Growth Product Manager (Principal)

Constant Contact • Boston, MA

21h • $159,500 - $191,400 • Hybrid

About The Position

Constant Contact is seeking a Principal Growth Product Manager to lead experimentation across activation and monetization. This role is metric-driven, focusing on learning velocity, experimentation quality, and measurable improvements in key business metrics. The successful candidate will join a high-performing growth organization, working within dedicated squads to run approximately 20 experiments per month across various customer journey stages. The team operates with an AI-native rhythm, emphasizing fast iteration, rigorous measurement, and continuous learning. The ideal candidate is adept at experimentation, moves quickly, thinks statistically, and is motivated by shipping iterative tests that yield measurable business outcomes.

Requirements

• 8+ years of Product Management experience, with significant experience in Growth Product Management within SaaS, subscription, or consumer-oriented products.
• Owned metrics across activation, monetization, retention, or lifecycle growth and have a track record of driving business impact through experimentation.
• 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.
• 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.
• 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.
• Understand the opportunities and constraints of mobile customer experiences and can simplify complex workflows into intuitive user journeys across devices.
• 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.
• Collaborate effectively across Product, Engineering, Design, Analytics, Finance, and RevOps. You communicate clearly, influence without authority, and can align teams around measurable business outcomes.

Responsibilities

• 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.
