- Follow Git-based CI/CD practices using GitHub/GitLab, Jenkins, or Docker.

- Build LLM-orchestrated applications using LangGraph and LangChain.

- Wire up OpenAI, Anthropic, HuggingFace, or custom LLMs into production systems.

- Build and tune RAG pipelines on vector databases like Pinecone or PGVector.

- Work with PostgreSQL/MySQL and write efficient queries for large datasets.

- Bring cloud experience (AWS/GCP/Azure) to the table where relevant.

What You'll Need :

- 3 - 4+ years building applications with Python/Django.

- Strong hands-on experience building and consuming REST APIs.
