Responsibilities :

Build and optimize interactive, responsive web applications that deliver a high-quality user experience. Ensure seamless functionality across all modern browsers and devices.

Write clean, efficient, and maintainable JavaScript code using Vue.js for dynamic interfaces and vanilla JavaScript for lightweight, performance-driven features.

Create and maintain extensive, reusable component libraries, both with and without frameworks, to streamline development processes and ensure consistency across projects.

Ensure that your code is optimized for size and speed, balancing performance with ease of maintenance.

Write efficient, flexible CSS to style user interfaces, ensuring they adapt seamlessly across different screen sizes and devices. Utilize modern CSS frameworks (e.g., Flexbox, CSS Grid) and best practices for responsive design.

Consume RESTful APIs and handle asynchronous data retrieval using HTTPS requests. Ensure smooth data flow and error handling for dynamic content updates.

Continuously evaluate and enhance the user experience by identifying areas for improvement, applying design patterns, and integrating feedback.

Implement SEO best practices to improve search engine visibility where applicable, particularly in the context of front-end rendering.

Write unit tests and perform extensive testing to identify bugs, optimize performance, and ensure code quality. Utilize modern testing frameworks to automate regression testing.

Collaborate effectively with back-end developers, designers, and other team members to deliver integrated solutions that meet business requirements and technical specifications.

Perform other related tasks as assigned, demonstrating flexibility and adaptability in a fast-paced environment.

Requirements :

3+ years of experience in front-end development with a strong focus on Vue.js and vanilla JavaScript. Proven ability to manipulate the DOM and develop complex UI components.

In-depth understanding of JavaScript, including theoretical concepts such as closures, event delegation, asynchronous programming (Promises, async / await), and modern ES6+ features.

Solid experience with front-end HTML / CSS, including responsive design and pre-processors (e.g., SASS / SCSS).

Experience with RESTful API integration, handling asynchronous calls, and managing data flow between the front-end and back-end systems.

Strong problem-solving skills and a passion for clean, optimized code that balances functionality, maintainability, and performance.

A keen eye for detail and a strong commitment to delivering high-quality, user-centric interfaces.

Ability to work independently and as part of a collaborative team, taking ownership of tasks while also contributing to team efforts.

Experience with version control (Git) and following best practices for code management, branching, and deployment.

Understanding of SEO principles and how they apply to front-end development.

Preferred Qualifications :

Experience with analytical platforms and working on data-driven projects, particularly those that involve presenting large datasets in an intuitive and accessible manner.

Familiarity with data visualization tools and libraries (e.g., Chart.js, D3.js) to create dynamic graphs and charts.

Hands-on experience building real-time or auto-updating interfaces, such as dashboards or live data feeds.

Experience with developing and optimizing complex grid systems (e.g., data tables, filtering, pagination).

Familiarity with Web Performance Optimization (WPO) techniques, such as lazy loading, code splitting, and caching strategies to enhance application speed and efficiency.

Desired Qualifications :

Strong understanding of networking concepts, HTTP protocols, caching strategies, and performance best practices.

Experience with additional JavaScript frameworks (e.g., React, Angular) and familiarity with modern front-end development practices, such as component-based architecture and state management (Vuex, Redux).

Familiarity with CI / CD pipelines and tools for automating build and deployment processes.

Knowledge of design systems and experience collaborating with UX / UI designers to translate designs into functional web interfaces.

Experience with cloud platforms (e.g., AWS, Google Cloud) and deploying web applications in a cloud environment is a plus.
