About the role

  • Butterfly first proved its technology in the point-of-care ultrasound market - commercializing the world's first single-probe, whole-body portable ultrasound device, which is now on its best-selling, third-generation: Butterfly iQ3™.
  • Butterfly also enables third-party development of imaging AI apps through Butterfly Garden™, its software development kit and AI partnership initiative.
  • Butterfly's innovations have been recognized by Prix Galien USA, Fierce 50, TIME's Best Inventions and Fast Company's World Changing Ideas, among other achievements.

Responsibilities

  • Architect and develop verification environments for large SoC subsystems using Python-based frameworks, primarily Cocotb.
  • Develop bit-accurate reference models (Python) to validate DSP and fixed-point behavior.
  • Develop and maintain automated regression infrastructure and CI pipelines using GitHub-based workflows.
  • Work cross-functionally with architecture, RTL design, firmware, and system teams to ensure robust end-to-end functionality.
  • 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.

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.
  • Proven experience verifying large digital IP blocks or SoC subsystems through full verification closure and tapeout cycles.
  • Experience verifying high-bandwidth streaming architectures and large on-chip data pipelines.
