Facebook ASIC Engineer, Physical Design in Sunnyvale, California


Facebook's mission is to give people the power to build community and bring the world closer together. Through our family of apps and services, we're building a different kind of company that connects billions of people around the world, gives them ways to share what matters most to them, and helps bring people closer together. Whether we're creating new products or helping a small business expand its reach, people at Facebook are builders at heart. Our global teams are constantly iterating, solving problems, and working together to empower people around the world to build community and connect in meaningful ways. Together, we can help people build stronger communities - we're just getting started.


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.

Required Skills:

  1. 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.

  2. Resolve design and flow issues related to the physical design, identify potential solutions, and drive execution.

  3. 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.

  4. Define and implement schemes, including semi-custom placement and routing, to improve performance and power.

  5. Work with the RTL design team to understand partition architecture and drive physical aspects early in the design cycle.

  6. Interface with the RTL design team to drive design modifications to resolve congestion/timing issues and implement functional ECO’s.

  7. Use EDA tool-based programming and scripting techniques to automate and improve throughput and quality.

  8. Interact with tool vendors to drive tool fixes and flow improvements. Perform tool evaluations of new vendor tools and functions.

Minimum Qualifications:

  1. B.S. or M.S. degree in Electrical Engineering or equivalent similar experience.

  2. 10+ years experience in physical design and timing closure.

  3. Knowledge of RTL2GDSII flow and design tapeouts in 7nm or below process technologies.

  4. Experience with EDA tools like DC/Genus, Innovus/ICC2, Primetime, Redhawk/Voltus, or Calibre.

  5. Hands-on experience in floor planning, place & route, power and clock distribution, and timing convergence of high-frequency designs.

  6. Knowledge of geometry/process/device technology implications on physical design.

  7. Experience with large SOC designs (>20M gates) with frequencies over 1GHZ.

  8. Interpersonal, teamwork, and communication skills and experience interfacing with cross-functional teams, IP, and EDA vendors.

  9. Programming/scripting skills: TCL, Python, Perl or Shell.

Preferred Qualifications:

  1. Experience in full chip floor planning, partitioning, budgeting, and power grid planning.

  2. Experience with low power implementation, power gating, multiple voltage rails, UPF/CPF knowledge.

  3. 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.

  4. Knowledge of static timing analysis and concepts, defining timing constraints and exceptions, corners/voltage definitions.

  5. Knowledge of Circuit design, device physics, and deep sub-micron technology.

  6. Experience in the physical design of data-path intensive designs.
