Epoxy Engineer

The role

This person will develop, evaluate, and optimize epoxy formulations for optical and photonic applications. They will also lead troubleshooting, support manufacturing scale-up, and act as a global technical expert for epoxy-related topics.

What you will do

• Develop, evaluate, and optimize epoxy formulations for optical and photonic applications
• Select adhesives based on optical, thermal, mechanical, and reliability requirements
• Define and validate dispensing, curing, and handling processes for production environments
• Establish process windows, material specifications, and control plans
• Lead root-cause analysis for adhesive-related failures
• Support yield improvement and defect reduction initiatives in manufacturing
• Resolve epoxy performance issues across temperature, humidity, and mechanical stress conditions
• Support NPI and production ramp activities across global manufacturing sites
• Work with equipment vendors on dispensing systems, curing ovens, and automation
• Support material qualification and reliability testing

Required qualifications

• 5–10+ years of hands-on experience with epoxy materials and adhesive processes
• Direct experience in optical, photonics, semiconductor, or precision electronics manufacturing
• Strong exposure to production troubleshooting and factory support
• Deep knowledge of epoxy chemistry, curing mechanisms, fillers, and modifiers
• Experience with optical alignment-sensitive assemblies
• Familiarity with dispensing technologies (time-pressure, auger, jetting, automated systems)
• Understanding of thermal, mechanical, and optical impacts of adhesive selection
• Ability to analyze failure modes and drive data-based decisions
• Experience in silicon photonics, fiber optics, or laser/optical modules
• Knowledge of industry standards (Telcordia, JEDEC, MIL-STD)
• Good command in English communication both verbal and written, including in-person and virtual presentation skills
• Able to train and mentor peers when needed
