We are looking for talented and experienced VLSI Design Engineers/Micro-architects.

As an VLSI Digital Design Engineer/Micro-architect, you'll have the opportunity to design highly sophisticated, innovative new cutting edge communication systems from scratch.

Key Responsibilities for a VLSI Design Engineer:

Work closely with Algorithm and Architecture teams

  • Understand and translate high-level algorithmic requirements into efficient hardware implementations.

Learn and analyze relevant protocols and standards

  • Interpret protocol specifications (e.g., Ethernet, etc.) and apply them accurately in design.

Participate in all design stages:

  • Micro-architecture definition
  • RTL coding (using Verilog/SystemVerilog)
  • Synthesis-friendly coding and timing-aware design

Collaborate cross-functionally:

  • Verification team: For testbench development, debug support, and functional coverage closure.
  • DFT team: Ensure design is scan-insertable, supports ATPG, BIST, etc.
  • Backend/Physical design team: For floorplanning, timing closure, and routing feedback.

Participate in Design Reviews

  • Present and defend design decisions in peer and formal reviews.

Perform Synthesis and Timing Analysis

  • Generate synthesis constraints (SDC), run synthesis, and analyze timing reports.

Debug and Fix Functional/Timing Issues

  • Collaborate in post-silicon or pre-silicon debug; use waveforms, assertions, and logic analyzers.

Optimize for Area, Power, and Performance (PPA)

  • Identify bottlenecks and opportunities for improvement within RTL.

Documentation

  • Maintain clear design documentation for reusability and reference (e.g., micro-architecture specs, interface docs).

Contribute to IP/SoC Integration

  • Work on integrating design blocks into larger systems and handling system-level interfaces.

Participate in Silicon Bring-up and Validation (optional but valuable)

  • Support bring-up of first silicon and assist with post-silicon validation, if applicable.

Keep up-to-date with Industry Trends and Tools

  • Learn new EDA tools, languages, and methodologies (e.g., CDC, Linting, Formal Verification).

Requirements:

Job requirements:

  • +5 years of experience as ASIC/VLSI digital design engineer
  • Strong Verilog/System-Verilog experience
  • Familiar with simulation tools/environments, verification methodologies
  • Strong team player, solid interpersonal skills
  • Entrepreneurial can-do attitude, self-motivated, able to work independently
  • BS/MS in EE/CE from lead universities

Background in one or more of the following domains is an advantage:

  • Familiar with advanced design practices (Clock/Voltage domain crossing, Low Power Design, DFT)
  • Design DSP of oriented blocks
  • Ethernet (100G and above)
  • Scripting experience using several of the following: Python, Perl, TCL
