Job description

Optical Process Engineer

Key Responsibilities

• OCS Optical Structure Assembly & Integration:Develop and optimize the assembly processes for the complex 3D free-space optical structure of the OCS system. Ensure the precise spatial integration and mounting of core structural components, including MEMS arrays, MLA, FAU, relay lenses, and mechanical housings.
• Precision Alignment & Stress-Free Fixing:Design and implement high-precision active and passive optical alignment processes. Establish robust dispensing, UV/thermal curing, and mechanical fixing processes, strictly managing structural stress and thermal expansion to ensure optimal coupling efficiency and long-term structural stability.
• Material & Adhesive Selection:Lead the evaluation, selection, and qualification of critical materials, structural components, and optical adhesives (e.g., UV/thermal curing epoxies, index-matching materials). Ensure selected materials meet stringent requirements for CTE matching, curing shrinkage, low outgassing, and long-term reliability in free-space optical paths.
• Process Development & Prototyping:Drive the process development for OCS optical modules. Design and optimize specialized tools andfixtures for the handling, alignment, and assembly of delicate OCS optical structures.Translate opto-mechanical design requirements into executable assembly steps and create comprehensive documentation, including Standard Operating Procedures (SOPs) and process flowcharts.

Qualifications

• Bachelor’s degree or above in Optical Engineering, Mechanical Engineering, Materials Science, or a related field.
• Proven hands‑on experience in optical communication manufacturing processes, with a strong focus on complex opto‑mechanical structure assembly, micro‑optics alignment, and precision fixing techniques.
• Deep understanding of the mechanical and thermal properties of optical materials, structural metals, and optical adhesives. Familiarity with managing structural tolerances, stress relief, and thermal shifts in free‑space optical systems.
• Hands‑on experience with automated alignment equipment (e.g., 6‑axis stages), precision motion control systems, and optical measurement tools.
• Experience with the structural assembly of OCS, WSS, MEMS‑based optical devicesor optical transceivers is highly preferred. Strong ability to bridge the gap between optical design and physical realization.
