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

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

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
