Senior R&D Engineer – Heart Valve Frame Design

October 9th, 2018

HLT, Inc. is a clinical-trial stage company founded in Minnesota in 2002. We manufacture a transcatheter heart valve system, consisting of a catheter-based delivery system and heart valve, to treat aortic valve disease.  The procedure is performed by an interventional cardiologist / cardiac surgeon in a cardiac catheterization laboratory, and is expected to be both less invasive and less costly than an open heart valve replacement procedure.  The company currently employs approximately 100 people in Maple Grove, Minnesota.

In 2010 HLT was acquired by The Bracco Group, an international company active in the healthcare sector through Bracco Imaging. The group employs more than 3,300 employees worldwide and has annual total consolidated revenues of more than $1 billion.

HLT seeks passionate and talented people who can start contributing from day one. We want innovators seeking to advance the state of the art to improve patient outcomes.
