Job Description

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

About Retym, Inc

AI is transforming industries at an unprecedented scale - but today’s data center infrastructure wasn’t built to keep up. As AI workloads grow more complex and data volumes double every two years, connectivity - not compute - has become the bottleneck.

Retym is solving this challenge by delivering next-generation Coherent DSP solutions that provide high-performance, low-latency connectivity for AI infrastructure and data center interconnects.

We are a semiconductor company driven by innovation, bringing together a world-class team of chip designers, optical networking experts, and leading investors to rethink how data moves in the AI era. Our purpose-built DSP technology delivers:

Scalable, high-bandwidth interconnects for AI-driven data centers

Power-efficient, high-performance networking that removes bottlenecks

A coherent DSP provider that gives module makers more control and builds toward a more open, vibrant ecosystem

With hyperscalers deploying AI across multiple locations and AI infrastructure requirements rapidly evolving, Retym is building the connectivity backbone for the future of AI.

The future of AI isn’t just about compute - it’s about how we move data.

Together, we are building a novel semiconductor technology that will transform the datacenter and telecommunications industries.
