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. Why Join Us You’ll be part of a collaborative Growth team that values creativity, experimentation, and impact. With access to significant budgets, a strong data-driven culture, and exposure to cross-functional experts, you’ll have the opportunity to accelerate your performance media craft, while directly contributing to scaling our business. Key Responsibilities Portfolio & Campaign Management Own day-to-day operations of our Google product advertising program (Performance Max, Shopping, Search Ads & more), managing campaigns against revenue ratio and efficiency targets globally. Design and execute high-velocity testing pipelines across bidding strategies, campaign structures, audiences, creative, and landing pages. Over time, extend ownership to additional emerging channels as the portfolio evolves, managing a tiered channel strategy with structured experiments and clear kill criteria. Catalog & Feed Management Own the health and growth of the product catalog that powers all advertising: eligibility rules, feed quality, Google Merchant Center policies, and disapproval resolution. Monitor catalog coverage and identify scaling levers, including eligibility filter tuning, MCA suspension reduction, and feed enrichment opportunities. Partner with product and engineering teams on catalog pipeline improvements and product vetting automation. Conversion Signals & Measurement Partner with engineering to maintain and improve conversion signal pipelines, ensuring signal quality, match rates, and attribution accuracy. Work with data science on incrementality measurement, attribution model calibration, and valuation frameworks that inform spend allocation decisions. Monitor signal health (click ID coverage, event volumes, platform-reported vs. internal attribution gaps) and escalate anomalies. Cross-Functional & Communication Work with creative strategy to develop effective product advertising programs across the funnel. Actively communicate program performance, financial health, and strategic trade-offs to marketing leadership and finance stakeholders. Qualifications A successful track record managing SEM and product-feed-based advertising campaigns at scale (Shopping, Performance Max, or equivalent), with demonstrated ability to hit efficiency targets. Direct experience with product feed management and merchant center operations: feed diagnostics, disapproval resolution, eligibility optimization, and catalog scaling. Experience with SQL. You may not be able to write complex queries from scratch, but you have a high-level understanding of databases and how to query them. Working knowledge of conversion tracking infrastructure: server-to-server signals, click ID mechanics, attribution windows, and how signal quality affects platform bidding. Experience partnering with engineering and data science teams on technical marketing problems (feed pipelines, attribution, measurement frameworks). Ability to design structured experiments with clear hypotheses, kill criteria, and measurement plans. Strong stakeholder communication skills: you can translate technical performance data into clear narratives for marketing leadership and finance. Ability to thrive in a fast-paced environment and can navigate through ambiguity and work with minimal guidance.
