Bigblue

📍Paris | CDI | Français 🇫🇷 & Anglais 🇬🇧 courants requis Le e-commerce explose — mais les marques indépendantes galèrent encore à offrir une logistique aussi fluide que celle d’Amazon. Chez Bigblue, on veut changer ça. Notre mission : aider les marques à scaler plus vite tout en offrant une expérience client cinq étoiles, grâce à des opérations logistiques au top. Depuis 2018, on construit une plateforme tech qui propulse déjà 500+ marques — de jeunes pépites DTC aux grands noms comme MUJI, Aigle ou Cabaïa. Avec plus de 110 Bluebigs à Paris, Madrid et Londres, notre propre WMS Atlas et un réseau de 7 entrepôts en Europe, on s’attaque à des défis logistiques que d’autres n’osent même pas regarder. Résultat : une logistique plus rapide, plus intelligente, et plus verte. Boostés par plus de 20 M$ de financement et choisis par les futurs leaders du e-commerce, on passe à la vitesse supérieure : 10 millions de commandes traitées en 2024… et ce n’est que le début. L’aventure s’annonce ambitieuse — et on cherche les bons talents pour écrire la suite avec nous.
