ZettaMine - Senior Generative AI Engineer - Python Programming

Job Description :

We are looking for a Senior Generative AI Engineer who is passionate about cutting-edge AI innovation and has significant hands-on experience in building and deploying Generative AI models. In this role, you will be responsible for designing, fine-tuning, and optimizing large language models (LLMs), implementing innovative GenAI solutions, and contributing to the architecture of AI-driven platforms that deliver real business value.

You will collaborate with cross-functional teams including data scientists, machine learning engineers, product managers, and cloud infrastructure teams to build scalable, reliable, and secure AI systems. This is a high-impact position where you will directly influence the AI roadmap and innovation strategy.

Key Responsibilities :

- Design, develop, and fine-tune state-of-the-art Generative AI and LLM models tailored for various business use cases.

- Build, integrate, and optimize solutions using transformer-based architectures (e.g., GPT, BERT, T5, LLaMA, Mistral).

- Apply techniques such as fine-tuning, prompt engineering, RLHF (Reinforcement Learning from Human Feedback), and knowledge distillation to improve model performance.

- Work with vector databases (e.g., FAISS, Pinecone, Weaviate) for implementing retrieval-augmented generation (RAG) pipelines.

- Develop and deploy embedding models and integrate them into LLM pipelines.

- Collaborate with engineering and product teams to deploy scalable AI systems using MLOps practices and CI/CD pipelines.

- Leverage LangChain, Hugging Face Transformers, OpenAI APIs, and similar frameworks/tools to accelerate development.

- Optimize model performance across different environments (cloud/on-premise).

- Develop end-to-end pipelines, from data preprocessing to real-time inference and monitoring.

- Ensure high standards of software quality, including testing, version control, code reviews, and documentation.

- Stay up to date with the latest research in Generative AI and translate breakthroughs into production-ready solutions.

Required Skills & Qualifications :

- Experience : 7+ years in AI/ML, data science, or software engineering; at least 3 - 4 years in Generative AI/LLMs.

- Advanced Python programming skills, including familiarity with object-oriented design and software engineering best practices.

- Deep expertise in PyTorch, TensorFlow, Transformers (Hugging Face), LangChain, and OpenAI or Anthropic APIs.

- Experience in LLM fine-tuning, parameter-efficient tuning methods (LoRA, PEFT), RLHF, and model evaluation.

- Experience with embeddings, vector stores (FAISS, Pinecone), semantic search, and RAG systems.

- Hands-on experience with AWS, GCP, or Azure; knowledge of MLOps tools (SageMaker, Vertex AI, MLflow, Kubeflow) for training, deploying, and monitoring models.

- Familiarity with structured/unstructured data handling and integrating AI systems with SQL/NoSQL databases.

- Strong analytical thinking, problem-solving ability, and a keen interest in research and innovation.
