Senior Engineer, Alignment

Position Overview

The incumbent will involve in the development and optimization of optical alignment processes for photonic devices and optical communication products, driving improvements in yield, process stability, and manufacturing efficiency while supporting technology transfer into high-volume production.

Key Responsibilities

• Develop, optimize, and support active and passive alignment processes for photonic devices, including optical engines, transceivers, and silicon photonics assemblies.
• Improve optical coupling efficiency, alignment stability, and process repeatability across high-volume production environments.
• Perform detailed analysis and optimization of alignment processes involving lenses, FAUs (Fiber Array Units), and silicon photonics chip coupling.
• Drive improvements in throughput (UPH), yield, and process robustness through systematic experimentation and data analysis.
• Troubleshoot and resolve complex issues related to optical power variation, misalignment drift, curing effects, and mechanical/thermal stability impacts on alignment.
• Support process transfer from development/NPI to scalable manufacturing, ensuring stability and repeatability.
• Collaborate closely with cross-functional teams on photonic integration, device packaging, and optical performance validation.
• Contribute to development of next-generation alignment strategies for high-speed optical communication systems (100G–1.6T class architectures).
• Provide technical support and training related to alignment processes and optical assembly best practices.

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Mechanical Engineering, Physics, Photonics, or related field.
• 8+ years of experience in photonic device alignment, optical assembly processes, or silicon photonics integration.
• Strong hands-on experience in active alignment and precision optical coupling processes.
• Deep understanding of optical coupling principles (edge coupling, free-space coupling, grating coupling, fiber-to-chip alignment).
• Experience optimizing yield, stability, and throughput in optical assembly processes.
• Strong analytical skills with ability to debug and resolve complex optical performance issues.
• Experience working in high-speed optical communication device environments (e.g., 400G / 800G / 1.6T class systems).
