• Qualité : TDD, JUnit 5, Testcontainers (clé pour sécuriser nos refontes), SonarCloud.
• À la marge : Scala/Spark (ETL), React (Front-end).

✨ Ce que tu apportes

• Expertise Java confirmée (7+ ans) : Bonne maîtrise du développement Backend, avec une capacité démontrée à structurer des logiques métier complexes et du code industriel durable.
• Maîtrise d'Elasticsearch : Tu sais tuner le moteur sous le capot pour des performances optimales en lecture et écriture.
• Expérience de la Refonte : Tu as déjà vécu la transformation d'un projet existant et tu maîtrises les patterns de migration (Strangler Fig, etc.).
• Mindset Engineering : Tu as une capacité démontrée à modéliser des problématiques métier denses pour les traduire en solutions techniques simples et pérennes.
• Pragmatisme : Tu sais arbitrer entre innovation technique et livraison de valeur continue.

💰 Ce que nous t'offrons

• Mode de travail hybride. 
• Cadre : Bureaux Decathlon Digital à Nantes (gare sud)
• Équipement : MacBook Pro ou Dell XPS de dernière génération
• Développement : Certifications Cloud (GCP), accès aux conférences (Devoxx, etc.), et temps dédié à la veille technique
• Package de rémunération attractif (participation des employés aux actions de l'entreprise, bonus mensuels/trimestriels)
• Vie d'équipe et Bien-être : de nombreux sports et défis ensemble et événements réguliers (afterworks, team buildings, triathlon par équipe) pour maintenir une excellente cohésion et un équilibre vie pro/perso optimal.
