About the role
We are looking for a results-driven Senior Growth Product Manager for one of our core D2C subscription products. You will work on a single product and be fully responsible for increasing ARPU through higher product value: delivering winning tests in the post-purchase experience that make the product more valuable for each user.
You will own the full cycle from research to a proven result and report to the Head of Growth, with AI tooling as a core part of your workflow. The bar is high and so is the upside - strong results are significantly rewarded, with a proven path to career growth.
Key Responsibilities
Research & Competitor Insights: Find where users miss value and why they leave, using product and historical data, user feedback, and competitor analysis.
Hypothesis Pipeline: Turn those insights into a continuous, prioritised backlog of product ideas, each backed by evidence and a clear expected impact.
Product Value: Grow ARPU by giving users more value after purchase: improve onboarding, core features, and the moments where users decide whether the product is worth keeping.
Specs & Delivery: Write clear, testable specs and work daily with engineering so every test ships fast and works as intended.
Growth Collaboration: Coordinate with the CRO and data teams so product and funnel tests run in sequence and every result is read correctly.
Test Wins: Deliver a steady stream of A/B test winners on post-purchase metrics, with ARPU as the main one, and raise the share of tests that win over time.
Qualifications
Product Management: 3+ years in product growth roles on D2C subscription or consumer products (web-to-web, web-to-app, mobile apps) or similar markets.
Proven Wins: A track record of A/B tests or product changes that measurably grew revenue, with results you can attribute to your own work.
User Journey & Product Sense: Strong understanding of consumer user journeys and of what turns a first purchase into lasting value for the user.
Research & Analytics: Hands-on user research, competitor analysis, and product analytics (Mixpanel or a close equivalent) to build the evidence behind every idea.
Experimentation: Experience designing and interpreting A/B tests, including significance, sample size, and test duration.
AI Tooling: Active daily use of AI tools (Claude or equivalent) to accelerate concept, analysis, and prototype work, especially UI/UX design of experiments.
Lifecycle Experience: Experience with subscription onboarding, engagement, or cancellation flows is a bonus.
Leadership Attributes
Results-driven - measures their own work by test wins and revenue impact
Evidence-led - backs every idea with data, user research, or competitor proof
Ownership mentality - treats the product as their own: proposes, prioritises, and drives ideas to a result
Bias for action - makes sound decisions quickly and iterates fast
Communicates with clarity - explains ideas and results in writing so they can be reviewed without a meeting
