Wallapop is a Barcelona based scale-up driven by the purpose to empower people to embrace a more conscious and human way of consumption. We believe in a world where collaborative economy is mainstream. This is what drives us.

Wallapop operates in Spain, Italy and Portugal, offering a catalogue of several hundreds of millions of products and services. Powered by technical innovation and continuous improvement, we bring together the scale & trust of classifieds with the marketplace’s convenience & reach. Our mission is to enable a connected trade ecosystem, making 2nd-hand the norm through smart use of technology.

The Challenge

As a Growth Product Manager, you’ll play a key role in accelerating Wallapop’s user growth by owning the strategy and roadmap for acquisition and activation. You’ll collaborate with engineers, designers, analysts, and marketing specialists to optimize the user journey from signup to the first 3 successful transactions. You’ll drive product-led growth through data-driven experimentation, improving funnel conversion, and aligning closely with our marketing teams across paid and organic channels.

What You Will Do

• Lead the growth strategy for user acquisition and activation across Wallapop’s app and web platforms.
• Design, run, and analyze experiments to improve engagement at every stage of the journey — from registration to the first transaction.
• Collaborate cross-functionally with engineering, design, data, and marketing to deliver high-impact growth initiatives.
• Partner with the Head of Acquisition to align marketing performance (SEO, SEM, Google Shopping) with in-product experiences that drive long-term activation.
• Leverage data and insights to identify and remove friction points in the onboarding and listing/buying flows.
• Define and monitor key metrics including activation rate, conversion rate, cost per activated user, and repeat transaction rate.
• Cultivate a culture of experimentation, utilizing A/B testing, cohort analysis, and iterative product improvements.
• Communicate learnings and results across product, marketing, and leadership teams to ensure shared goals and transparent progress.

What We’re Looking For

• Experience: Extensive experience in Product Management, with a focus on growth, activation, or conversion optimization.
• Experimental Mindset: A proven track record of driving measurable growth through data-informed experimentation and journey optimization.
• Analytical Depth: A strong analytical mindset with a comprehensive understanding of growth metrics and lifecycle flows.
• Collaborative Leadership: Experience working effectively within cross-functional teams of engineers, data scientists, designers, and marketers.
• Marketing Fluency: A solid understanding of how organic and paid channels (SEO, social, app campaigns) intersect with the product experience.
• Communication: Excellent storytelling skills; the ability to influence and align stakeholders around data-driven decisions.
• Tooling: Familiarity with A/B testing tools and analytics platforms (such as Amplitude, Mixpanel, or Looker).
• Mission-Driven: A genuine interest in marketplaces, user behavior, and sustainable consumption.

What Would Be A Plus

• Experience in marketplace or e-commerce environments, especially involving supply/demand dynamics.
• Technical background or a high degree of comfort collaborating closely with engineering teams on architectural trade-offs.
• Understanding of user segmentation, CRM automation, or retention marketing.
