Responsibilities:

• Support the development and execution of a structured testing roadmap for new and emerging paid media channels, including programmatic display, Reddit, Snapchat, and alternative platforms
• Manage day-to-day campaign setup, trafficking, and pacing across new channel tests, exercising judgment on optimizations and escalating to the Senior Paid Acquisition Manager on larger strategic decisions
• Partner with the Creative team to brief and iterate on ad assets tailored to new platform environments
• Identify incrementality and lift study opportunities, collaborate with the Analytics team to design the test structure, and own the launch and ongoing performance monitoring of each experiment
• Track and report on key performance indicators for new channel initiatives, translating data into clear summaries for internal stakeholders
• Maintain organized records of test results, learnings, and optimization actions to build a shared knowledge base for the team
• Support acquisition growth across our brand portfolio—Acorns, Acorns Early, and GoHenry—with a focus on US-based performance
• Work collaboratively with Analytics, Creative, and other marketing teammates to execute experiments efficiently and surface actionable insights

Requirements:

• 3–5 years of experience in performance marketing, paid media, or growth marketing with a BS/BA; or equivalent work experience
• Hands-on experience with at least one paid media platform (e.g., Meta, Snapchat, Reddit, The Trade Desk, or similar)
• Familiarity with mobile measurement platforms (e.g., Adjust, AppsFlyer) and an understanding of how attribution frameworks inform paid media decisions
• A data-driven mindset—you're comfortable working with performance data and translating numbers into clear, actionable takeaways
• Strong organizational skills and attention to detail; you follow processes carefully, flag questions early, and aren't afraid to modify your approach when the situation calls for it
• Clear written and verbal communication skills—you can summarize experiment results and share channel recommendations in a way that's easy for stakeholders to act on
• Genuine curiosity about where digital advertising is heading and a hunger to explore channels competitors aren't using yet
• A belief that your work is connected to something bigger—helping everyday people build financial security is core to what we do at Acorns, and we want teammates who are energized by that mission
• Exposure to Marketing Mix Modeling (MMM) is a plus
