Q Bio is building technology for the Physical of the Future that measures more, faster and cheaper about the human body, to enable proactive primary care for all. We're revolutionizing primary care with the first clinical digital twin platform, powered by breakthrough whole-body scanning technology, that highlights the most important changes in a person’s physiology for sharing with physicians and specialists anywhere in the world.
Join us!
Q Bio’s clinical digital twin platform, Gemini, is the first to capture and monitor comprehensive baseline patient health in a scalable virtual model. The Gemini Dashboard highlights the most important chemical and anatomical changes in an individual weighted by an individual’s lifestyle, genetic and medical history, that can be securely shared with physicians and specialists all over the world.
Gemini is powered by the fastest, most accessible, whole body scanner developed: the Mark I. Self-driving and optimized for primary care, the Mark I can complete a whole-body scan in 15 minutes or less in an open space, without radiation, breath holds, or claustrophobia. Patient comfort is maximized with the option to sit, stand, or lie down, and real-time telemetry is displayed throughout.
Why should you consider a career with Q Bio?
We dream big. Our team is aligned and excited about the opportunity to save lives and understand the human body like never before. We know how critical empowering and supportive leadership is, both to our excellence as a company, and for our team experience as a whole, and our leadership team will empower and support career growth. We’re a team of engineers, scientists, and operators who come from a diverse background of disciplines and experiences. We value teamwork, growth, determination and persistence, commitment to collaboration, and a reliance on staying nimble while keeping the big picture in mind.
Join our team and lead the development of cutting-edge quantitative MRI techniques, creating a comprehensive whole-body Digital Twin. From concept to deployment, you will play a critical role in shaping the future of MRI technology and bringing it to the forefront of medical innovation.
As a Senior Mechanical Engineer, you will be responsible for the design, prototyping, and productization of the mechanical system for the crucial component of Q Bio Mark I: the superconducting magnet. You will play a critical role in the development of the most accessible MRI scanner ever developed and be part of a paradigm shift in health care and precision medicine!
