Job Title: Senior MERN Stack Developer

Company: The Growth Square

Experience Required: 2+ years

Openings: 5

Employment Type: Full-time

Location: On-site, Indiranagar, Bangalore

Salary Range: ₹4 lakh – ₹12 lakh per annum

What you'll do

  • Build and maintain full-stack web applications on the MERN stack: React frontends, Node.js and Express.js APIs, and MongoDB databases.
  • Use AI coding tools (such as Claude Code, Cursor, GitHub Copilot or similar) daily to plan, write, review, test and refactor code.
  • Integrate LLM features into our products, such as chat, content generation, summarisation and automated workflows, using APIs from providers like Anthropic and OpenAI.
  • Turn business requirements into clean, well-tested and maintainable code.
  • Review pull requests from teammates and AI tools critically for correctness, security and performance before code is merged.
  • Work closely with design, marketing and growth teams to launch and iterate on features quickly.
  • Write clear documentation and share what you learn about new AI tools with the team.

What you must have

  • At least 2 years of professional full-stack experience building with the MERN stack.
  • MongoDB: schema design, Mongoose, aggregation pipelines and indexing.
  • Express.js and Node.js: building RESTful APIs, middleware, and authentication (JWT, OAuth).
  • React: hooks, component-driven UI, and state management (Redux, Zustand or Context API).
  • Strong JavaScript (ES6+) skills; working knowledge of TypeScript.
  • Regular, practical use of the latest AI and LLM coding tools, such as Claude Code, Cursor, GitHub Copilot or Windsurf, as part of your daily workflow.
  • Good understanding of how LLMs work in practice: prompting, context, API usage and their limitations.
  • Strong Git skills and a pull request (PR)-based workflow: branching, rebasing, resolving merge conflicts and writing clear PRs. Hands-on experience reviewing PRs and giving clear, constructive feedback is required.
  • Clear communication and the ability to work independently and take ownership.

Nice to have

  • Experience deploying and running applications on platforms like Vercel, Netlify, AWS, Google Cloud or Azure.
  • Familiarity with Docker, CI/CD pipelines (such as GitHub Actions) and environment management.
  • Experience with monitoring, logging and debugging apps in production.
  • Exposure to AI app building blocks: vector databases, embeddings, RAG (retrieval-augmented generation), AI agents or MCP (Model Context Protocol).
  • Experience with Next.js, Tailwind CSS, Socket.io for real-time features, or SQL databases such as PostgreSQL.
  • Interest in marketing, growth or analytics products.
  • A portfolio, GitHub profile or side projects that show what you've built with AI.
