About Neurophos

The demand for new data centers and AI compute is rapidly outpacing the planet's energy capacity. Digital solutions are hitting a power wall as we approach the physical limits of traditional silicon. Conquering this bottleneck means rethinking the fundamental architecture of inference compute. The industry's current path can't meet the need, so we're taking a different approach.

Instead of traditional electronic circuits, we use silicon photonics and an active, programmable metasurface to perform matrix multiplications at the speed of light. Our optical cells are 10,000x smaller than traditional photonic components, enabling unprecedented density. By using photonics instead of electricity, our chips become more efficient as they scale. This architecture will deliver up to 100 times the energy efficiency of existing solutions while significantly improving performance for large-scale AI inference.

We’ve assembled a world-class team of industry veterans and recently raised a $110M Series A led by Gates Frontier. Participants include M12 (Microsoft’s Venture Fund), Carbon Direct Capital, Aramco Ventures, Bosch Ventures, Tectonic Ventures, Space Capital, and others.

Location: Austin, TX or Sunnyvale, CA. Full-time onsite position.

Reports To: Director of Digital Design

FLSA Status: Exempt

Position Overview

Key Responsibilities

• Own verification methodology and testbench architecture, built on UVM with a strong
  
  

emphasis on AI driven flows.

• Build the verification plan across levels: module-level simulation, SoC integration,
  
  

interface checks, top-level IO, and how each feeds the validation plan.

• Specify, evaluate and Integrate third party VIP into the environment
  
  

Own gate-level simulation with SDF-annotated timing as part of tapeout closure.

• Extend our FPGA-based verification harness so modules can be exercised with real
  
  

code, quickly, without burning simulator licenses.

• Stand up and operate our emulation environment, including provisioning and execution
  
  

on cloud-hosted infrastructure.

• Use AI tooling to generate and iterate testbenches and assertions, optimizing based on
  
  

coverage feedback, and iterating to ensure high quality verification.

• Build and lead the verification team, partnering with system architecture, RTL design,
  
  

physical design, DFT and validation.

Qualifications

• 8 to 15 years in design verification, including leading verification on a GPU-class or
  
  

complex compute ASIC through tapeout.

• Deep UVM and SystemVerilog expertise, including ownership of testbench architecture,
  
  

formal verification, coverage analysis and CI/CD methodology.

• Gate-level simulation experience. You know what gate sim costs you in visibility and
  
  

where it belongs in a tapeout schedule.

• Verification experience on a chip with many independently developed blocks and analog
  
  

components, including integration of analog models.

• Comfort standing up a verification environment end to end, including emulation
  
  

infrastructure.

• Breadth across the flow, from module-level simulation through SoC integration and into
  
  

validation planning.

Preferred Skills

• Hands-on emulation experience, Palladium or equivalent.
• Development of analog models using WREAL or equivalent descriptions
• FPGA-based verification or prototyping experience.
• Cadence toolchain experience.
• Experience using AI tooling to accelerate testbench development and coverage closure.
• Exposure to silicon photonics or optical component verification.
