Staff Product Manager - E-Commerce Web Upper Funnel [CDI]

Location: Paris or Lille, France

Team: Decathlon E-Commerce Web - Upper Funnel scope

About the team

At the heart of Decathlon's global digital ecosystem, our E-Commerce Web team shapes the online destination of millions of sports enthusiasts around the world. The Upper Funnel scope is the entry point of our digital experience: from the homepage and category navigation, to product discovery via the search engine, AI recommendations, conversational commerce, Retail Media spaces and inspiration content. Our mission is to smoothly guide every user from inspiration to purchase intent.

Joining this high-traffic Web Product organisation means working at very large scale, where speed, discovery excellence, SEO, targeted monetisation and next-generation personalised journeys drive our daily business impact.

YOUR FUTURE CONTRIBUTION

As Staff Product Manager - Upper Funnel, you will bring the strategic vision, functional architecture and product leadership needed to take the discovery and exploration experience of our web platform to the next level. With full autonomy, you will tackle complex challenges: search performance, catalogue structuring, Retail Media integration and AI technology shifts (conversational interfaces, autonomous agents).

Your responsibilities revolve around 4 strategic pillars:

1. Strategic alignment, stakeholder management & Upper Funnel vision

• Driving the overall vision of discovery & engagement: Define and steer the strategic roadmap of the Upper Funnel touchpoints (Homepage, Category/listing pages, Search engine, Site structure/Taxonomy, Retail Media ad placements, Conversational assistants and Inspiration hubs).
• Executive & cross-functional alignment: Work closely with global business leadership, merchandising managers, SEO specialists, Retail Media monetisation teams and AI technology teams to align the organisation with the major evolutions of the platform.
• Steering macro metrics & funnel performance: Track and optimise the key metrics along the journey: organic/direct traffic, search CTR, browsing depth, conversational engagement rate, advertising yield (eCPM), bounce rate, CTR to product detail pages (PDP) and overall top-of-funnel conversion.

2. Functional architecture & Orchestration of the Web ecosystem

• Principal Functional Architect: Define the division of scope between the web squads (Search & Conversational Discovery, Taxonomy & Merchandising, Personalization/Recommendations, Retail Media & Sponsored Listings) in order to eliminate friction and duplication.
• Close collaboration in a Triad: Work in synergy with the Staff/Principal Web Engineers and Staff UX/UI Designers to align frontend performance (Core Web Vitals), the web Design System, micro-frontend architecture, conversational UI components and search/ad-serving APIs.
• Omnichannel journeys & smooth handover: Ensure smooth transitions from external acquisition channels to the web Upper Funnel, balancing organic discovery, conversational/agentic assistance and sponsored inventory, while facilitating the transition to the lower funnel (PDP, Basket & Checkout).

3. Strategic sparring & Product De-risking

• Strategic partner and mentor: Advise the Group Product Managers (GPM) and Product Managers (PM) of the web E-Commerce domain to navigate complex search algorithms, LLM agent architectures, ad-server integrations and very high-volume web constraints.
• De-risking strategies: Formulate and run rapid validation loops on high-uncertainty concepts (visual/voice search, conversational product advisors, agentic replenishment/bundles, sponsored placements).
• Continuous large-scale experimentation: Lead A/B testing and multivariate testing strategies at high traffic, balancing the intensity of conversational interactions and advertising pressure against organic conversion (CRO frameworks, Opportunity Solution Trees - OST).

4. Raising the culture & modern Web capabilities

• AI, Agentic & Monetisation leadership: Promote the adoption of cloud-native AI solutions (e.g. Google Vertex AI), conversational frameworks, agentic purchasing modes and Retail Media features to amplify both user experience and platform revenue.
• Raising Product practices: Support the PM community towards modern web best practices (continuous discovery frameworks, technical web performance optimisation, data-driven decisions).
• Impact multiplier: Raise the collective level of the Product organisation as an opinion leader, without direct line management responsibility.

WHAT YOU BRING

• Large-scale E-Commerce Web experience (7+ years): Solid Product Management track record in scaling high-traffic web e-commerce platforms (Upper Funnel, Search, Merchandising or Navigation).
• Upper Funnel & SEO expertise: In-depth understanding of top-of-funnel mechanics, technical SEO, internal search engines, taxonomy structuring and conversion rate optimisation (CRO).
• Mastery of Discovery & Analytics: Advanced practice of web analytics (GA4/Amplitude/Contentsquare), high-volume A/B testing, qualitative/quantitative user research and Opportunity Solution Trees (OST).
• Functional architecture: Ability to break down complex catalogue, ad-tech and AI/search challenges into clear execution strategies (MVP/V0/V1).
• Executive communication: Excellence in translating complex search/agentic architectures, Retail Media revenue issues and UX metrics into concise presentations for executives.
• Key technological assets & skills (Pluses):
• Google Vertex AI: Hands-on experience with Google Vertex AI (for Search, Recommendations or deploying ML/LLM models) is a major asset.
• Conversational & Agentic E-Commerce: A good understanding or experience of conversational AI interfaces (chat/voice) and agentic commerce concepts (autonomous intent resolution, task-oriented AI agents) is a strong plus.
• Retail Media & Monetisation: Experience with Retail Media concepts and ad management (sponsored products, ad-server integration, yield vs UX trade-offs) is a real plus.
• Attitude & Leadership: Strong influence without hierarchical authority, ability to thrive in ambiguity, collaborative Triad mindset and empathy in mentoring more junior PMs.
