Join our Full Stack Gen-AI Engineering Team

We’re building the next generation of MarTech platforms — combining scalable full-stack engineering with AI-assisted workflows. If you’re a developer who thrives across the stack, from clean UI to efficient APIs, and you love leveraging tools like GitHub Copilot or Cursor, this is your playground.

What You'll Work On

•Develop high-performance React.js frontends for dynamic enterprise SaaS products

•Good understanding of Vite, Webpack and Module Federation for building scalable micro frontends.

•Build scalable Node.js/Express backends with clean RESTful APIs and secure authentication

•Implement server-side rendering (SSR) and static site generation (SSG) with Next.js (bonus)

•Work with PostgreSQL, SQL database and integrate them into your services

•Collaborate closely with UI/UX, product, and backend teams for full feature delivery

•Use AI copilots (e.g., Copilot, Cursor) to speed up coding, debugging, and refactoring

•Ensure reliability via unit, integration, and end-to-end testing frameworks

What Sets This Role Apart

•AI-Enhanced Full Stack Development: Code smarter and faster with generative AI support

•Complete Ownership: From React components to backend logic and deployments

•Versatile Tech Stack: Exposure to a modern JS ecosystem across both client and server

•Mission-Critical Impact: Help build the future of Gen-AI driven MarTech infrastructure

•Next.js Exposure: Explore full-stack capabilities with SSR/SSG and API routes (good to have)

•Familiarity with DevOps basics, CI/CD pipelines, and cloud deployment (Docker, Azure, etc.)

What You Bring

•5+ years of professional relevant experience in JavaScript/TypeScript development

•Strong in React.js: Hooks, component architecture, state management (Redux / Zustand / Context API)

•Micro frontend Architecture: Experience in implementing Shell and Micro repository architecture using Vite/Webpack

•Microservices Architecture: Experience with deployment of microservices using Docker/ containerized environment.

• Backend experience with Node.js, Express, REST APIs, JWT Auth

•Good understanding of database modelling and queries (SQL and ORM)

•Experience with GitHub Copilot / Cursor, or similar AI-driven development tools

•Familiarity with Next.js (API routes, SSR/SSG concepts, routing)

•Proficient in writing and maintaining unit, integration, and API tests (Jest, React Testing Library)
