Join a hardware startup in Silicon Valley as a Silicon PDV Engineer to reimagine silicon and create Risc-V based computing platforms. You will develop PDV methodology and infrastructure for large SoCs, perform full chip integration and physical verification checks, and guide implementation teams for early convergence. Responsibilities include interfacing with design teams, defining padring and bump map design with package and floorplan teams, and integrating foundry PDK data with the technology team. The role requires a deep understanding of deep sub-micron process nodes, hands-on experience with closure and tapeout of large hierarchical designs, and proficiency with physical verification tools like Siemens Calibre.
