ASIC Test Engineer

  • 530 Whitfield St, Guilford, CT 06437, USA
  • Full-time

Company Description

At Butterfly, we are building a device that will make medical imaging accessible to everyone in the world. We have reinvented ultrasound by integrating core components into a single silicon chip. The result is a high performance imager that is more portable and less expensive than any other system in the world. The system's on-board Deep Learning Algorithms, trained by ultrasound experts, will guide clinicians with less expertise. It’s a breakthrough that will save millions of lives.

Job Description

The ASIC Test Engineer is a key member of Butterfly’s semiconductor product team, including characterization, test, product and packaging engineers. The individual will work closely with the ASIC and sensor design teams, as well as the imaging, product and operations teams.
