## About the Role

We are seeking a highly skilled Full Stack Developer with deep, hands-on Python backend engineering experience as the core of the role, complemented by working proficiency in ReactJS for frontend development. This is a backend-first full-stack position - candidates must demonstrate strong depth in Python services, database design, and authentication/authorization frameworks, along with a solid understanding of AI, Agentic AI systems, and the Model Context Protocol (MCP)., · 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)

· 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

Must-Have Skills:

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

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

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

Candidate Profile Expectations

Backend-dominant full-stack engineer: roughly 80-90% Python/backend and 10-20% React in day-to-day work, must have AI experience.

Must be able to demonstrate, in technical conversation, real depth in Python, database design, and authentication frameworks - not just frontend fluency

Frontend-heavy profiles (e.g., 80/20 frontend/backend) will not be a fit for this role

## Description

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