Summary/Objective

We are seeking a highly skilled and experienced Senior React Developer to join our dynamic team. The ideal candidate will have a proven track record of designing, architecting, and delivering large-scale React applications using the latest development practices. You will play a key role in shaping the front-end architecture, ensuring optimal performance, and delivering high-quality, maintainable code. Additionally, you should have a keen eye for good user experience (UX), ensuring that the applications you build are not only functional but also intuitive and delightful for users. If you are passionate about building scalable, performant, and user-friendly web applications, we want to hear from you!

Essential Functions/ Responsibilities

Design, architect, and develop large-scale React applications using modern React practices (e.g., hooks, functional components, context API, etc.).
Optimize React applications for maximum performance, scalability, and maintainability.
Collaborate with cross-functional teams (designers, product managers, backend developers) to deliver high-quality features and solutions.
Write clean, reusable, and well-documented code following best practices.
Develop and maintain unit tests, component tests, and end-to-end (e2e) tests to ensure code quality and reliability.
Troubleshoot and debug issues, ensuring a smooth user experience.
Stay up-to-date with the latest trends and advancements in React and front-end development.
Mentor and guide junior developers, fostering a culture of learning and growth within the team.
Advocate for and implement user-centric design principles to ensure applications are intuitive, accessible, and visually appealing.

Required Qualifications

5+ years of professional experience in front-end development, with a strong focus on React.
Proven experience designing and architecting large-scale React applications.
Deep understanding of React build processes, including Webpack, Babel, and other related tools.
Strong knowledge of React performance optimization techniques (e.g., memoization, lazy loading, code splitting).
Solid understanding of web/internet basics (e.g., HTTP, REST APIs, browser rendering, security).
Experience writing comprehensive unit tests, component tests, and e2e tests using tools like Jest, React Testing Library, Cypress, or similar.
Proficiency in modern JavaScript (ES6+), HTML5, and CSS3.
Familiarity with state management libraries (e.g., Redux, Zustand, Recoil).
Experience with version control systems (e.g., Git).
Strong problem-solving skills and attention to detail.
Excellent communication and collaboration skills.
A demonstrated eye for good user experience (UX), with the ability to translate design concepts into functional, user-friendly interfaces.

Preferred Qualifications

Experience with TypeScript in React applications.
Familiarity with server-side rendering (SSR) and static site generation (SSG) using frameworks like Next.js.
Knowledge of CI/CD pipelines and DevOps practices.
Experience with responsive design and cross-browser compatibility.
Understanding of accessibility standards (WCAG) and best practices.
Experience working closely with UX/UI designers to implement pixel-perfect designs.
