  • 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.

Qualifications:

  • Bachelor’s or master’s degree in Computer Science, Data Science, AI, or a related field.

  • 5–7 years of experience in AI/ML, including significant experience in Generative AI.
