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. We are transforming the cancer journey.
We are 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, BCG, Stanford, MIT, Harvard, IDEO, and ASCO. Backed by top-tier venture funds including Pear Ventures, Sozo Ventures, and 1843 Capital, we are generating revenue through partnerships with leading life sciences organizations.
The OpportunityAt Manta Cares, marketing is how we earn trust. It is how patients discover us, how families feel supported, and how our mission reaches the people who need us most. As Director of Marketing, you’ll build and own this trust-building function from the ground up. This is an exciting, hands-on role for someone who loves executing, testing, and building systems.
We’re a lean company operating in a moment where AI and automation are redefining what’s possible at work. We want someone excited to use modern tools to scale our business efficiently. Over time, this role can evolve into Head of Marketing, leading a lean team and select agency partners - but to get there, we need a data-driven person willing to build the foundation the company will scale on.
This is a rare opportunity for a scrappy, analytical marketer to build from scratch at a mission-driven company. If you are energized by data, experimentation and want your work to directly improve the lives of others, we would love to meet you!
