabling direct optical connections among thousands of GPUs and memory units. The company's SuperSwitch is an ultra-low power consumption, high radix, compact chip-scale design, offering hyperscale data centers enhanced performance, efficiency, and scalability.
Job Overview:
This role is for a highly skilled and experienced Principal Packaging Design Engineer to lead the development of our next-generation silicon photonics packaging solutions. You will be the primary architect of our optical interfacing processes, ensuring high performance and exceptional reliability. You will own the entire process, from the collaborative design of the optical and mechanical structures to process implementation and optimization with our contract manufacturing partners.
This is a hands-on technical position requiring a deep understanding of precision optical assembly. You will work closely with our integrated circuit (IC) design, mechanical, and reliability teams to create robust, manufacturable packaging solutions. Your expertise will be vital for pushing the boundaries of fiber-to-chip coupling efficiency, mechanical stability, and long-term product reliability.
Key Responsibilities
-
Design and develop robust, high-yield processes for active and passive optical interfaces to photonic integrated circuits (PICs).
-
Specialize in using advanced methods to achieve stable and reliable fiber coupling. This includes selecting appropriate materials and controlling critical parameters.
-
Collaborate with IC and mechanical design teams to define and create structures that minimize stress, ensure thermal stability, and enhance the overall reliability of the package.
-
Act as the key technical interface with our contract manufacturing partners, coordinating process design, implementation, and characterization to ensure a smooth transition from development to high-volume production.
-
Define and manage critical process controls, alignment tolerances, and metrology methods to ensure consistent, high-performance output in a manufacturing environment.
-
Conduct in-depth analysis of assembly and packaging yield data to drive continuous process improvement.
-
Define and implement test methodologies to characterize the reliability of packaged devices under various environmental and mechanical stresses.
-
Analyze reliability data to identify potential failure modes and work with design teams to implement corrective actions.
-
Utilize your understanding of thermal, modal, and stress/strain principles to predict and mitigate reliability risks associated with packaging.
