Responsibilities:
- Lead the redesign and development of responsive, intuitive user interfaces using React, HTML5, CSS, and Material UI (MUI).
- Rewrite existing ASP.NET and jQuery-based UI components into a modern React-based application, dedicating ~70-80% of time to new development and ~20-30% to maintaining legacy systems.
- Independently design and implement UI projects, collaborating across teams (modernization and experience teams) on project-based assignments.
- Contribute to and maintain a shared UI library, ensuring consistent and scalable design across the organization.
- Collaborate with product and design teams to translate requirements, wireframes, and mockups into functional components aligned with product goals.
- Optimize UI components for performance, accessibility, and cross-browser compatibility.
- Implement AJAX calls and ensure seamless integration with RESTful APIs and backend services.
- Participate in agile development processes, including sprint planning, daily stand-ups, and retrospectives.
- Perform code reviews to uphold coding standards and best practices.
- Test components across multiple web browsers to ensure consistent user experiences.
Qualifications:
Required:
- 3-5 years of professional UI/UX development experience, with a strong emphasis on React, HTML5, CSS, and JavaScript (ES6+).
- Proficiency in Material UI (MUI), Storybook, and responsive design principles.
- Experience with API communication, AJAX calls, and integrating modern and legacy JavaScript technologies.
- Strong troubleshooting and performance optimization skills.
- Ability to work independently, manage time effectively, and handle project-based assignments across multiple teams.
- Clear and professional communication skills, with the ability to collaborate effectively in a team environment.
Preferred:
- Familiarity with legacy systems, including jQuery and ASP.NET.
- Experience with test automation frameworks (Playwright, Jest, Enzyme).
- Knowledge of server-side rendering frameworks (Next.js, Gatsby).
