Distinguished Engineer, Digital ASIC

Company Description

At Butterfly Network, we’re leading a digital revolution in medical imaging, transforming an industry that has long relied on bulky, analog systems. With our proprietary Ultrasound-on-Chip™ technology, we’re democratizing healthcare by shifting ultrasound from the expensive, stationary systems of the past to the connected, mobile, and software-enabled platforms of today. In 2018, we launched the world’s first handheld, whole-body ultrasound, Butterfly iQ – followed by iQ+ in 2020 and iQ3 in 2024, each more powerful than the last. Our innovation doesn’t stop at hardware. Butterfly combines our advanced device with intelligent software, AI, services, and education to drive adoption of affordable, accessible imaging. Our technology is proving to help clinicians, clinics, and hospitals enhance care, cut costs, and expand imaging access. We’ve been recognized by Prix Galien USA, Fierce 50, TIME’s Best Inventions, Fast Company’s World Changing Ideas, among other awards. We’re a team of bold thinkers, problem-solvers, and innovators ready to shape the future of medical imaging. Let’s build something extraordinary together!

Qualifications

Baseline skills/experiences/attributes:

• BS/MS/PhD in EE/CE/CS or equivalent practical tapeout experience.
• 8–12+ years (typical Principal level) in digital IC / ASIC / SoC design with significant hands-on RTL ownership.
• Strong understanding of digital IC implementation at the silicon level, including timing closure implications, clock/reset domain architecture, power-aware design, and PPA (power, performance, area) tradeoffs.
• Proven ability to own complex digital IC subsystems from architecture and PPA tradeoffs through RTL implementation, verification signoff, and tapeout handoff to physical design.
• Strong RTL skills in SystemVerilog/Verilog to implement silicon-proven digital architectures, including pipelined datapaths, control logic, state machines, and high-throughput streaming interfaces.
• Experience architecting sustained high-throughput digital datapaths, including buffering, arbitration, backpressure, bandwidth budgeting, and SRAM/memory hierarchy design.
• Prior work at advanced technology nodes (28nm or smaller), including timing closure challenges and integration of third-party IP.
• Experience collaborating with verification teams to validate complex digital architectures and resolve functional issues through tapeout signoff.
• Comfortable working cross-functionally with analog, systems, and packaging/board teams to close chip-level requirements and integration details, including hardware–firmware interfaces (register maps, control/status paths, data-plane contracts).

Ideally, you also have these skills/experiences/attributes (but it’s ok if you don’t!):

• Experience implementing compute-intensive digital pipelines (e.g., DSP, beamforming, AI, or MAC-heavy/vector datapaths).
• Exposure to medical imaging / ultrasound systems, beamforming pipelines, or sensor data acquisition architectures.
• Experience designing or integrating programmable digital compute blocks (e.g., AI accelerators, MPUs, or eFPGA fabrics), including instruction/control interfaces, memory hierarchy, data movement, and PPA tradeoffs.
