Software Engineer - Technical Lead

Cosm Medical is a Toronto-based medical device company. Our goal is to transform the way pelvic floor disorders are treated thanks to 3D printing, AI and cloud software, and create Personalized Pelvic Health. 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 (stigmatized and traditionally low priority vs.

other health concerns). 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.

Cosm is commercializing the world’s first personalized pessary, Gynethotics™, or made-to-measure gynecological prosthetics, aimed to improve patient satisfaction and outcomes compared to off-the-shelf devices, alongside a software platform to streamline the pessary practice.

The job is located at Cosm’s manufacturing lab at the MaRS Accelerator (101 College St.) in Toronto’s world-renowned Healthcare Technology Hub.

The Software Developer/Technical Lead will work closely with Cosm Medical’s engineering team, data scientists, product stakeholders, and external software development partners to architect, develop, integrate, and maintain Cosm’s proprietary software platform. The portfolio spans the development of AI-enabled medical imaging software platforms, including customer-facing web, mobile, and local applications, as well as supporting internal infrastructure and clinical workflow tools. This role will own the technical software stack and lead the development and evolution of scalable, secure, and compliant software systems supporting Software as a Medical Device (SaMD) solutions for medical imaging.

Responsibilities include software development, software architecture, technical leadership, cloud infrastructure, cybersecurity, development oversight, software verification and validation coordination, and regulatory documentation support within a medical device quality management system.
