We are seeking a highly capable JavaScript Full-Stack Developer with a passion for building rich, responsive web and hybrid-mobile applications. In this role, you will leverage your expertise in JavaScript/TypeScript, React, and Next.js to deliver fast, SEO-friendly, and mobile-first user interfaces.

You will focus on crafting exceptional web experiences that look and feel like native mobile apps, optimizing performance for both desktop and mobile web view browsers (including iOS Safari). Working closely with backend engineers, UX designers, and product owners, you will translate interactive designs into clean, modular, and reusable front-end code.

Responsibilities
  • Design and build high-performance, responsive web applications using React and Next.js (utilizing features like SSR, SSG, and API routes)
  • Implement pixel-perfect, mobile-first designs that adapt seamlessly across devices, with a specific focus on optimizing layouts, animations, and touch interactions for mobile viewports (including iOS/Android browsers)
  • Manage complex client-side state (e.g., Redux, Zustand, Context API) and integrate applications with backend RESTful or GraphQL APIs
  • Profile and optimize applications for maximum loading speed, Core Web Vitals, and smooth rendering on lower-powered mobile devices
  • Write clean, maintainable, and testable JavaScript/TypeScript. Conduct thorough code reviews and contribute to our shared UI component library
Requirements
  • 2+ years of proven experience in modern web development with a strong focus on building user-facing features
  • Advanced knowledge of JavaScript (ES6+), TypeScript, and React
  • Practical experience with the Next.js framework (App Router or Pages Router, Server Components)
  • Familiarity with modern CSS frameworks or methodologies (e.g., Tailwind CSS, styled-components, CSS Modules)
  • Experience in optimizing web apps for mobile browsers, PWAs (Progressive Web Apps), or integrating web views within hybrid mobile containers
  • Experience with Git and working in an Agile/Scrum development cycle
  • Minimum English language level of B1+
