Job description

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).

Key Responsibilities

• 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)
• 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
