Job Summary

We are seeking a highly experienced Senior Python & Generative AI Engineer with deep expertise in Python backend engineering, Large Language Models (LLMs), and modern Generative AI frameworks. The ideal candidate will lead end-to-end development of AI solutions, build scalable microservices, architect RAG pipelines, and fine-tune state-of-the-art LLMs for enterprise applications. This role requires strong hands-on coding skills, architectural thinking, and the ability to work with cross-functional teams.

Key Responsibilities

  • Design and develop enterprise-grade Generative AI solutions using LLMs (GPT, Claude, Gemini, LLaMA, Mistral).

  • Build and deploy RAG (Retrieval Augmented Generation) pipelines using LangChain, LlamaIndex, and vector databases.

  • Architect and implement Python-based backend services using FastAPI/Django/Flask.

  • Lead LLM fine-tuning, LoRA/QLoRA customization, and evaluation of model performance.

  • Develop vector embeddings pipelines using HuggingFace, sentence-transformers, FAISS, Pinecone, ChromaDB.

  • Build scalable microservices and APIs supporting high-volume traffic.

  • Collaborate with data engineering teams to develop ETL, data ingestion pipelines, and model-ready datasets.

  • Optimize AI models, reduce latency, and improve system performance.

  • Integrate AI models with cloud platforms such as AWS/Azure/Google Cloud Platform using SageMaker, Vertex AI, or Azure OpenAI.

  • Implement MLOps workflows including CI/CD, model monitoring, drift detection, and versioning.

  • Work with product teams to understand requirements and convert them into scalable AI solutions.

  • Conduct code reviews, mentor junior developers, and guide architecture decisions.

Required Skills & Experience

  • 10 15 years of hands-on experience in Python development.

  • Strong experience in PyTorch or TensorFlow for model training and fine-tuning.

  • Deep knowledge of vector databases (FAISS, Pinecone, Milvus, ChromaDB).

  • Solid experience with FastAPI, Django, Flask, REST API development.

  • Strong understanding of cloud platforms (AWS/Azure/Google Cloud Platform) and container orchestration (Docker, Kubernetes).

  • Experience with MLOps tools such as MLflow, Airflow, Jenkins, GitHub Actions.

  • Strong SQL and NoSQL database experience.

  • Ability to design and implement scalable data pipelines.

  • Excellent debugging, code optimization, and system design skills.

Preferred Qualifications
