Job Description :

Key Responsibilities

· Develop responsive frontend applications using ReactJS (Hooks, state management) to support backend-driven features

· Integrate AI and LLM-powered capabilities into backend services, including agentic workflows and tool-calling patterns

· Apply MCP (Model Context Protocol) concepts to connect AI agents with backend services, APIs, and data sources

· Collaborate with cross-functional teams on API contracts, data flows, and end-to-end feature delivery

Design and develop scalable, production-grade backend services using Python frameworks (FastAPI / Flask / Django)

· Architect, build, and integrate RESTful APIs and backend microservices with strong attention to performance, reliability, and security

· Design and optimize relational database structures using PostgreSQL / MySQL / SQL Server — including schema design, indexing strategies, query optimization, and data modeling

· Implement robust authentication and authorization frameworks beyond basic JWT — including OAuth 2.0 / OpenID Connect, SSO integrations, session management, token lifecycle (refresh/rotation/revocation), and role-based / attribute-based access control (RBAC/ABAC)

Must-Have Skills

AI / Agentic AI / MCP: Solid understanding of LLM fundamentals, agentic AI architectures (planning, tool use, multi-step workflows), and the Model Context Protocol (MCP) for agent–system integration; familiarity with frameworks such as LangChain / LangGraph is a strong plus

· Python Backend (Primary): Strong, hands-on experience building backend services with FastAPI / Flask / Django — async patterns, dependency injection, middleware, API versioning, testing, and production deployment

· Databases: Deep practical experience with PostgreSQL / MySQL / SQL Server — complex queries, joins, indexing, transactions, ORM usage (SQLAlchemy / Django ORM), and performance tuning

· Authentication & Security: Demonstrated depth in auth frameworks beyond JWT basics — OAuth 2.0, OIDC, SSO, RBAC, secure session handling, and API security best practices

· RESTful APIs: Proven experience designing, building, and integrating REST APIs and backend services at scale

· ReactJS (Secondary): Hands-on expertise with ReactJS — Hooks, component lifecycle, and state management (Redux / Context API)
