Full Stack Developer Python Heavy Backend Focused

Role : Full Stack Developer (Python-Heavy / Backend-Focused)

Location : Miami, FL (Hybrid 3 days)

Profile Mix: ~80 90% Python/Backend, ~10 20% ReactJS Frontend

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).

Must-Have

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 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
