Principal Product Engineer

About the role

HistoSonics is a commercial-stage medtech company advancing the Edison® System, a novel non-invasive sonic beam therapy based on histotripsy. Since receiving FDA De Novo grant for the non-invasive destruction of liver tumors in 2023, the company has progressed beyond initial market entry into commercial expansion, reimbursement momentum, and ongoing clinical and pipeline development. In addition to its current liver tumor indication, HistoSonics is pursuing future indications across multiple applications including kidney, pancreas, prostate, neuro, women’s health, and other significant underserved human health areas, to realize the broader potential histotripsy across multiple disease states and medical specialties. We offer an exciting work culture where cutting-edge science meets real-world application, and each team member’s contribution is important to our success in ensuring our physicians and their patients get what they need most.
