The posting

At CI&T, we help large enterprises transform the potential of AI into real business impact with AI Deployment, AI-native execution, and tech-integrated business solutions.

With 30 years of experience in technological transformation, we accelerate innovation with expertise in Agentic SDLC, Application modernization, Data & AI, Martech and Business strategy.

We are 8,000 CI&Ters across more than 25 countries, collaborating to build solutions with real impact. AI is already part of how we work, evolve, and innovate every day.

We’re looking for a Senior Frontend Developer to join a CI&T squad working on a financial services client. You’ll help move an established Java-based web application onto a modern React frontend: analysing legacy pages, turning them into a well-structured component library, and building fast, accessible user interfaces. You’ll work closely with backend developers, UX/UI designers, QA and the Product Owner.

What you’ll do - Build and maintain responsive, accessible user interfaces with React and TypeScript - Analyse legacy server-rendered pages and break them down into reusable React components - Grow and maintain a shared component library based on shadcn/ui - Connect the frontend to backend REST APIs: handle loading, error and empty states consistently - Write unit and component tests with Vitest/Jest and React Testing Library - Join refinement sessions: break features into tasks, estimate them and point out UX or technical risks - Review pull requests and help keep frontend standards, performance and documentation in good shape - Work with designers to turn designs into pixel-accurate, consistent interfaces

What you need (must-have) - Around 5 years of professional frontend experience, with at least 3 years in React (hooks, context, composition patterns) - Strong TypeScript, HTML5 and modern CSS skills - Hands-on experience with Vite: project setup, environment configuration and build optimisation - Experience with shadcn/ui and the tools beneath it, Tailwind CSS and Radix UI - Solid automated testing skills with Vitest and/or Jest, ideally with React Testing Library - Experience consuming REST APIs: authentication, error handling and pagination - Good grounding in web accessibility (WCAG) and responsive design - Experience with routing (e.g. React Router or TanStack Router) and form validation (e.g. Zod) - Familiarity with linting and formatting (ESLint, Prettier), Git workflows and CI/CD pipelines - Experience working in agile teams (Scrum or Kanban) - Good English communication skills for working with international stakeholders

Nice to have - Storybook, for documenting and developing components in isolation - Zustand, for client-side state management - TanStack Query, for server state, caching and data synchronisation - TanStack Form, for complex, type-safe forms - Analysing legacy pages (e.g. JSP, XSLT/XML-rendered or server-side templates) and restructuring them into React components - End-to-end testing with Playwright or Cypress - Design systems and design tokens, and working from Figma - Frontend performance work: Core Web Vitals, code splitting and lazy loading - Basic understanding of Java web backends and how they serve and secure the frontend - Experience in banking or other regulated environments

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
