Marketing Lead, Growth Marketing

We are seeking an experienced, technically sharp marketing lead for Shopify's 3P Shop Campaigns program. You will own performance, experimentation, and scaling of our Google product advertising portfolio (Performance Max, Shopping, Search Ads), with the opportunity to expand into additional emerging channels over time. This is not a typical paid media role. You will operate at the intersection of marketing, product feeds, and engineering. A significant part of your work involves managing campaigns with aggressive ROAS targets and expanding the product catalog that powers our ads: millions of merchant products flowing through feed pipelines, eligibility filters, and Google review processes. You will partner closely with engineering and data science teams on catalog health, conversion signal infrastructure, and measurement rigor. The right person combines hands-on feed/shopping campaign experience with the strategic ability to manage a channel portfolio against efficiency targets, design high-velocity experiments, and communicate performance and trade-offs clearly to leadership.
