Technical Leadership and Architectural Guidance :

- Drive the adoption of modern React.js patterns (e.g., functional components, hooks, context API, state management libraries like Redux, Zustand, or MobX) and efficient component lifecycle management.

- Conduct in-depth code reviews, ensuring adherence to coding standards, performance optimization, security guidelines, and unit testing coverage using frameworks like Jest, Enzyme, or React Testing Library.

Team Management and Mentorship :

- Actively mentor junior and mid-level developers, providing technical coaching on complex front-end challenges, debugging techniques, and career growth.

- Manage team capacity, sprint planning, task assignments, and daily stand-ups within an Agile/Scrum framework, ensuring project milestones are met on time and within scope.

Hands-on Development and Quality Assurance:

- Develop and maintain scalable React.js applications, ensuring maximum performance across a wide array of web-capable devices and browsers.

- Implement pixel-perfect designs with semantic HTML5 and robust Cascading Style Sheets (CSS), utilizing modern techniques such as CSS-in-JS (e.g., Styled Components), Sass/Less, or utility-first frameworks like Tailwind CSS for responsive web design.

Collaboration and Communication :

- Work closely with Backend Developers (e.g., Node.js, Java, Python) to define and integrate application programming interfaces (APIs), primarily focusing on RESTful services or GraphQL endpoints.

- Articulate complex technical concepts, trade-offs, and solutions clearly to non-technical stakeholders and executive leadership.

Software Development Best Practices :

- Ensure the implementation of accessibility standards (WCAG) and internationalization/localization best practices.

- Maintain continuous integration/continuous deployment (CI/CD) pipelines related to front-end builds and deployments (e.g., using Jenkins, GitLab CI, or GitHub Actions).

Required Skills and Qualifications :

- Minimum of 7+ years of experience in Software Development, with at least 4 years focused intensely on React.js and its core principles.

- Expert-level proficiency in JavaScript (ES6+) and TypeScript, including asynchronous programming and modular design.

- Deep practical experience with a major state management library such as Redux Toolkit, or similar centralized stores.

- Solid understanding of the Document Object Model (DOM), browser rendering behaviors, and performance optimization techniques (e.g., code splitting, lazy loading, memoization).

- Proven experience in a Team Leadership, Tech Lead, or Senior Developer role, including responsibility for code quality, architectural decisions, and team mentorship.

- Strong knowledge of responsive design implementation and cross-browser compatibility issues.

- Demonstrated excellence in problem-solving and debugging complex client-side application issues.

- Excellent verbal and written communication skills for internal and external stakeholder interaction.

Preferred Skills :

- Familiarity with full-stack development concepts or experience with Node.js as a backend or BFF (Backend for Frontend) layer.

- Experience with server-side rendering (SSR) frameworks like Next.js or static site generators (SSG).

- Experience implementing robust end-to-end testing with frameworks such as Cypress or Playwright.

- Knowledge of cloud platforms and services relevant to front-end hosting and deployment (AWS Amplify, Netlify, Vercel, or Azure App Services).

- Contributions to open-source projects or an active portfolio demonstrating technical capabilities.

- Prior experience with accessibility standards (A11y/WCAG compliance)
