Physical Design Lead, ASIC

Google; Sunnyvale (CA); On-site; USD 192,000 - 278,000; Full time

Job summary

Google is seeking a senior hardware design engineer to shape the future of AI/ML hardware acceleration. You will drive TPU architecture, verify complex digital designs, and oversee RTL-to-GDSII flows including synthesis, floorplanning, place and route (PNR), timing closure, and physical signoff.

You will mentor a small team and collaborate across Google''s AI/ML hardware initiatives. The role focuses on performance, power, and area tradeoffs in sub-7nm processes, influencing product pipelines

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent practical experience.
• 10 years of experience in physical design, including custom structured datapath implementation.
• Experience hardening dense compute units (e.g., dot-product engines, MACs, multipliers, ALUs) into high-frequency, low-power macros.
• Experience in sub-7nm process nodes (FinFET and Gate-All-Around) managing density and routing in custom datapaths.

Responsibilities

• Own critical custom datapath and matrix multiplication accumulator blocks, driving RTL-to-GDSII including synthesis, floor-planning, PNR, timing closure, and physical sign-off.
• Perform detailed feasibility studies, analyzing performance, power, and area tradeoffs to achieve design closure.
• Develop and improve advanced physical design methodologies and customize implementation recipes; manage PNR tools (Synopsys Fusion Compiler, Cadence Innovus/Genus, PrimeTime, StarRC, Calibre, Apache Redhawk).
• Execute steps: floor-planning, synthesis, placement, CTS, timing closure, routing, extraction, physical verification (DRC/LVS), EM/IR, final signoff.
• Lead sub-chip execution and mentor a small team to ensure on-schedule project completion.

Job description

In most instances, this position requires in-person interviews as part of the hiring process.

Minimum qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent practical experience.
• 10 years of experience in physical design, including custom structured datapath implementation.
• Experience hardening dense compute units (such as dot-product engines, multiplier-accumulator (MACs), multipliers, or arithmetic logic unit (ALUs) into high-frequency, low-power macros.
• Experience in sub-7nm process nodes (including FinFET and Gate-All-Around architectures), managing the physical density and routing congestion typical of custom datapaths.

Preferred qualifications

• Master's degree or PhD in Electrical Engineering, Computer Engineering or Computer Science, with focus on computer architecture.
• Experience in structured placement methodologies (e.g., relative placement, data-flow driven layout, and customized power-grid stitching for dense blocks).
• Experience with tools for logic synthesis, place and route, timing analysis, and design checks for physical and electrical quality; familiarity with tools for schematics, layout, and circuit/logic simulation.
• Experience with physical design and timing, with managing PT-to-PnR timing correlations and metal-fill impacts on dense structures.
• Expert-level scripting versatility (Tcl, Python, Perl) to build layout automation and structural constraints within standard EDA tools.
