• Identifier et exécuter des améliorations dans la base de code pour permettre aux humains et aux agents d'IA de progresser rapidement et de livrer du code en toute sécurité. • Travailler avec un groupe d'ingénieurs seniors dans un environnement de travail fluide (*low-process*), axé sur la confiance et l'autonomie. • Orienter les décisions et obtenir des consensus de manière asynchrone grâce à une documentation et des spécifications soignées. • Prendre en charge les fonctionnalités de bout en bout — des systèmes backend jusqu'à l'interface client des partenaires. Vous travaillerez principalement sur le backend, mais vous devrez utiliser des outils d'IA pour naviguer sur l'ensemble de la stack au besoin. Ce qui nous importe, c'est votre capacité à livrer une fonctionnalité complète, et non votre capacité à écrire du code React de calibre production de mémoire. • Concevoir des solutions évolutives et des modèles fondamentaux qui nous permettent de lancer efficacement de nouvelles expériences partenaires. • Travailler directement avec les gestionnaires de produits (PM) et les partenaires d'affaires pour définir et affiner notre feuille de route (*roadmap*). Votre voix et votre vision technique comptent. • Collaborer avec une équipe diversifiée, en donnant et en recevant des commentaires constructifs pour favoriser votre développement.
