• Smart UX interactions (predictive inputs, adaptive layouts)
• Automated test generation or visual regression checks using AI
• In-app recommendations or personalization
• Champion frontend quality and reliability through AI-assisted testing, such as visual diffs, behavioral monitoring, and intelligent code review pipelines.
• Mentor junior developers and help shape best practices in coding, testing, and performance optimization.
• Identify and introduce tools or frameworks that support AI-enabled development, including prompt engineering strategies, API wrappers, or integration patterns for LLM-based services.

WHAT WE ARE LOOKING FOR..

• 5+ years of professional experience in frontend development with frameworks like Vue.js
• Deep understanding of HTML/CSS/JavaScript/TypeScript and browser performance best practices
• Experience building production systems that consume REST or GraphQL APIs
• Solid understanding of software architecture principles and design patterns
• Exposure to AI/ML technologies, with practical experience integrating them into user-facing applications

• Experience with AI-powered QA automation or code generation tools is preferred
• Comfortable with Python or other ML-adjacent scripting languages
• Knowledge of MLOps or model lifecycle considerations in the frontend context
• Prior experience in product domains involving personalization, content generation, or automation is preferred
• Experience with Microfrontend architecture

Nice to Have:
