What we need to build next is the infrastructure that gets us in front of people before they know they need us: the organic surfaces, the conversion flows, and the product loops that turn a midnight Google search into a Marble client, and a Marble client into a referral. That's what this role is for. As Senior Growth PMM, you'll sit at the intersection of marketing's demand insight and product's build capacity — owning the full client conversion journey from first consideration through the product-led growth motions that make Marble self-sustaining. You'll make growth infrastructure actually happen by selling the vision internally, writing specs Product can act on, and getting things shipped in sync with marketing demand goals. What You Will Do Opportunity Identification In this strategic role, you will be leading growth opportunity identification, including market research, competitive intelligence, consumer insights, creatively innovating on new plays, and ultimately building the strategy. Sell the Vision Growth infrastructure only happens when product and engineering believe it's worth building. You'll build the business case for each initiative you identify — OKR alignment, expected impact on lead volume and closed won, build effort, time to impact — and present it in a way that earns trust across functions. You'll think long-term and short-term simultaneously, knowing which initiatives compound over 12 months and which move the needle in 30 days, and sequence accordingly. Write the Spec You'll translate marketing's demand insight into product requirements that Product can act on without ambiguity or wasted cycles. You'll own the requirements for every growth infrastructure initiative — conversion funnels, SEO tools and calculators, multi-language journeys, AI intake flows, Product-Led-Growth (PLG) surfaces, and infrastructure for new channel builds.
