Company Description:


Cosm Medical is a medical device company building a platform for Personal Pelvic Health to improve the lives of women affected by pelvic floor disorder. Pelvic floor disorders, including pelvic organ prolapse, urinary and fecal incontinence, drastically decrease quality of life. These disorders are common (affects 1 in 4 adult women), growing (affects half of all women by 80 years of age) and underserved. The current non-surgical treatment for pelvic organ prolapse is the use of pessaries, which are intravaginal inserts that come in 100+ different sizes and shapes and are fit by trial and error, resulting in a relatively low success rate and quality of life.

At Cosm, we are developing Gynethotics™, or made-to-measure gynecological prosthetics, to replace pessaries and manage pelvic organ prolapse, incontinence and more. Our goal is to transform the art of pessary fitting into the science of Gynethotics™ by leveraging cutting-edge technologies like 3D printing, AI, cloud software, and point-of-care diagnostics. 

This is an opportunity to join our growing team that is leading the way in creating a new personalized medical devices category for underserved women’s health conditions. Join our mission for Personalizing Pelvic Health!

COSM is an equal opportunity employer and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, sexual orientation, gender identity, disability status, protected veteran status, or any other characteristic protected by law.
