Role Summary

We are seeking a skilled Front-End Web Developer to design, build, and optimize user interfaces for our web applications using the React framework. This role is ideal for a developer who is passionate about delivering seamless, responsive, and high-performance web experiences. While the primary focus will be on front-end development, familiarity with back-end technologies is a plus and will be beneficial for collaborating with full-stack developers and contributing to the integration of front-end and back-end systems.
 

Core Requirements (The Must-Haves)

  • React.js: Strong experience with React, including state management (Redux or React Context), hooks, component design, and lifecycle methods.
  • HTML/CSS: Solid understanding of HTML5, CSS3, and pre-processors like SASS/LESS, with an emphasis on responsive design and mobile-first development.
  • JavaScript: Proficiency in modern JavaScript (ES6+) and TypeScript, including asynchronous programming, Promises, and fetching data from APIs.
  • Version Control: Experience using Git for source code management (GitHub, GitLab, or similar).
  • Testing Frameworks: Experience with front-end testing tools like Jest, React Testing Library, or Cypress.
  • Design Tools: Familiarity with design systems and tools like Figma, Sketch, or Adobe XD.

Preferred Qualifications (The Nice-to-Haves)

  • Node.js/Express: Familiarity with back-end development using Node.js and Express to assist in front-end and back-end integration.
  • Database Knowledge: Understanding of database management (e.g., MySQL, PostgreSQL, MongoDB) for better collaboration with back-end teams and understanding data flow.
  • Map Visualization tools: Experienced using Mapbox, Kepler.gl or DeckGl.
  • API Integration: Experience consuming and integrating RESTful APIs or working with GraphQL.
  • Authentication: Basic knowledge of authentication methods (JWT, OAuth) and user session management.
  • DevOps & Deployment: Familiarity with CI/CD pipelines, cloud services (AWS, Google Cloud Platform, or Azure), or containerization (Docker) is a plus.

 

Key Responsibilities

  • Front-End Development: Build and maintain responsive, accessible, and high-performance user interfaces using React.js and related libraries (e.g., Redux, React Router).
  • Performance Optimization: Ensure that web applications are optimized for maximum speed and scalability across a variety of devices and browsers.
  • Component Design: Design reusable and modular components, ensuring code maintainability and consistency across the application.
  • Cross-Browser Compatibility: Ensure cross-browser compatibility and resolve any issues related to HTML, CSS, and JavaScript performance across different platforms.
  • Testing & Debugging: Write unit and integration tests for React components, and perform debugging and troubleshooting to ensure application stability.
  • Collaboration: Work closely with back-end developers, product managers, and other team members to deliver integrated web solutions that meet business requirements.

 

Personal Attributes

  • Problem Solver: Strong analytical and troubleshooting skills, with the ability to 
    solve front-end challenges efficiently
  • Attention to Detail: A keen eye for design consistency, user experience, and 
    performance optimizations.
  • Team Player: Excellent collaboration skills and the ability to work cross-functionally 
    with designers, product managers, and back-end developers.
  • Curious & Adaptable: Passion for learning new technologies and techniques, and 
    adapting to evolving industry trends and tools.
  • Time Management: Ability to manage multiple tasks and deliver high-quality work 
    within deadlines.
