Key Responsibilities:

• Collaborate with AI architects, leads, and stakeholders to design and implement generative AI solutions that address business challenges.
• Develop, fine-tune, and optimize large language models (LLMs), leveraging both parameter-efficient techniques and full fine-tuning where applicable.
• Implement and experiment with advanced generative AI methods, including prompt engineering and Retrieval-Augmented Generation (RAG).
• Support the integration of AI models into production environments, ensuring robust deployment, scalability, and maintainability.
• Contribute to the development and optimization of real-time and streaming AI solutions.
• Stay current with the latest advances in generative AI and actively share knowledge with the team.
• Ensure adherence to ethical AI guidelines, data privacy, and compliance standards.
• Mentor junior team members, provide code reviews, and foster a culture of technical excellence.

Required Technical Skills:

• Strong hands-on experience with LLMs and fine-tuning methods such as LoRA, QLoRA, Adapter/Prefix Tuning, and instruction tuning.
• Practical knowledge of model optimization (compression, quantization) and familiarity with tools such as DeepSpeed, vLLM, GPTQ, or similar.
• Proficient in prompt engineering and familiarity with prompt design tools/frameworks.
• Experience building RAG systems, including hybrid search and multi-vector retrieval.
• Proficient with machine learning frameworks (PyTorch, TensorFlow, Keras) and distributed training.
• Strong skills in NLP (NER, Dependency Parsing, Text Classification, Topic Modeling), transfer learning, and advanced learning paradigms.
• Experience with containerization (Docker), orchestration (Kubernetes), and CI/CD pipelines for ML models.
• Familiarity with generative AI tools like LangChain, LlamaIndex, Langgraph, Crew.ai, autogen, Hugging Face, and major GenAI APIs (OpenAI, Gemini, Claude, etc.).
• Solid understanding of AI compliance, guardrails, and responsible AI practices.
• Strong skills in Python and experience with data preprocessing, feature engineering, and API development.

Required Soft Skills:

• Strong collaboration skills to work effectively in cross-functional teams.
• Analytical and proactive approach to problem-solving.
• Clear communication skills for both technical and non-technical audiences.
• Eagerness to learn, innovate, and mentor less experienced developers.
