Senior Growth Product Manager - Ruby Labs

About Us

Ruby Labs is a leading tech company that creates and operates innovative consumer products. We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us.

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.

Benefits

• Remote Work Environment: Embrace the freedom to work from anywhere within ±4 hours of CET.
• Unlimited PTO: Take time to recharge and prioritize your well-being without counting days.
• Paid National Holidays: Celebrate and relax on national holidays with paid time off.
• Company-provided MacBook: Top-notch Apple MacBooks provided to team members.
• Flexible Independent Contractor Agreement: Autonomy, tax advantages, and flexibility under an independent contractor model.
