Facebook is hiring ASIC Physical Design Engineers within our Infrastructure organization. We are looking for individuals with experience in backend implementation from Netlist to GDSII in low power and high-performance designs to build efficient System on Chip (SoC) and IP for data center applications.
ASIC Engineer, Physical Design Responsibilities
  • Develop and own physical design implementation of multi-hierarchy low-power and high-performance designs, including physical-aware logic synthesis, floorplan, place and route, clock tree synthesis, static timing analysis, IR drop, EM, and physical verification in advanced technology nodes.
  • Resolve design and flow issues related to the physical design, identify potential solutions, and drive execution.
  • Deliver physical design of an end-to-end IP or integration of ASIC/SoC design and point out lower power and higher performance trade-offs.
  • Define and implement schemes, including semi-custom placement and routing, to improve performance and power.
  • Work with the RTL design team to understand partition architecture and drive physical aspects early in the design cycle.
  • Interface with the RTL design team to drive design modifications to resolve congestion/timing issues and implement functional ECO’s.
  • Use EDA tool-based programming and scripting techniques to automate and improve throughput and quality.
  • Interact with tool vendors to drive tool fixes and flow improvements. Perform tool evaluations of new vendor tools and functions.
Minimum Qualifications
  • Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience.
  • 5+ years of experience in interpersonal, teamwork, and communication skills and experience interfacing with cross-functional teams, IP, and EDA vendors.
  • Experience in physical design and timing closure.
  • Knowledge of RTL2GDSII flow and design tape-outs in 7nm or below process technologies.
  • Experience with EDA tools like DC/Genus, Innovus/ICC2, Primetime, Redhawk/Voltus, or Calibre.
  • Hands-on experience in floor planning, place & route, power and clock distribution, and timing convergence of high-frequency designs.
  • Knowledge of geometry/process/device technology implications on physical design.
  • Experience with large SOC designs (>20M gates) with frequencies over 1GHZ.
  • Programming/scripting skills: TCL, Python, Perl or Shell.
Preferred Qualifications
  • Experience in full chip floor planning, partitioning, budgeting, and power grid planning.
  • Experience with low power implementation, power gating, multiple voltage rails, UPF/CPF knowledge.
  • Experience in planning, implementing, and analyzing high-speed clock distribution networks. Experience with alternate strategies for clock distribution, including standard trees, mesh, H-Tree, and clock power reduction techniques.
  • Knowledge of static timing analysis and concepts, defining timing constraints and exceptions, corners/voltage definitions.
  • Knowledge of Circuit design, device physics, and deep sub-micron technology.
  • Experience in the physical design of data-path intensive designs.
  • Experience in the 3D-IC technology, methodology, and advanced packaging.
  • Experience in validating Power Distribution Network (PDN), IR/EM, Thermals for 3D-IC.
