About the Job

Requirements

  • A bachelor's degree in Electrical or Computer Engineering, or a related field, is required.
  • At least 5 years of experience in ASIC design or similar high-speed chip design, including multiple successful tape-outs, is required.
  • Proficiency in SystemVerilog or Verilog for digital logic design is required.
  • Experience debugging complex logic and mixed-signal simulations using industry-standard EDA tools such as Synopsys VCS, Cadence Xcelium, Questa, or equivalent mixed-signal co-simulation environments is required.
  • A demonstrated track record of delivering high-performance, low-power digital designs in advanced semiconductor process nodes is required.

Responsibilities

  • Develop RTL modules, including SystemVerilog modules, with design-for-test considerations for integrated-circuit development.
  • Debug complex logic and mixed-signal simulations.
  • Understand and integrate silicon photonic communication and compute technology into digital accelerator design.
  • 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 module documentation covering functionality and timing.
  • Manage RTL implementation to achieve functionally correct, performant designs within project schedules by identifying, communicating, and mitigating risks.

Desired Qualifications

  • A master's degree in Electrical or Computer Engineering, or a related field, is preferred.
  • Experience with communication protocols such as PCIe is preferred.
  • Knowledge of processor design, accelerators, and/or memory hierarchies is preferred.
  • Exposure to silicon photonics, optical compute/interconnect architectures, or electro-optic interface integration is preferred.
  • Strong scripting skills in Python, Perl, Tcl, or Bash to automate simulation and design workflows are preferred.
  • Experience interfacing digital logic directly with analog mixed-signal IP such as SerDes, ADCs/DACs, or optical transceivers is preferred.

About the Company

Lightmatter

Photonic computing hardware for AI acceleration

Lightmatter develops photonic computing hardware that accelerates AI workloads using light-based processors. Its photonic supercomputers run AI tasks faster and use far less energy (about 10x faster and 90% less energy) than traditional electronic systems. The company differentiates itself by focusing on electro-photonic systems and practical AI acceleration for AI and autonomous vehicle workloads, working with universities and selling hardware, software licenses, and partnerships. Its goal is to bring scalable photonic computing to market so AI and self-driving applications can run faster, more efficiently, and at larger scale.
