Senior Lifecycle Marketing Manager

We're looking for a Senior Lifecycle Marketing Manager to join our Lifecycle Marketing team at Square. In this role, you'll lead strategic initiatives that drive revenue, optimize seller engagement, and elevate the seller experience across the lifecycle journey.

You'll be responsible for building high-impact campaigns and programs through owned channels (email, in-product, SMS), while also shaping and enforcing the operational backbone of our lifecycle ecosystem— our governance and best practice frameworks that enable us to scale effectively. Your analytical and technical mindset will help you uncover insights, influence roadmap decisions, and design data-driven journeys that are both personalized and impactful.

This is a cross-functional role where you'll collaborate closely with Product Marketing, Product, Data Science, Engineering, Creative, and Marketing Operations to deliver seamless, automated lifecycle experiences.

You should be comfortable working autonomously, managing complex projects, and presenting insights to stakeholders and leadership. You bring strong marketing instincts, a deep understanding of marketing technologies, and a passion for improving customer experience at scale.

You Will

• Own and drive a cohesive lifecycle marketing strategy for your remit that aligns with broader go-to-market and team priorities
• Lead the planning, execution, and iteration of lifecycle campaigns and experiments across email, in-product messaging, and SMS
• Monitor dashboards to track lifecycle performance and KPIs and report on insights regularly
• Design and analyze A/B tests and experiments to drive continuous optimization
• Map ideal seller journeys and adoption paths, identifying high-leverage opportunities for engagement
• Create personalized, event-triggered journeys that deliver relevant content at the right moments
• Implement governance frameworks that ensure consistency, quality, and transparency across campaigns
• Collaborate with Data Science and Marketing Operations to define technical requirements for data-driven personalization
• Standardize lifecycle processes and documentation, making them scalable across teams
• Identify and prioritize infrastructure improvements, tooling gaps, and operational enhancements
• Champion best practices for segmentation, experimentation, and messaging strategy

You Have

• 8+ years of experience in lifecycle, CRM, or retention marketing, ideally in a complex, multi-product environment
• Deep understanding of customer journeys, segmentation, and automation strategy
• Strong analytical skills with experience using data to inform decisions and optimize programs
• Proven ability to plan and execute multi-channel marketing programs from concept through analysis
• Experience managing lifecycle campaigns in platforms like Braze, Iterable, or similar ESPs
• Familiarity with CRM and CDP tools such as Salesforce and Segment
• Strong business acumen and fluency in core marketing metrics like LTV, churn, and incrementality
• Excellent communication and storytelling skills, with the ability to influence cross-functional stakeholders and leadership
• Exceptional project management and organizational skills; capable of managing multiple workstreams independently
• Comfort navigating ambiguity and working in a fast-paced, evolving environment
