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) * 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 ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Get started with securing your cloud-native Java microservices applications](https://www.wearedevelopers.com/videos/123-get-started-with-securing-your-cloud-native-java-microservices-applications) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Postgres in the Age of AI (and Devin)](https://www.wearedevelopers.com/videos/1042-postgres-in-the-age-of-ai-and-devin) ## Related Articles - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [20 Essential Tools For Backend Development](https://www.wearedevelopers.com/magazine/218-20-essential-tools-for-backend-development) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The 13 Best Python Libraries for Developers in 2025](https://www.wearedevelopers.com/magazine/371-the-13-best-python-libraries-for-developers-in-2025)
