Founding Front End Engineer - Manta Cares

About Manta Cares

Navigating cancer is like embarking on a treacherous hike—without a map, gear, or guide. Manta Cares provides the most comprehensive self-advocacy toolkit available, empowering patients every step of the way, transforming the cancer journey.

Manta Cares is a digital health company founded and led by cancer patients, survivors, caregivers, and oncologists. Our team brings over 50 years of combined healthcare experience, with backgrounds at McKinsey, Stanford, MIT, and ASCO, among others. Backed by top-tier venture funds—including Pear Ventures, Sozo Ventures, and 1843 Capital—we generate revenue through partnerships with leading life sciences organizations.

A lot of what we do today is in stealth mode, and you will need to chat with us to truly learn more (our website will only tell you so much!).
