Sur une stack Angular (Front) / Node.js (Back/BFF), le développeur Senior se verra confier des missions stratégiques et techniques très précises : Vos missions ? 1. Développement d'Applications et de "Parcours" Bancaires Côté Front (Angular 14+) : Concevoir des interfaces dynamiques, fluides et responsives pour les nouveaux parcours (ex: souscription de crédit en ligne, ouverture de compte, outils d'aide à la vente pour les conseillers).

Pratiques Agiles et Collaboratives Évolution dans un cadre Agile à grande échelle (SAFE / Scrum). Collaboration étroite avec les Product Owners (PO), Tech Leads, Architectes et les UX/UI Designers du chapitre.

HTML development and design are the two main skill areas of the front end. Design falls under the web designer's domain, and as for development, that's handled by the front-end developer. The designer creates graphic mockups with specialized software tools such as Photoshop, and it's up to the front-end developer to translate the graphic mockup into a functional mockup by manipulating code. In simple terms, the web designer draws, the developer formalizes using programming languages like HTML and CSS. Some developers are capable of working with JavaScript. But most of the time, the developer uses their preferred software for all their projects. Previously, development was limited to the back end. But today, more and more designers are starting to take an interest in development. The front-end developer often comes from a web design background.
