Growth Marketer Jobs at Mammoth Brands

Mammoth Brands (formerly Harry’s Inc.) is the modern CPG company behind brands Harry’s, Flamingo, Lume, Mando, and Coterie. We’re building a new model—and home—brands, founders, and talent looking to solve unmet needs, improve peoples’ lives, and ultimately challenge the status quo. Our mission is to “Create Things People Like More.” Simply put: everything we do should be better than what already exists. If it’s not, we don’t do it. This guides everything we do, from developing the best product experiences, to making Mammoth Brands a great place to work, to exploring innovative ways to give back to our community.

A Growth Marketer owns the strategy and execution of scalable, data-driven campaigns designed to grow a product's user base and revenue. Day-to-day, they identify growth levers across acquisition, activation, retention, and referral channels, design and run A/B and multivariate experiments, analyse funnel performance, and iterate rapidly on what works. They collaborate closely with product, engineering, and data teams to implement growth loops, optimise conversion rates, and reduce churn, treating marketing as a continuous cycle of hypothesis, test, and measurement rather than a series of one-off campaigns.
