Staff Digital Product Designer – E-Commerce / Web Platform
Department: E-Commerce & Customer Experience / Web Team
Level: Individual Contributor Lead (Staff Level)
Location: Lille / Paris
1. Context & Project
Decathlon's purpose is to bring people together through sport to make wellbeing accessible for all, guiding our overarching ambition to build a Local Human Bond and deliver accessible, unique sporting solutions globally. In this context, our goal is to build personalized, enriched experiences across all digital touchpoints and physical stores, leveraging Digital, Data, and AI to elevate the global customer journey.
The E-Commerce Web Challenge
As the digital front door for millions of sport practice enthusiasts around the globe, our web platform (decathlon.country) must seamlessly convert online curiosity into real-world sport experiences. Our challenge is to transform a massive, multi-category web store into an intuitive, frictionless digital portal.
We need to guide every user—from a first-time visitor searching for sports goods to a returning member—through a smooth journey that connects online browsing directly with local store availability, click-and-collect, and circular services like rentals and repairs.
By building a standardized, modular web experience, we equip country teams and international franchise partners with pre-validated, high-converting funnel journeys so they can scale local commerce effortlessly without rebuilding core web experiences from scratch.
Scope & Structure (4 Dedicated E-Com Squads)
- Acquisition: Turn global internet users into active visitors through high-converting landing experiences, SEO, campaign entry points, and personalized traffic onboarding.
- Navigation: Help users find the exact product or advice they need within a vast catalog through intelligent search, taxonomy, filtering, and catalog hierarchy.
- Decision: Give users every compelling reason to choose a product using rich product detail pages (PDP), media, sizing confidence, customer reviews, and circular/sustainability options.
- Conversion: Deliver frictionless checkout, flexible payment methods, order self-tracking, store pickup options, and effortless returns.

Beyond defining strategy, you lead hands-on experimentation, product de-risking, and rapid validation loops—ensuring high-stakes web features across Acquisition, Navigation, Decision, and Conversion are proven through A/B testing, CRO analysis, and real user data before global rollout. You align the 4 web squads around a unified web vision, accelerate commercial value delivery, and elevate design craft maturity across teams.
