Lightmatter Sr/Staff Digital Design Engineer at Lightmatter responsible for developing RTL modules and integrating silicon photonic technology into digital accelerator design. Collaborates with cross-functional teams to deliver high-performance ASIC designs.

Responsibilities

Develop RTL (i.e. system Verilog) modules with DFT considerations for IC development
Debug complex logic and mixed signal simulations
Understand and integrate silicon photonic communication and compute technology into digital accelerator design
Actively work with Architecture, Design Verification, Physical Design, Photonic, Analog and Software teams to realize high performance, low power designs in advanced technology nodes
Create design specifications and documentation to facilitate collaboration with partner teams
Generate documentation for modules, including functionality and timing
Manage RTL implementation to achieve functionally correct, performant designs within project schedules by identifying, communicating and mitigating risks.

Qualification

Knowledge of processor designExposure to silicon photonics (SiPh)Strong scripting skills in Python

Required

Bachelor’s degree in Electrical or Computer Engineering (or related fields)
At least 5 years of experience in ASIC design or a similar high-speed chip design with multiple successful tape outs
Proficiency in SystemVerilog or Verilog for digital logic design
Proven experience debugging complex logic and mixed-signal simulations using industry-standard EDA tools (e.g., Synopsys VCS, Cadence Xcelium, Questa, or equivalent mixed-signal co-simulation environments)
Demonstrated track record of delivering high-performance, low-power digital designs in advanced semiconductor process nodes

Preferred

Master's degree in Electrical or Computer Engineering (or related fields)
Experience in communication protocols (e.g. PCIe)
Knowledge of processor design, accelerators, and/or memory hierarchies
Exposure to silicon photonics (SiPh), optical compute/interconnect architectures, or electro-optic interface integration.
Strong scripting skills in Python, Perl, Tcl, or Bash to automate simulation and design workflows.
Experience interfacing digital logic directly with analog mixed-signal (AMS) IP (e.g., SerDes, ADCs/DACs, optical transceivers)
