Job Description
The role of the Staff Digital Verification Engineer offers the opportunity to work at the core of the product development team alongside company leadership and founders, helping ensure the correctness and robustness of the digital systems that differentiate Butterfly Network's products. This individual will be responsible for architecting, developing, and executing comprehensive verification strategies for complex digital signal processing blocks, high-speed interfaces, and large system-on-chip (SoC) designs used in next-generation ultrasound imaging platforms.
As a senior member of the engineering team, you will drive verification methodology, automation, and infrastructure to enable rapid development and high confidence in silicon correctness.
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.

Qualifications

• 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 processors or accelerator subsystems.
  Experience with ECO or system-level validation flows.
