  • Ensure seamless integration with front-end applications and external services through well-designed RESTful APIs.

  • Leverage cloud infrastructure (Azure Functions, Azure Storage) for hosting and scaling applications.

  • Implement security best practices for API authentication (OAuth, JWT) and data protection.

  • Work on GenAI-driven applications, utilizing frameworks such as LangChain, LlamaIndex, vector databases, and agentic frameworks.

  • Containerize applications using Docker for environment management.

  • Collaborate with cross-functional teams to transition POCs into full-scale production systems.

Job requirements

  • Expertise in Python for back-end development.

  • Experience with FastAPI (or similar frameworks) for building scalable RESTful APIs.

  • Experience in Typescript (React.js) for building frontends.

  • SQL DBs knowledge (PostgreSQL or equivalent).

  • Knowledge of message-queueing solutions (RabbitMQ, Kafka).

  • API Design & Integration: Strong proficiency in designing and managing RESTful APIs.

  • Observability and tools like OpenTelemetry

  • Azure Cloud Services: Hands-on experience with Azure Functions, Azure Storage, and cloud-based hosting.

  • Asynchronous Programming: Understanding of async patterns to improve performance.

  • Containerization: Familiarity with Docker for application deployment.

  • Security Best Practices: Knowledge of API authentication methods such as OAuth and JWT.

Preferred Experience

  • Experience converting POC applications to production-ready systems.

  • GenAI Knowledge: Experience working with Retrieval-Augmented Generation (RAG), vector databases, and AI frameworks.

  • Performance optimization using monitoring tools and profiling techniques.

  • Unit testing & automation (PyTest, Unittest).
