Growth Marketing Manager

GrowthAssistant•St. Louis, MO

About The Position

GrowthAssistant embeds elite global talent with growth-obsessed founders and marketing teams. We help companies scale faster, smarter, and more affordably. In just four years of profitable growth, we’ve scaled to over $20M of revenue and work with industry-leading clients such as DoorDash, Shopify, and Harry’s. We’re a fast-growing, entrepreneurial company focused on building scalable systems, strong teams, and long-term partnerships. We’re looking for a Growth Marketing Manager to own and scale our content- and event-driven demand engine — with a performance mindset. This role is for someone who thinks in systems and funnels, not just formats. You’ll treat webinars, in-person events, and content as measurable growth channels, continuously improving how they drive engagement, pipeline, and revenue. You’ll design programs, test and learn quickly, and build repeatable playbooks that get stronger over time. This is a hands-on role on a small team, so comfort with ambiguity, ownership, and evolving scope is essential.
