About Ayar Labs

Ayar Labs is pioneering co-packaged optics (CPO) for AI infrastructure, using light instead of electricity to move data between chips. We design our TeraPHY™ optical I/O chiplets and SuperNova™ light sources in-house and, as a fabless company, partner with leading manufacturers to build them. Our Thailand team works on site at Fabrinet, our contract manufacturing partner, as the Ayar Labs technical owners of the products Fabrinet builds for us.

About the Role

Develop and run optical packaging processes, including optical coupling and receptacle attach, at our contract manufacturing partner. You own the process; partner engineers and operators execute the builds.

Key Responsibilities
  • Develop and qualify optical attach processes, including reflow and thermo-compression bonding evaluations.
  • Run packaging builds; own process documentation, travelers, and build reports.
  • Characterize optical loss, alignment tolerance, and yield; run DOEs.
  • Work with connector design teams and suppliers on interface requirements.
  • Support failure analysis and train partner operators on new processes.

Required Qualifications
  • Bachelor's degree in optics, photonics, mechanical, materials, or electrical engineering.
  • 3+ years in optical packaging or optical component assembly.
  • Experience with optical loss measurement and alignment techniques.
  • Working knowledge of DOE, SPC, and FMEA.
  • Good written and spoken English; Thai language skills a plus.

Preferred Qualifications
  • Silicon photonics or co-packaged optics experience; adhesive process experience.

Work Environment

On site at our partner's facility, including cleanroom and ESD-controlled areas; occasional off-shift support during builds. May require some early-morning or evening calls with the US site located in San Jose, CA.
