Company Description

Butterfly Network has created and brought to market the Butterfly IQ – the first FDA-cleared, portable device that puts ultrasound technology on a semiconductor chip. Pairing ultrasound-on-a-chip with the cloud and AI, we are doing something never done before, and bringing ultrasound to new domains around the world.

Since inception, Butterfly has raised over $375 million.

As we scale our team, we are seeking the best and the brightest engineers, across both the software and hardware worlds.

Job Description

The FPGA is at the heart of our revolutionary Butterfly iQ ultrasound device.   As a designer of this part, you will work closely with our ASIC, EE, Imaging, and Firmware teams.  Your role will be to convert complex beamforming algorithms (how the sound waves are converted into images) into Verilog, to accelerate these algorithms into working prototypes, and to verify the designs for customer shipments.  You will be responsible for the selection of next generation FPGA devices, and working with your ASIC and EE colleagues, will develop the high-speed interfaces to pipeline the ultrasound data.  Working with your embedded colleagues, you will select and implement an embedded microprocessors.
