Job Description

We are seeking a Hardware Engineer with proven expertise in high-speed digital board design and hands-on experience with simulation tools for signal integrity (SI), power integrity (PI), and RF analysis (HFSS, CST, or similar). The role involves designing, simulating, and validating complex PCBs that meet stringent performance and reliability requirements.

Requirements

Key Responsibilities:

  • Design and develop high-speed multi-layer digital PCBs (e.g., DDR, PCIe, SerDes, high-speed serial links).
  • Perform signal integrity (SI) and power integrity (PI) simulations to validate and optimize designs.
  • Use RF and EM simulation tools (HFSS, CST, or equivalent) to analyse interconnects, vias, and structures affecting high-speed performance.
  • Collaborate with cross-functional teams (firmware, software, mechanical) to ensure seamless system integration.
  • Generate and maintain schematics (ORCAD), PCB layouts (Allegro), and design documentation.
  • Lead design reviews, root-cause analysis, prototype validation and bring-ups in the Lab.

Qualifications:

  • Bachelor’s or Master’s degree in Electrical Engineering.
  • Minimum 5 years of proven experience in high-speed digital or RF board design.
  • Strong hands-on experience with SI/PI simulation tools and RF/EM simulation (HFSS, CST, or similar).
  • Deep understanding of high-speed interfaces, clock distribution, and power delivery networks.
  • Knowledge of EMI/EMC design practices and board bring-up/debug.
  • Excellent problem-solving, communication, and teamwork skills.

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.
