Growth Product Manager (Principal)

At Constant Contact, we are seriously awesome people who take ownership and make an impact by operating with the mindset, integrity and courage of a small business owner. There’s something so profoundly rewarding about knowing that your work is empowering people everywhere to pursue their dreams.  Here, we all play an integral part in helping business owners, entrepreneurs, non-profits and individuals to succeed by giving them all the help and tools they need to grow online. We’re energized by new challenges and new possibilities-and we’re just getting started!Principal Growth Product Manager, Activation & Monetization We have an opening for a Principal Growth Product Manager to lead experimentation across activation and monetization at Constant Contact. This is not a traditional roadmap-driven Product Management role. You will operate as a metric owner first, not as a feature owner. Success in this role comes from learning velocity, experimentation quality, and measurable movement in activation, conversion, retention, and expansion metrics. You’ll join a high-performing growth organization made up of two Principal Growth PMs (this role would be the third) working across two dedicated squads with 6 and 4 engineers. Together, the team runs approximately 20 experiments per month across onboarding, upgrade flows, lifecycle experiences, and monetization surfaces. We operate with a highly autonomous, AI-native rhythm focused on fast iteration, rigorous measurement, and continuous learning. The ideal candidate thrives in experimentation environments, moves quickly, thinks statistically, and is energized by shipping iterative tests that drive measurable business outcomes. What You’ll Do Own Growth Experimentation: Design, launch, and scale continuous experiments across activation and monetization surfaces including onboarding flows, paywalls, upgrade experiences, trial-to-paid conversion, and retention journeys. Define hypotheses, success metrics, and decision criteria to drive measurable improvements in customer behavior and business performance. Prioritize and Balance Growth Bets: Continuously evaluate and prioritize a portfolio of growth opportunities ranging from rapid iteration experiments to larger strategic initiatives. Balance speed, impact, technical complexity, and learning potential to maximize business outcomes and team velocity. Lead with Speed and Autonomy: Operate as a leader within a highly autonomous growth squad. Move quickly from insight to experiment, balancing rigor with execution speed. You are comfortable making decisions with imperfect information, iterating rapidly, and refining based on data and customer behavior. Optimize for Mobile-First Customer Behavior: Help modernize and optimize activation and monetization experiences for a mobile-first customer base. Identify friction points and opportunities across acquisition, onboarding, upgrade, and retention flows to create seamless cross-device experiences. Leverage AI to Accelerate Growth: Use AI tools and workflows to improve experimentation velocity, analysis, prioritization, and decision-making. Explore opportunities to apply AI-driven personalization, targeting, and optimization tactics across activation and monetization experiences. Influence Monetization & Lifecycle Strategy: Contribute to broader growth initiatives including packaging, pricing, lifecycle optimization, and expansion strategy. Partner with Finance, RevOps, Analytics, and leadership to validate opportunities through experimentation and customer behavior data. Collaborate Across Functions: Work closely with Engineering, Design, Data & Analytics, Finance, and RevOps to prioritize opportunities, improve instrumentation, and ensure experiments are measurable, scalable, and operationally sound. Who You Are A Growth Product Leader: You have 8+ years of Product Management experience, with significant experience in Growth Product Management within SaaS, subscription, or consumer-oriented products. You’ve owned metrics across activation, monetization, retention, or lifecycle growth and have a track record of driving business impact through experimentation. Fluent in Experimentation: You have deep experience designing and evaluating experiments, including hypothesis development, A/B testing methodologies, sample sizing, statistical significance, novelty effects, instrumentation quality, and interpreting ambiguous or conflicting results. You think in funnels, cohorts, and behavioral data. Outcome-Oriented: You optimize for measurable outcomes over roadmap output. You’d rather launch multiple well-instrumented experiments this month than spend a quarter designing the perfect framework. You value rapid learning, iteration, and continuous optimization. Highly Analytical: You are deeply comfortable using data to identify opportunities, validate hypotheses, and make decisions. You understand metrics such as activation, conversion, retention, expansion, attach rate, LTV, churn, and trial-to-paid performance, and know how to translate data into action. Mobile & Customer Minded:  You understand the opportunities and constraints of mobile customer experiences and can simplify complex workflows into intuitive user journeys across devices. AI-Native and Curious: You actively leverage AI tools to accelerate workflows, improve decision-making, and increase team efficiency. You are excited about how AI can enhance personalization, experimentation, and customer growth. A Strong Cross-Functional Partner: You collaborate effectively across Product, Engineering, Design, Analytics, Finance, and RevOps. You communicate clearly, influence without authority, and can align teams around measurable business outcomes. How We Work We optimize for outcomes over output. We value fast learning over perfect planning. We run high-velocity experiments and iterate quickly. We care deeply about instrumentation quality and measurement rigor. We use AI tools aggressively to accelerate executi
