Teams at C12

Operate, maintain, and improve cleanroom equipment to support wafer fabrication for R&D and early production. Perform preventive maintenance, troubleshooting, vendor coordination, safety/SOP development, spare parts management, and continuous improvement to ensure uptime and quality in a startup quantum computing lab.

Own and mature engineering processes for quantum hardware development, working across R&D and engineering teams to characterize processes, analyze variability, investigate failures, improve yield and repeatability, and establish metrics, controls, validation, manufacturability, and industrialization foundations.

Develops 2.5D and 3D integration architectures and advanced packaging for quantum processors. Responsibilities include designing interconnects, interposers, TSVs, micro-bumps, hybrid bonds, chiplet interfaces, and integrating QPUs with cryogenic CMOS, RF, photonics, MEMS, and substrates. Performs electrical, electromagnetic, mechanical, and thermal simulations; defines fabrication processes; develops test vehicles; analyzes measurements; and collaborates across engineering and manufacturing teams.
