Company

Develops the hirify.global Decode Accelerator 1, a rack-scale AI accelerator using co-designed logic, data movement, packaging, optics, and interconnect technologies.

What you will do

• Design and optimize high-density fiber-optic interconnects, including fiber-to-chip and fiber-to-package coupling, routing, multiplexing, and signal distribution.
• Drive co-packaged optics integration at package and system level while addressing connectors, fixturing, alignment, thermal interactions, and opto-mechanical constraints.
• Develop optical assembly, alignment, and test processes using Design for Manufacturing principles.
• Collaborate with foundries, OSATs, contract manufacturers, R&D consortia, and tool vendors on capability development, pilot builds, process transfer, and production ramp.
• Analyze tolerance sensitivities and yield drivers, investigate production issues, and execute validation plans for optical assemblies.
• Ensure optical systems meet requirements for reliability, serviceability, field-replaceability, and high-volume manufacturing.

Requirements

• Advanced micro-fabrication experience with deep process integration expertise.
• Experience creating or modifying complete process flows for novel optoelectronic devices.
• Background in photolithography, DRIE/RIE, thin-film deposition, wafer bonding, or wet etch.
• Experience with DOE/SPC tools such as JMP or Python and disciplined process documentation.
• B.Eng., M.Sc., Ph.D., or equivalent background in Materials Science, Electrical or Mechanical Engineering, Physics, or a related field.
• Ability to work hands-on while also handling process architecture and partner coordination in interdisciplinary environments.

Nice to have

• Familiarity with wafer-level packaging or flip-chip integration.
• Experience transferring R&D processes to external pilot or production environments.
• Working knowledge of FEM, profilometry, interferometry, L-I-V, or spectral testing.
