San Jose (on-site)

Ayar Labs is shattering AI data bottlenecks by moving data at the speed of light. As pioneers of co-packaged optics (CPO), we are using light instead of electricity to move data faster, further, and with a fraction of the energy needed to fuel the explosive growth of AI models.

Backed by industry giants like NVIDIA, AMD and Intel and manufactured in partnership with the world’s leading semiconductor ecosystem, Ayar Labs’ co-packaged optics solution is key to unleashing next‑generation AI scale‑up architectures.

• Work on path‑finding activities and advanced product & technology roadmaps.
• Participate on SSOs such as Open Compute, UEC, ESUN, Ultra Accelerator Link, OIF, and IEEE 802.3.
• Participate in technology evangelization through customer presentations, conference papers, seminar/webinars.

• MS degree in Mechanical or Electrical Engineering or equivalent
• 10+ years of industry experience
• 5+ years of experience in AI/ML, HPC and networking platforms
• AI or HPC compute chassis and rack design experience
• Experience with thermal analysis, air‑cooled or liquid cooling solutions, interconnect cabling, fiber management, rack physical design, chip packaging, power delivery, signal integrity
• Understanding of OAM, OSFP/QSFP, and PCIe cards and connector specifications
• Understanding of NRZ, PAM4, and coherent modulations
• Understanding of D2D and Ser Des links
• Familiar with relevant standard‑setting standards
• Experience with AutoCAD, Shapr3D, or similar

• Ph.D.
• Optical interconnect experience
