About Position:

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).

• Role: Full Stack Developer (Python-Heavy / Backend-Focused)
• Location: Miami, FL
• Experience: 12+
• Job Type: Full-Time Employment
• Mandatory Mention 3 skills: Python, React and GenAI

What You'll Do:

• 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

Expertise You'll Bring:

• 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)
• 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

Benefits:

• Competitive salary and benefits package
• Culture focused on talent development with quarterly growth opportunities and company-sponsored higher education and certifications
• Opportunity to work with cutting-edge technologies
• Employee engagement initiatives such as project parties, flexible work hours, and Long Service awards
• Insurance coverage: group term life, personal accident, and Mediclaim hospitalization for self, spouse, two children, and parents

Values-Driven, People-Centric & Inclusive Work Environment:

Persistent is dedicated to fostering diversity and inclusion in the workplace. We invite applications from all qualified individuals, including those with disabilities, and regardless of gender or gender preference. We welcome diverse candidates from all backgrounds.

• We support hybrid work and flexible hours to fit diverse lifestyles.
• Our office is accessibility-friendly, with ergonomic setups and assistive technologies to support employees with physical disabilities.
• If you are a person with disabilities and have specific requirements, please inform us during the application process or at any time during your employment
