• The role is critical to Ruby Labs’ mission of building innovative, consumer-led products, as the Growth Product Manager will be the primary driver of funnel performance, ensuring alignment between product design, user experience, and measurable growth outcomes.
• Define the concept, target audience, and positioning for your funnel by conducting market research, analyzing user behavior, and identifying high-potential segments to maximize conversion potential.
• Determine the optimal funnel structure before building begins, mapping out user journeys, drop-off points, and engagement triggers to design a logical, high-converting flow from awareness to action.
• Build the full acquisition funnel from scratch, including wireframes, user flows, and technical specifications, ensuring seamless integration between product, design, and engineering teams.
• Own copy, flow logic, and structure at every step of the funnel, crafting persuasive messaging, intuitive navigation, and psychological triggers that guide users toward desired actions while maintaining brand consistency.
• Prepare mockups and developer briefs that clearly communicate design intent, interaction patterns, and technical requirements to enable efficient implementation by engineering and design teams.
• Design the test — questions, answer options, and scoring logic — for personalized user assessments, ensuring validity, engagement, and actionable insights that feed into tailored product recommendations or outcomes.
• Participate in building the personalised results report (support provided), collaborating with designers and content specialists to deliver compelling, data-driven feedback that enhances user satisfaction and retention.
• Monitor funnel performance post-launch and drive continuous improvement by tracking key metrics, identifying bottlenecks, and iterating based on A/B test results and user feedback.
• Oversee creatives and maintain quality across the funnel, ensuring all visual, textual, and interactive elements align with brand standards and conversion goals.
• Be accountable for conversion, retention, and product quality, owning the full P&L impact of the funnel and reporting on ROI, CAC, ARPU, and LTV to stakeholders.
• Ruby Labs is a fast-growing tech company operating in the CET time zone, creating innovative consumer products across health, education, and entertainment industries, with a culture that values ambition, impact, and results-driven execution.
• The team operates with a high-velocity, ownership-driven mindset, where individuals are empowered to take initiative, experiment rapidly, and scale successful initiatives without bureaucratic delays.
• In this role, you will develop deep expertise in growth hacking, funnel optimization, and data-informed product decisions, gaining hands-on experience in end-to-end product ownership that translates directly to senior leadership opportunities.
• You will achieve measurable impact by scaling funnels that drive significant user acquisition and revenue growth, building a portfolio of proven growth strategies that enhance your professional credibility and market value in the product management space.

• 3–5 years of experience managing a full-stack team across product development and marketing, with demonstrated ability to lead cross-functional initiatives from concept to launch.
• Proven experience owning a web sales funnel end-to-end, including research, design, development, testing, and performance optimization.
• Strong knowledge of core marketing metrics such as conversion rate, customer acquisition cost (CAC), return on investment (ROI), and average revenue per user (ARPU).
• Hands-on experience collaborating closely with developers and designers to translate product visions into functional, user-centered experiences.
