Overview 

We are rebuilding our customer-facing applications from the ground up. Today, our applications are primarily built with a legacy Spring Boot + Thymeleaf architecture. Our goal is to evolve to a modern, scalable front-end platform that separates the user experience from backend services and embraces modern DevSecOps practices.  

We're looking for an experienced React engineer who can help lead this transformation. This is not a maintenance role—it is an opportunity to define the architecture, engineering standards, and development practices that will power our next generation of applications.  

You'll work closely with architects, backend engineers, DevOps, security, and product teams to build fast, secure, maintainable web applications while establishing best practices across the organization.
