Company

hirify.global develops AI data center infrastructure and photonics technology, including 3D-stacked photonics engines for extreme-scale AI and HPC workloads.

What you will do

• Develop SystemVerilog RTL modules with DFT considerations for ASIC and IC development.
• Debug complex logic and mixed-signal simulations.
• Integrate silicon photonic communication and compute technology into digital accelerator designs.
• Collaborate with architecture, design verification, physical design, photonic, analog, and software teams to deliver high-performance, low-power designs in advanced technology nodes.
• Create module specifications and documentation covering functionality and timing.
• Manage RTL implementation, schedules, and technical risks to deliver functionally correct, performant designs.

Requirements

• Bachelor’s degree in Electrical or Computer Engineering or a related field.
• At least 5 years of ASIC design or similar high-speed chip design experience, including multiple successful tape-outs.
• Proficiency in SystemVerilog or Verilog for digital logic design.
• Experience debugging complex logic and mixed-signal simulations with industry-standard EDA tools such as Synopsys VCS, Cadence Xcelium, Questa, or equivalent mixed-signal co-simulation environments.
• Track record of delivering high-performance, low-power digital designs in advanced semiconductor process nodes.
• Capacity to comply with federally mandated U.S. export control requirements.

Nice to have
