Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. They work across business groups and around the globe, spanning time zones and disciplines to develop inclusive People policies, forecast finances, give legal counsel, safeguard systems, nurture new initiatives, and more. Every challenge creates possibilities, and we need different perspectives to see them all. Bring yours to Block. The Role The Cash App Engagement Marketing team builds deep, personalized relationships with our customers across their entire lifecycle, from sign-up through long-term habituation. We operate at the intersection of growth strategy, lifecycle execution, and product, and our work directly shapes how millions of customers discover Cash App, build daily habits with the product, and grow with us over time. We're looking for an Engagement Marketing Manager focused on activation and habituation. This is not a traditional lifecycle marketing role. The shape of engagement marketing is changing fast. Personalization, AI decisioning, and in-app surfaces are reshaping how the work gets done, and this role sits at the front of that change. The candidates who thrive here bring analytical depth and an experimentation reflex alongside their marketing instincts. You'll work as part of a tightly integrated cross-functional team alongside Product, Engineering, ML, Design, and Analytics counterparts, chartered to drive conversion, activation, and habituation across the full Cash App customer journey. You'll operate more like a growth strategy owner than a campaign marketer: sizing opportunities, designing rigorous experiments, diagnosing funnel friction, and shipping fast. The experiments you run won't just shape our communications. They'll directly influence what gets built next. This Role You'll run experiments at the scale of one of the largest consumer fintech audiences in the world. Signal density is unusual and learning compounds fast. Because you're embedded with Product partners, your experiments shape not just our communications but our product roadmap. You'll help define what engagement marketing looks like when comms decisioning is increasingly AI-driven. Every experiment you run feeds, and is shaped by, the AI and automation stack we're building. You Will Own activation and habituation outcomes end-to-end: define the opportunity landscape across the customer journey, set strategy, prioritize ruthlessly, and deliver measurable business impact Operate as a peer to Product, Engineering, ML, and Design. Your experimentation learnings shape the product roadmap, not just the comms calendar Run a high-velocity experimentation program across onboarding, post-onboarding upsell, contact opt-in, churn prevention, behavioral notifications, real-time intervention journeys, mobile wallet adoption, referrals, retention, and winback Build and maintain a unified opportunity framework where every test is scored against expected impact and effort, prioritized agnostic of product or surface Self-serve sophisticated analysis: sizing opportunities, diagnosing funnel friction, reading experiment results, and iterating without reliance on dedicated analytical partners. SQL fluency and data modeling intuition are core to this role Push the frontier on AI decisioning and automation, and help define how engagement marketing evolves as AI moves further into the comms decisioning layer Influence cross-functional strategy across Product, Analytics, Martech, Creative, and Brand, operating as a true peer of these teams, not a downstream of them You Have 5+ years of experience in lifecycle marketing, CRM, growth marketing, growth strategy, business operations, growth product, or a consumer-facing analytical role in a B2C tech environment
