Ce qu’il faut savoir sur React

React est une bibliothèque JavaScript open-source, développée par Meta (anciennement Facebook), utilisée pour construire des interfaces utilisateur dynamiques et réactives. Elle repose sur une approche basée sur les composants, permettant de créer des éléments réutilisables pour développer des applications web complexes. React utilise un DOM virtuel pour optimiser les performances en minimisant les mises à jour directes du DOM réel. Compatible avec de nombreux outils et frameworks, React est particulièrement apprécié pour sa flexibilité, sa gestion efficace de l'état via des librairies comme Redux, et son écosystème riche. C'est un choix privilégié pour les développeurs cherchant à créer des applications modernes et interactives.

Vos principales responsabilités seront les suivantes : Reprendre la responsabilité opérationnelle de l'infrastructure AWS, entièrement administrée avec Terraform, sans ClickOps. Maintenir et faire évoluer l'environnement Kubernetes, Docker et Helm, tout en évaluant avec pragmatisme si Kubernetes reste la solution la plus adaptée à la taille de la plateforme. Simplifier et rationaliser les pipelines CI/CD construits autour de GitLab self-hosted et Helm. Identifier, chiffrer et mettre en œuvre des leviers d'optimisation des coûts cloud. Faire progresser l'observabilité, la documentation et les runbooks afin de renforcer la fiabilité et l'autonomie des équipes. Contribuer aux sujets de sécurité opérationnelle : gestion des secrets, RBAC, moindre privilège et réponses techniques aux audits clients. Les chantiers des 12 à 18 prochains mois sont concrets et ouverts : rationalisation de la CI/CD, optimisation des coûts AWS, réflexion sur une architecture plus simple que Kubernetes, renforcement de l'observabilité et éventuelle mise en place d'une approche GitOps avec Argo CD ou une solution équivalente. Vous recevez les besoins par trois canaux : le CPTO pour les sujets d'infrastructure, de stratégie et de sécurité ; les leads lors des temps d'amélioration continue ; et les développeurs au quotidien. Les sujets sont cadrés collectivement, mais leur mise en œuvre vous appartient. Vous êtes intégré·e au produit, pas positionné·e dans un silo infrastructure. Environnement technique : AWS, Terraform, Kubernetes, Docker, GitLab self-hosted, Helm, Kuma, PHP/Symfony, React et TypeScript. La plateforme connaît un rythme régulier d'une mise en production par sprint et de plusieurs dizaines de correctifs. Le SLA contractuel est de 98 % minimum, sans pics saisonniers et sans astreintes. Conditions proposées : rémunération fixe entre 60 000 € et 75 000 € selon expérience, complétée par environ 5 000 € de participation. Vous bénéficiez également de tickets restaurant, d'une mutuelle Alan et d'un MacBook avec configuration au choix. Le poste est basé à Levallois-Perret, avec deux jours de présence sur site et trois jours de télétravail par semaine. Le processus de recrutement comprend un échange RH, un entretien avec le CPTO, puis une rencontre avec les leads.
