Staff Engineer, Digital Verification

Responsibilities

• As part of our team, your core responsibilities will include:
• Architect and develop verification environments for large SoC subsystems using Python-based frameworks, primarily Cocotb.
• Design and implement self-checking testbenches, constrained stimulus, scoreboards, and coverage infrastructure.
• Develop bit-accurate reference models (Python) to validate DSP and fixed-point behavior.
• Verify complex digital signal processing blocks, high-speed interfaces, and system-level datapaths.
• Collaborate closely with RTL designers to define verification plans, drive coverage closure, and ensure design correctness.
• Develop and maintain automated regression infrastructure and CI pipelines using GitHub-based workflows.
• Debug functional issues in simulation, emulation, and post-silicon environments.
• Contribute to improving the verification methodology, productivity tools, and infrastructure used across the team.
• Work cross-functionally with architecture, RTL design, firmware, and system teams to ensure robust end-to-end functionality.

Requirements

• BS/MS/PhD in EE/CE (or equivalent practical experience in digital verification).
• 8+ years (typical Staff level) experience in digital IC / ASIC / SoC verification.
• Strong experience building and maintaining Python-based verification environments, particularly Cocotb.
• Deep knowledge of SystemVerilog and digital design concepts sufficient to effectively verify complex RTL.
• Proven experience verifying large digital IP blocks or SoC subsystems through full verification closure and tapeout cycles.
• Experience building self-checking testbenches, scoreboards, monitors, and stimulus generators.
• Experience developing bit-accurate Python models for algorithm verification and golden reference comparison.
• Strong debugging skills across simulation, waveform analysis, and root-cause analysis of RTL issues.
• Experience building automated regression frameworks and CI workflows using GitHub or similar tools.
• Solid understanding of SoC design challenges including CDC/RDC verification, reset architecture, and power-aware verification.
• Strong cross-functional communication skills working with RTL designers, architecture teams, and firmware engineers.
• Preferred (but not required):
• Experience verifying compute-intensive DSP pipelines (e.g., beamforming, filtering, MAC-heavy datapaths).
• Familiarity with ultrasound or medical imaging signal processing pipelines.
• Experience verifying high-bandwidth streaming architectures and large on-chip data pipelines.
• Exposure to advanced node SoCs (28nm or below).
• Experience integrating and verifying embedded processo
