Principal Engineer, Electrical Engineer

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!
