Position Overview

We are seeking a Synthesis Engineer to help define and implement our industry-leading Networking IC. If you're a highly motivated self-starter eager to solve real-world problems, this is a unique opportunity to shape the future of AI Networking. As part of the Design Group, you will be responsible for defining, specifying, architecting, executing, and productizing cutting-edge Networking devices. 

Responsibilities 

• Define and maintain the synthesis flow—including logic and physical synthesis. 

• Develop and manage synthesis design constraints (e.g., SDC). 

• Design and architect top-level and block-level floorplans for multi-chiplet systems and interposers. 

• Collaborate with micro-architects on feasibility studies and performance, power, and area (PPA) tradeoffs. 

• Work with the Design and DFT teams on scan insertion and synthesis implementation steps. 

• Partner with Design Verification to support equivalence checking and functional sign-off. 

• Assist in defining and integrating low-power optimization strategies into the synthesis flow. 

Qualifications

• Master’s or Bachelor’s degree in Electrical Engineering. 

• Minimum 15+ years of relevant experience. 

• Prior experience with multiple tapeouts in deep sub-micron nodes (7nm or below) is required. 

• Proficiency with Cadence Innovus/Genus or Synopsys Fusion Compiler. 

• Strong scripting skills in Unix shell, Perl, Python, and TCL. 

• Deep understanding of CDC/RDC flows and equivalence checking. 

• Familiarity with CAD tools and logic/physical design principles for low-power, high-performance chips. 

• Knowledge of foundation libraries, VT tradeoffs, multi-track library usage, synchronizers, and lock-up latches. 

• Exposure to datapath synthesis, memory compilers, and power optimization. 

• Knowledge of Verilog and SystemVerilog. 

• Understanding of device physics and deep sub-micron technologies. 

• Experience with EMIB architectures and chip-to-chip bridging is a plus. 

• Strong problem-solving, communication, and organizational skills. 

• Ability to work effectively in fast-paced teams under aggressive development schedules.
