Sr Front-End Developer (React) – Advanced English Level

We are seeking a Senior Front-End Developer with advanced English proficiency to join our team in Buenos Aires, Argentina, for a digital transformation project. This role involves developing microservice front ends for rapid feature deployment and integrating multiple Digital and Operations platforms.

Responsibilities

• Design, develop, and enhance highly interactive front-end applications using React, Next.js, and TypeScript within a modern AI-driven ecosystem.
• Build personalized user experiences that leverage LLM APIs and user-context data to deliver intuitive AI recommendations and dynamic content experiences.
• Collaborate closely with cross-functional teams within the AI COE to integrate APIs, AI services, and agentic solutions developed across multiple platforms.
• Contribute to the architecture and technical direction of a rapidly evolving product where requirements may be fluid and discovery-driven.
• Partner with technical leadership to evaluate, prototype, and implement innovative solutions in ambiguous or incubation-stage environments.
• Develop scalable UI components, API integrations, and orchestration layers that support real-time interactions and intelligent workflows.
• Ensure high engineering standards through automated testing, code reviews, and implementation of code quality and security best practices.
• Participate actively in Agile ceremonies and collaborate with product, engineering, and AI stakeholders to continuously refine and improve the platform experience.
• Leverage modern development tools, CI/CD pipelines, and AI-assisted engineering solutions to improve delivery speed and maintainability.
• Operate as a proactive problem solver capable of independently driving solutions, making technical recommendations, and adapting quickly to evolving business needs.

Requirements

• Required Technical Skills
  • 5+ years of hands-on experience with TypeScript, React, and Next.js, with strong technical depth in Front-End architecture and API orchestration.
  • Proven ability to design and build dynamic, real-time user interfaces that react to streaming data and user-specific context.
  • Strong understanding of React 17+ component lifecycles, hooks, and modern state management solutions such as Redux, Context API, and RTK Query, including when and how to apply each effectively.
  • Experience building scalable UI solutions and integrating with REST APIs using modern frameworks and languages such as Node.js or Ruby on Rails.
  • Ability to work in highly collaborative Agile environments where requirements evolve quickly and engineers are expected to help shape the technical direction, not just execute predefined tasks.
  • Strong problem-solving mindset with the creativity and initiative to connect systems and APIs developed across multiple teams.
  • 3+ years of experience building robust unit, component, and end-to-end automated tests using frameworks such as Jest, Vitest, React Testing Library, Cypress, or Playwright.
  • Experience implementing and maintaining code quality and security enforcement tools, including SonarQube, Fortify, Nexus IQ, or similar platforms.
  • Familiarity with CI/CD and cloud tooling such as Jenkins, CloudBees, UrbanCode Deploy, AWS, and PCF environments.
  • Experience leveraging AI-assisted development tools such as GitHub Copilot, Atlassian Rovo, or similar technologies to improve engineering productivity and integration workflows.
