About the Role

As our Lifecycle Marketing Lead, you'll be both a hands-on operator and the strategic owner of Prosper's most important unowned growth lever, building the system that scales it. As we expand to four products and surpass $60M ARR, lifecycle marketing is becoming increasingly critical to how clients discover, engage with, and stay connected to Prosper.

You'll define and own the end-to-end client journey across email, SMS, and future lifecycle channels. You'll combine data, experimentation, customer psychology, and thoughtful messaging to improve scheduling, retention, cross-sell, and reactivation outcomes. You'll build the systems, segmentation strategies, and testing infrastructure that transform lifecycle from a collection of campaigns into a strategic growth engine.

This is a unique opportunity at the intersection of rapid company growth, a cultural movement around neurodiversity and autism, and significant ownership over a highly visible business function. You'll be Prosper's first dedicated lifecycle marketing hire and the single owner responsible for how clients experience our brand across multiple products and touchpoints.

You'll thrive in this role if you're equal parts strategist and operator. You think in customer journeys rather than individual campaigns, love using data to inform decisions, and are energized by understanding what motivates people to take action. You're comfortable navigating ambiguity, collaborating across teams, and building systems that make customer experiences more thoughtful and effective over time.

You Will

• Own Prosper's lifecycle marketing strategy. Define how we communicate with clients throughout their journey across all Prosper products. Establish a cohesive lifecycle strategy spanning lead-to-schedule, schedule-to-onboarding, retention, cross-sell, and reactivation, ensuring every interaction contributes to a seamless client experience.
• Design and execute structured experimentation. Build and manage a rigorous testing roadmap focused on business outcomes. Develop hypotheses, design A/B tests, establish success metrics, and translate learnings into scalable improvements across the customer journey.
• Operate and optimize our lifecycle platform. Own Customer.io and the infrastructure behind lifecycle communications. Build and maintain flows, segments, triggers, suppressions, and personalization logic while ensuring deliverability, compliance, and data integrity.
• Analyze and optimize. Track performance across key lifecycle metrics, including conversion, retention, engagement, attach rates, and reactivation. Use quantitative analysis and customer behavior insights to identify opportunities and prioritize the highest-impact initiatives.
• Create compelling customer communications. Write thoughtful, high-performing email and SMS copy that reflects Prosper's brand and mission. Use behavioral psychology, customer insights, and testing results to continuously improve messaging effectiveness.
• Build systems and processes. Develop the dashboards, operating rhythms, segmentation frameworks, and testing infrastructure that allow lifecycle marketing to scale efficiently as Prosper grows.
• Partner across the organization. Work closely with Engineering, Clinical Operations, Product, and Marketing to improve the customer experience, ensure data quality, support product launches, and drive cross-functional initiatives.

About you

• 5–8 years of experience in marketing, growth, or related disciplines, including at least 2 years focused on lifecycle marketing. Experience developing and executing lifecycle strategies that drive customer engagement, retention, and long-term value.
• Hands-on lifecycle platform expertise. You've built and managed production workflows in platforms such as Customer.io, Braze, Iterable, or Klaviyo, including segmentation, triggers, experimentation, and personalization.
• Strong analytical foundation. You're comfortable working with data in Excel, Google Sheets, and ideally SQL. You can analyze customer behavior, size opportunities, and translate insights into action.
• Customer journey thinker. You naturally think in systems and experiences rather than isolated campaigns. You obsess over the client perspective and identify friction points throughout the lifecycle.
• Exceptional ownership. You are the trusted owner of a complex function end-to-end: copywriting to longterm strategy. You are the person who knows the status of every flow, test, segment, and metric, and also where we want our customer journey to be in a year.
• Strong experimentation mindset. You know what to prioritize, what to deprioritize, and how to use data to learn, iterate, and drive continuous improvement.
• Thoughtful copywriter. You enjoy writing email and SMS copy yourself and have strong instincts for messaging, hooks, and behavioral psychology.
• Technical curiosity. You have a strong understanding of the data, systems, and operational mechanics behind lifecycle marketing. You're comfortable working across event data, segmentation, personalization logic, deliverability, and regulated communications, and can translate technical complexity into effective programs.
• Cross-functional operator. You work effectively with Engineering, Product, Clinical Operations, and Marketing partners to drive outcomes and solve problems.
• Builder mindset. You're excited by the opportunity to establish lifecycle marketing as a core growth function and build systems that will scale alongside the business.
• Mission-driven. You care deeply about improving access to care and want your work to have a meaningful impact on autistic and neurodivergent adults.
