• Own critical custom datapath and matrix multiplication accumulator blocks, driving execution from RTL-to-GDSII including synthesis, floor-planning, place and route (PNR), timing closure, and physical signoff.
• Understand math-intensive micro-architecture to perform detailed feasibility studies, analyzing performance, power, and area (PPA) tradeoffs to achieve optimal design closure.
• Develop and improve advanced physical design methodologies and customize implementation recipes, specifically optimizing PPA across complex arithmetic pipeline structures. Manage different PNR tools - synopsys fusion compiler, cadence (Innovus/Genus), PrimeTime, StarRC, Calibre, Apache Redhawk.
• Implement and execute key design phases: floor-planning, synthesis, placement, clock tree synthesis (CTS), timing closure, routing, extraction, physical verification (design rule checking (DRC)/layout versus schematic (LVS), electromigration (EM)/IR, and final signoff.
• Lead sub-chip execution and drive delivery, providing direct technical guidance and mentorship to a small team of engineers to ensure on-schedule project completion.

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.
