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!

We have an opening for a Principal Growth Product Manager to lead experimentation across activation and monetisation 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 monetisation 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.

• Own Growth Experimentation:
  Design, launch, and scale continuous experiments across activation and monetisation 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 behaviour and business performance.
• Prioritise and Balance Growth Bets:
  Continuously evaluate and prioritise a portfolio of growth opportunities ranging from rapid‑iteration experiments to larger strategic initiatives. Balance speed, impact, technical complexity, and learning potential to maximise 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 behaviour.
• Optimise for Mobile‑First Customer Behaviour:
  Help modernise and optimise activation and monetisation 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, prioritisation, and decision‑making. Explore opportunities to apply AI‑driven personalisation, targeting, and optimisation tactics across activation and monetisation experiences.
• Influence Monetisation & Lifecycle Strategy:
  Contribute to broader growth initiatives including packaging, pricing, lifecycle optimisation, and expansion strategy. Partner with Finance, Rev Ops, Analytics, and leadership to validate opportunities through experimentation and customer behaviour data.
• Collaborate Across Functions:
  Work closely with Engineering, Design, Data & Analytics, Finance, and Rev Ops to prioritise opportunities, improve instrumentation, and ensure experiments are measurable, scalable, and operationally sound.

• 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, monetisation, retention, or lifecycle growth and have a track record of driving business impact through experimentation.
