Key Responsibilities:

• Develop responsive, scalable, and dynamic user interfaces using Angular 12+, RxJS, and modern web technologies.
• Collaborate with AI/ML engineers and backend developers to build front-end interfaces for AI applications such as data dashboards, NLP interfaces, and real-time prediction visualizations.
• Integrate UI components with AI APIs, RESTful services, and real-time data streams (WebSockets, SSE).
• Build intuitive workflows and UX for tasks involving model feedback loops, user-assisted learning, or AI-assisted decision making.
• Apply performance optimization techniques for handling large datasets, charts, and AI inference results in the browser.
• Implement robust UI state management and asynchronous data flows using RxJS.
• Write clean, reusable code in HTML, CSS/SCSS, JavaScript, and follow best practices in responsive design and accessibility.
• Participate in Agile/Scrum development practices, code reviews, and CI/CD pipelines.

• Strong analytical thinking, debugging skills, and attention to detail.
• Knowledge of web accessibility standards and SEO best practices.
• Experience with unit testing frameworks (e.g., Jasmine, Karma).

Nice to Have

• Familiarity with WebSockets, or streaming data APIs.
• Understanding of UX challenges in AI interfaces (e.g., model explainability, user input for ML training).
