About the role:

We’re looking for a Product Manager to lead our Growth Engineering initiatives - helping more new users activate, convert, and stay retained.

You’ll own the end-to-end activation funnel, working closely with engineering, design, and data to identify friction points, run experiments, and build scalable improvements. The ideal candidate has a strong analytical mindset, enjoys solving ambiguous growth problems, and can move quickly from insight to shipped impact.

What you will do:

• Own the activation funnel from signup to retained usage, identifying key drop-off points and opportunities for growth.
• Design and execute A/B experiments that improve onboarding, reduce churn, and increase conversion.
• Partner with engineering to prioritize and ship high-impact experiments efficiently.
• Collaborate with design to improve clarity, navigation, and overall user experience in early journeys.
• Work with data to build dashboards and measure both leading and lagging indicators of growth.
• Help align growth initiatives with broader company goals, including ARR and long-term retention.
• Build a repeatable experimentation framework that can scale across teams.

Who You Are:

• 4+ years of product management experience, ideally in growth, activation, or SaaS roles.
• Comfortable working in data-informed and experiment-driven environments.
• Experienced collaborating with engineers on iterative experiments and technical product areas.
• Analytical thinker with a strong sense of ownership and curiosity about user behavior.
• Able to balance quantitative metrics with qualitative insights to guide decisions.
• Skilled at communicating priorities and results across cross-functional teams.
• Experience with tools such as Lookr, Eppo etc.

What Success Looks Like:

• A measurable increase in activation rate and onboarding engagement.
• A clear understanding of user archetypes and targeted experiences for each.
• Faster iteration cycles and a well-defined framework for testing and learning.
• Demonstrated improvement in conversion, retention, and long-term customer value.
