• Full Stack Ownership: Build and maintain scalable web and mobile apps with React, React Native, Node.js, and GraphQL.
• Create end-to-end solutions from designing and optimizing backend services, APIs, and microservices to contributing to the Craft of intuitive, pixel-perfect User Interfaces that perform beautifully on Web, iOS, and Android.
• AI-Powered Features (Optional, but exciting!): Collaborate on the design and implementation of AI-driven features using APIs like OpenAI or Gemini.
• Infrastructure Impact: Work with AWS to keep our systems secure, scalable, and lightning-fast.
• Code Quality & Performance: Improve- and keep our codebase clean, efficient, and easy to build on.
• Mentorship & Innovation: Share your expertise, guide junior engineers, and bring your freshest ideas to the table.

What We’re Looking For 

Are you the frontend innovator we’ve been searching for?

Must-Have Experience:

• 5+ years in JavaScript development (React, TypeScript, Node.js, and React Native expertise)
• Proven experience in full stack development - building both frontend and backend systems
• Some exposure to AI-powered tools, APIs, or projects (commercial or personal)
• GraphQL proficiency
• Solid understanding of microservices architecture
• Product Mindset: you think about the why behind the code

Bonus Points (bring these and we’ll be extra hyped!)

• Experience building AI models or advanced AI features
• Strong AWS and infrastructure skills
• Experience with basic DevOps (CI/CD, monitoring, or deployment pipelines).
• A sharp design intuition with an eye for UX/UI polish
