Deploy and maintain Python-based GenAI services in production, leveraging Bitbucket, Git, and CI/CD tools for reliable releases. Architect secure API communication and access management, using JWT, OAuth, and RBAC, to safeguard sensitive client data. Apply NLP, LLM, and retrieval techniques, including vector stores and embeddings, to build context-aware, intelligent solutions for clients. Qualifications Your Skills & Experience: Strong Python fundamentals (OOP, data structures, error handling) with hands-on experience using Pandas, NumPy, PySpark, or Dask. Hands-on experience with LangChain, LangGraph, and Semantic Kernel, building agent orchestration, memory, and tool-use workflows. Proficiency in Python API frameworks (Flask/FastAPI), with experience using IDEs such as VSCode and PyCharm. Working knowledge of SQL/NoSQL databases, time-series data, and data modeling and schema design. Basic integration experience with TensorFlow or PyTorch, plus exposure to vector databases (e.g., FAISS, Chroma) and embedding-based retrieval. Proficiency with AWS Cloud Services and production deployment practices, including Bitbucket, Git, and CI/CD tools. Strong understanding of security & access management – JWT, OAuth, RBAC – and secure API communication. Additional information Set Yourself Apart With: Prior work on GenAI, CoPilot, or RAG-based systems. Familiarity with marketing data models and real-time customer journeys. Exposure to NLP, LLMs, and retrieval frameworks beyond the core requirements above.
