Growth Manager, Paid Social

About the role

Stash is passionate about democratizing wealth creation through education, advice, and products that help customers achieve greater financial freedom. We leverage AI and emerging technologies to move faster, operate more efficiently, and focus on solving meaningful problems for our customers. The Growth Manager, Paid Social will own Stash's paid social and mobile ad network acquisition, reporting to the Sr. Director of Acquisition. This role has real scope and huge impact: you'll run hands-on media, build a disciplined experimentation system, and use AI-enabled workflows to operate at higher velocity. You'll partner closely with our Performance Creative Strategist to build a highly performant paid social engine, with potential to expand into additional performance channels over time. This position operates on a hybrid schedule, requiring you to be on-site in our New York office at least three days per week.

Responsibilities

• Develop and own strategy and execution for paid social (Meta, TikTok) and mobile ad networks (AppLovin), focusing on efficient new customer acquisition
• Manage budgets, pacing, bidding, audience/structure decisions, and optimization to improve CAC, payback, and scalable growth
• Build and manage a testing roadmap that keeps a constant stream of media experiments in market
• Own acquisition landing page experimentation tied to your channels—prioritize the test backlog, define success metrics, and ship/kill/scale based on performance
• Partner with the Performance Creative Strategist on message match between ads and landing pages; own the performance readout and decisioning
• Identify and implement AI-driven tools and workflows that accelerate reporting, optimization, experiment tracking, and day-to-day media ops
• Analyze performance data to identify what's working, what's decaying, and where the next dollar should go
• Turn learnings into new hypotheses across targeting, bidding, structure, offers, and landing pages
• Report on channel and funnel performance and share insights with the broader acquisition and marketing teams
• Collaborate tightly with the Performance Creative Strategist to close the loop between creative, partners, and paid media (including whitelisting/Spark where creators feed paid)
• Partner with Data, Product, Brand, and Martech on attribution, incrementality, and measurement
• Provide media input on campaign planning and, over time, expansion into additional performance channels

Requirements

• 4–6 years of hands-on experience buying and optimizing paid social (Meta and/or TikTok), with a track record tied to performance metrics (CAC, payback, ROAS, new customer acquisition)
• Deep knowledge of working with MMPs (e.g., AppsFlyer)
• Experience building and executing testing roadmaps across media and landing pages
• Strong analytical skills—comfortable with performance data, experiment design, and translating insights into action
• Bias for speed and ownership; experience operating with AI tools or automation to increase leverage is a plus
• Strong communication skills, with the ability to partner effectively with creative, data, and cross-functional stakeholders

Preferred qualifications

• Experience with mobile ad networks / UA platforms (e.g., AppLovin) or strong adjacent mobile performance experience
• Experience owning landing page / CRO testing for acquisition funnels
• Familiarity with fintech, consumer finance, or another regulated industry
• Experience with incrementality testing, attribution, or media mix measurement
• Experience standing up or scaling additional performance channels beyond social/mobile
• Curiosity and familiarity with AI tools that can help streamline and improve processes

Benefits

• Comprehensive total rewards package, comprising compensation (salary and equity) and health care benefits
• Complimentary subscription to Stash+ account
• Hybrid work environment in NYC with work-from-home flexibility
• Flexible PTO
• Work-from-home equipment stipends; home internet subsidy
• Paid Parental Leave (offerings for birth giving and non-birth giving parents, Primary & Secondary)
• Enhanced health and wellness benefits through One Medical, Gympass, and Maven Health

Pay

Salary range: $140,000 – $160,000 base salary. Actual salaries will vary based on the candidate's qualifications, skills, experience and competencies, as well as internal equity and alignment with market data for companies of our size and industry.
