ASIC Engineer, Physical Design

Meta's silicon engineering team is building custom infrastructure silicon to power the compute demands of AI, data center, and next-generation hardware platforms. As an ASIC Engineer focused on Physical Design, you will drive the physical implementation of custom ASICs from floorplanning through tapeout, working across a full-custom silicon design flow. In this role, you will collaborate closely with RTL design, verification, and package engineering teams to deliver high-performance, power-efficient silicon that underpins Meta's infrastructure at scale. Execute physical design tasks including floorplanning, placement, clock tree synthesis, routing, and timing closure for custom ASIC designs Perform static timing analysis and work to resolve setup and hold violations across design corners and operating conditions Collaborate with RTL and logic design engineers to ensure design-for-physical-implementation guidelines are met early in the design cycle Develop and refine physical design scripts and methodologies to improve automation, quality of results, and turnaround time Conduct power analysis and implement power optimization strategies including clock gating, multi-voltage domain partitioning, and IR drop mitigation Run and interpret physical verification signoff checks including DRC, LVS, and ERC to ensure design compliance with foundry rules Partner with package and board engineers to define bump maps, power delivery networks, and IO ring constraints Contribute to the development and documentation of physical design flows, best practices, and reusable block-level methodologies Analyze and resolve congestion, signal integrity, and electromigration issues across hierarchical design blocks Currently has, or is in the process of obtaining a Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience. Degree must be completed prior to joining Meta 2+ years of experience in ASIC physical design, including hands-on work with placement, clock tree synthesis, routing, and timing closure Experience with industry-standard physical design EDA tools such as Synopsys IC Compiler, Cadence Innovus, or equivalent Experience performing static timing analysis using tools such as Synopsys PrimeTime or equivalent Experience with physical verification flows including DRC and LVS signoff using Calibre or equivalent tools Experience scripting in Tcl, Python, or shell to automate physical design tasks and flows Experience with advanced process nodes (7nm or below) and associated design rule complexity Familiarity with low-power design techniques including multi-voltage domains, power gating, and dynamic voltage and frequency scaling Experience with hierarchical physical design methodologies for large, multi-million gate ASIC designs Exposure to custom data center or infrastructure silicon design from block-level implementation through tapeout
