Job description

• As a Full-Stack AI Engineer, you’ll transform business ideas into production-ready applications using cutting-edge AI design tools and modern full-stack frameworks. With a strong bias toward frontend development, you specialize in the critical early stages—from concept through pre-totype to prototype—where design systems meet AI-augmented development
• You will join a team that thrives on experimentation, moving at a rapid pace from initial concepts through prototypes to production-ready applications
• Rapidly transform concepts into interactive prototypes using v0.dev, bolt.new, Lovable, and similar AI design tools
• Build full-stack applications from prototype to production, with emphasis on frontend excellence and solid backend foundations
• Ensure all components align with existing design systems (design tokens, color palettes, typography, spacing) and brand guidelines
• Develop production-ready UI components using modern frameworks (React.js, Vue.js, Nuxt.js) with best practices for accessibility, performance, and responsive design
• Design and implement RESTful APIs and backend services using platforms like Supabase to support frontend functionality
• Work with databases (SQL and NoSQL) to manage application data efficiently
• Implement authentication, caching strategies, and optimize application performance across the stack
• Collaborate with UX Designers, AI Builders, and Innovation Leads throughout the development lifecycle
• Utilize GitHub Spec-kit and/or Open Spec to streamline development workflows and maintain specification standards
• Leverage Figma and design system tooling to maintain component libraries and streamline design‑dev handoff
• Document design decisions and technical implementation in Jira as part of the ticket‑driven workflow
