Growth Marketing, Sr. Associate - Paid Social/New Channels

Acorns is looking for a curious, driven Growth Marketing Sr. Associate to join our team and help expand our paid acquisition channel mix. You will work closely with the Senior Paid Acquisition Manager to research, launch, and scale emerging platforms—from programmatic DSPs to community-based channels like Reddit—driving user growth across Acorns and Acorns Early.

This role carries real ownership. You’ll operate with meaningful day-to-day autonomy, exercise judgment within established frameworks, and produce analysis and recommendations that shape how we invest in new channels. You’ll collaborate cross-functionally with Analytics, Creative, and channel partners to bring experiments to life and move quickly from proof of concept to scaled channel.

Acorns is a remote-first organization, offering the flexibility to work remotely while providing optional access to office space in Irvine, CA.

What You Will Do

Channel Testing & Execution

• Help develop and execute a structured testing roadmap for new and emerging paid media channels, including programmatic display, Reddit, Snapchat, and other alternative platforms.
• Own day-to-day campaign management across existing channels like Meta, TikTok, Snap, Reddit, and YouTube.
• Run tests on new channels, including setup, trafficking, pacing, and ongoing optimization.
• Use performance data and judgment to make in-channel optimizations, escalating broader strategic decisions to the Senior Paid Acquisition Manager as needed.
• Partner with the Creative team to brief, test, and iterate on ad assets tailored to each platform and audience.

Measurement & Reporting

• 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 and existing 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.

Cross-Brand & Cross-Functional Collaboration

• Support acquisition growth across our brand portfolio—Acorns and Acorns Early.
• Work collaboratively with Analytics, Creative, and other marketing teammates to execute experiments efficiently and surface actionable insights.
• Actively monitor the AdTech landscape—including gaming platforms (e.g., Roblox, Discord), community platforms, and emerging programmatic DSPs—and bring forward channel opportunities for the team to evaluate.
