About Tiny Health

Tiny Health is advancing lifelong health, from the first 1,000 days to the last, and addressing chronic disease through precision microbiome science. Founded in 2020 and built by microbiome scientists and physicians, our testing platform reveals whether your microbiome is trending toward resilience or imbalances using shotgun metagenomics, proprietary AI, and one of the world's largest longitudinal datasets. Trusted by families and health practitioners alike, our research-backed gut and vaginal tests are redefining the microbiome as a cornerstone of personalized health through every life stage.

We’re hiring a Lifecycle Marketing Manager to own the entire customer journey — from the moment someone discovers Tiny Health through member retention.

Email and SMS are your primary channels, but you’ll also shape how we use direct mail, in-app messaging, and other touchpoints to keep our customers engaged, drive repeat purchases, and deepen their relationship with Tiny Health over time.

You’ll collaborate closely with our growth, content, and product teams, and take full ownership of our lifecycle agency relationship, setting direction and holding them accountable to performance.
