Senior Growth Marketing Manager

Seed Health is a microbiome science company pioneering clinically validated innovations for gut and whole-body health. Our portfolio of gut-directed products is developed in collaboration with leading scientists and backed by human clinical research. We’re best known for DS-01® Daily Synbiotic—the #1 digestive health probiotic in the U.S.—trusted by millions of people for its benefits in and beyond the gut, including skin, immune, and heart health.

We’ve since expanded our offerings to include PDS-08® for pediatric health, VS-01™ for vaginal health, and a new category of Co-Biotics for daily nutrition, energy, and sleep—each grounded in our commitment to scientific rigor, precision formulation, and impact across the body’s interconnected systems. Beyond the body, SeedLabs—our environmental research division—advances microbial solutions that restore biodiversity and support ecosystems affected by human activity.

We’ve built a profitable DTC business with category-leading retention, grown revenue 5x in the last 36 months, and expanded our reach across new channels and markets. With a robust clinical pipeline and continued expansion into new areas of microbiome health, we’re building for scale—with integrity, care, and curiosity.

Our work has been recognized by Fast Company (Most Innovative Companies, Brands That Matter, World Changing Ideas), TIME (Best Inventions), Forbes (America’s Best Startup Employers), and Inc. (Best in Business, Female Founder 100)—a reflection of the science behind our products and the stories we tell to bring them into the world.

We’re a galaxy-class team of researchers, clinicians, designers, engineers, storytellers, and builders—each aligned in our belief in the transformative potential of the microbiome. If you’re a kindred dot-connector looking to shape the future of health, join us.
