• 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.
