We are looking for a MERN Stack Developer with 2+ years of real-world experience who thinks beyond CRUD APIs and UI screens. This role is for someone who understands how full-stack systems are designed, cares about scalability, performance, security, and clean architecture, and takes ownership of features end-to-end.

We value ownership, speed, clean code, and smart problem-solving. If you enjoy building products from scratch, thinking in systems, and shipping meaningful features—not just “finishing tasks”—this role is for you.

🧠 Key Responsibilities

• Design, develop, and maintain full-stack applications using MongoDB, Express, React, and Node.js
• Build scalable and maintainable backend APIs with proper validation, error handling, and security
• Develop clean, reusable, and performant React components
• Design database schemas and optimize queries for performance and scalability
• Translate product and business requirements into solid technical solutions
• Design frontend and backend architecture that can scale as the product grows
• Handle authentication, authorization, roles, and permissions
• Work with async operations, background jobs, and API integrations
• Manage application state properly (React state, context, or state libraries)
• Handle edge cases: loading, failure states, retries, and fallbacks
• Write clean, readable, and well-structured JavaScript / TypeScript code
• Follow and continuously improve coding standards and best practices
• Debug production issues using logs, reasoning, and root-cause analysis
• Review PRs, give constructive feedback, and contribute to team learning
• Work with designers to deliver good UX, not just “working UI”
• Collaborate closely with QA, design, and product teams
• Think ahead—identify technical debt, performance bottlenecks, and improvement areas
• Use AI tools responsibly to speed up development, debugging, and learning (with understanding)

✅ Qualifications Must Have

• 2+ years of hands-on experience with the MERN stack
• Strong knowledge of JavaScript and TypeScript, including OOP concepts
• Solid experience with Node.js & Express
• Hands-on experience with MongoDB, schema design, indexing, and aggregation
• Experience building and consuming REST APIs
• Strong understanding of async/await, promises, event loop
• Knowledge of HTML, CSS, responsive design (Tailwind / Bootstrap preferred)
• Experience with React hooks, component lifecycle, and state management
• Use React performance optimizations such as: React.memo useCallback, useMemo
• Implement code splitting and lazy loading using dynamic imports
• Work on or understand micro-frontend architecture and module federation
• Experience handling authentication (JWT, sessions, OAuth)
• Familiarity with Git, code reviews, and basic CI/CD concepts
• Exposure to real production issues (performance, bugs, scaling, failures, debugging)

Good to Have (Big Plus)

• Knowledge of Next.js or server-side rendering concepts
• Experience with Redis, queues (kafka, rabbitmq), or background jobs
• Experience with Docker, cloud deployments, or Nginx
• Understanding of performance tuning and lazy loading
• Experience working in a startup or fast-paced environment

❌ Who Should Not Apply

Please do not apply if:

• You only focus on “closing tickets” without questioning why something is being built
• You lack strong JavaScript fundamentals (arrays, objects, async/await, promises, event loop)
• You mostly copy-paste code without understanding it
• You never think about edge cases, failures, retries, or resilience
• You depend heavily on others for architecture or technical direction
• You avoid responsibility and say things like:
• “Frontend issue”
• “Backend issue”
• “It was already like this”
• “QA didn’t catch it”
• You are not comfortable explaining your code, decisions, or design choices
• You expect exact step-by-step instructions for every task
• You are not interested in learning and improving as a full-stack engineer

👉 This role is not for task executors.

We want problem solvers, thinkers and owners.

We're looking for an experienced Full-Stack Engineer who can architect and build AI-powered agent systems from the ground up. You'll work across the entire stack—from designing scalable backend services and LLM orchestration pipelines to creating frontend interfaces for agent interactions through widgets, bots, plugins, and browser extensions.

You should be fluent in modern backend technologies, AI/LLM integration patterns, and frontend development, with strong systems design thinking and the ability to navigate the complexities of building reliable AI applications.

Note: This is an on-site, 6-day-a-week role. We are in a critical product development phase where sthe peed of iteration directly determines market success. At this early stage, speed of execution and clarity of thought are our strongest moats, and we are doubling down on both as we build through our 0→1 journey.

WHAT YOU BRING:

You take ownership of complex technical challenges end to end, from system architecture to deployment, and thrive in a lean team where every person is a builder. You maintain a strong bias for action, moving quickly to prototype and validate AI agent capabilities while building production-grade systems. You consistently deliver reliable, scalable solutions that leverage AI effectively — whether it's designing robust prompt chains, implementing RAG systems, building conversational interfaces, or creating seamless browser extensions.

You earn trust through technical depth, reliable execution, and the ability to bridge AI capabilities with practical business needs. Above all, you are obsessed with building intelligent systems that actually work. You think deeply about system reliability, performance, cost optimization, and you're motivated by creating AI experiences that deliver real value to our enterprise customers.

WHAT YOU WILL DO:

Your primary responsibility (95% of your time) will be designing and building AI agent systems across the full stack. Specifically, you will:

• Architect and implement scalable backend services for AI agent orchestration, including LLM integration, prompt management, context handling, and conversation state management.
• Design and build robust AI pipelines — implementing RAG systems, agent workflows, tool calling, and chain-of-thought reasoning patterns.
• Develop frontend interfaces for AI interactions including embeddable widgets, Chrome extensions, chat interfaces, and integration plugins for third-party platforms.
• Optimize LLM operations — managing token usage, implementing caching strategies, handling rate limits, and building evaluation frameworks for agent performance.
• Build observability and monitoring systems for AI agents, including prompt versioning, conversation analytics, and quality assurance pipelines.
• Collaborate on system design decisions around AI infrastructure, model selection, vector databases, and real-time agent capabilities.
• Stay current with AI/LLM developments and pragmatically adopt new techniques (function calling, multi-agent systems, advanced prompting strategies) where they add value.

BASIC QUALIFICATIONS:

• 4–6 years of full-stack development experience, with at least 1 year working with LLMs and AI systems.
• Strong backend engineering skills: proficiency in Node.js, Python, or similar; experience with API design, database systems, and distributed architectures.
• Hands-on AI/LLM experience: prompt engineering, working with OpenAI/Anthropic/Google APIs, implementing RAG, managing context windows, and optimizing for latency/cost.
• Frontend development capabilities: JavaScript/TypeScript, React or Vue, browser extension development, and building embeddable widgets.
• Systems design thinking: ability to architect scalable, fault-tolerant systems that handle the unique challenges of AI applications (non-determinism, latency, cost).
• Experience with AI operations: prompt versioning, A/B testing for prompts, monitoring agent behavior, and implementing guardrails.
• Understanding of vector databases, embedding models, and semantic search implementations.
• Comfortable working in fast-moving, startup-style environments with high ownership.

PREFERRED QUALIFICATIONS:

• Experience with advanced LLM techniques: fine-tuning, function calling, agent frameworks (LangChain, LlamaIndex, AutoGPT patterns).
• Familiarity with ML ops tools and practices for production AI systems.
• Prior work on conversational AI, chatbots, or virtual assistants at scale.
• Experience with real-time systems, WebSockets, and streaming responses.
• Knowledge of browser automation, web scraping, or RPA technologies.
