Director of Marketing - 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. 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.

At 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 will be our marketing function. Not lead a team. Not manage agencies. Be the function. You will use AI tools aAnd automations to operate at the scale of a 3-person team, owning organic acquisition, content, SEO, community, and lifecycle marketing.

This is a rare opportunity for a scrappy, analytical, AI-native marketer to build from scratch at a mission-driven company. If you are energized by experimentation, live in the data, and want your work to directly improve the lives of patients and caregivers, we would love to meet you!

• Own organic acquisition: Run experiments across SEO, content, community (Reddit, advocacy partnerships), and referral channels.

• Run the content engine: Take over podcast, newsletter, blog, and social. Publish 8-10 blog posts monthly using AI-assisted workflows.

• Build lifecycle marketing: Create email sequences and re-engagement campaigns. Partner with product on activation.

• Measure everything: Set up tracking, build dashboards, run cohort analysis. Know your numbers cold.
