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 Frontend Implementation Engineers within our Infrastructure organization. We are looking for individuals with experience in frontend implementation from RTL to netlist, including RTL Lint, CDC analysis, timing constraints, synthesis to build efficient System on Chip (SoC) and IP for data center applications.

Required Skills:

  1. Run Logic/Physical Synthesis using advanced optimization techniques and generate optimized Gate Level Netlist for Timing, Area, Power. Debug the timing/area/congestion issues and work with RTL & Physical designers to resolve them.

  2. Perform Power Estimation at RTL and Gate Level and identify power reduction opportunities.

  3. Run Formal Verification checks between RTL and Gate level netlist and debug the aborts, inconclusive and Logic Equivalency failures.

  4. Perform RTL Lint and work with the Designers to create waivers.

  5. Perform RTL DFT Analysis and improve the DFT coverage for Stuck-at faults.

  6. Perform Flat and Hierarchical Clock Domain Crossing and work with the designers to analyze the complex clock domain crossings and signoff the CDC.

  7. Perform Flat and Hierarchical Reset Domain crossing Checks. Understand the Reset-Architecture by working with Design and FW teams and develop reset groups and the corresponding reset sequence for RDC.

  8. Develop Timing Constraints for RTL-Synthesis and PrimeTime-STA for the blocks and the top level including SOC. Analyze the Inter block timing and come up with IO budgets for the various partition blocks.

  9. Develop Power Intent Specification in UPF for the multi-vdd designs.

  10. Developing Automation scripts and Methodology for all FE-tools including (Lint, CDC, RDC, Synthesis, STA, Power).

  11. Work closely with the Design Engineers, DV Engineers, Emulation Engineers in supporting them with the handoff tasks. Interact with Physical Design Engineers and provide them with timing/congestion feedback.

Minimum Qualifications:

  1. B.S. or M.S. degree in Computer Engineering, Computer Science or Electrical Engineering

  2. Experience with RTL Synthesis and design optimization for Power, Performance, Area

  3. Knowledge of front-end and back-end ASIC tools

  4. Experience with RTL design using SystemVerilog or other HDL

  5. Experience managing multiple design releases and working with cross functional teams to support and debug timing, area, power issues

  6. Experience with EDA tools and scripting languages (Python, Tcl) used to build tools and flows for complex environments

  7. Experience with communicating across functional internal teams and vendors

Preferred Qualifications:

  1. 5+ years of experience in Design Integration and Front End Implementation

  2. Synthesis Background, Timing Constraints Development, Floorplanning and STA Experience

  3. Knowledge of RTL coding using Verilog/System Verilog

  4. Knowledge of Timing/physical libraries, SRAM Memories

  5. Experience with Power, Performance, Area Analysis and techniques for reducing power

  6. Knowledge of Low power design

  7. Experience with Clock Domain Crossing, Reset Domain Crossing, LEC

  8. Experience with Design Compiler, Spyglass, PrimeTime, Formality or equivalent tools

  9. Scripting and programming experience using Perl/Python, TCL, and Make
