The Opportunity

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’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!

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