Growth Marketing, Sr. Associate - New Channels | Acorns

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, Acorns Early, and GoHenry.

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.

This role is being offered on a contract basis with an expected duration of 6 months with potential to expand based on business need and requiring 40 hours of work per week.

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

• 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.

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 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, 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.

• 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.

What You Will Bring

• 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. Exposure to Marketing Mix Modeling (MMM) is a plus.

• 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;
