R&D Test Engineer II

Title: R&D Test Engineer II Company Summary: Join a team that’s redefining what’s possible in cardiovascular treatment. At Jupiter Endovascular, we’re revolutionizing catheter-based therapies by bringing the precision and control of surgery to minimally invasive procedures. For decades, catheters have remained largely unchanged—rigid, unstable, and difficult to maneuver through the body’s winding anatomy. We’ve developed a transforming fixation technology that navigates flexibly through the vascular system, then locks into place to deliver treatment with surgical-like stability and control. Our device solves one of the longest-standing challenges in endovascular procedures, empowering physicians and improving outcomes for millions of patients living with cardiovascular disease. We’re entering an exciting new phase—scaling up production, expanding our team, and preparing for commercial launch. Founded and headquartered in Menlo Park, California, Jupiter Endovascular is led by a proven team of medical device entrepreneurs and backed by top-tier investors across venture capital, private equity, and strategic partners. We’ve built a fast-paced, collaborative culture grounded in innovation, teamwork, and purpose. Every role at Jupiter directly contributes to our mission: saving lives by advancing the future of endovascular therapy.
