• Apply advanced techniques including ensemble methods, gradient boosting, deep learning, NLP, time-series forecasting, and recommendation systems.
• Ensure model robustness through rigorous validation, monitoring, and performance tracking.

Generative AI & LLM Applications

• Design and implement Generative AI solutions leveraging large language models (LLMs) for use cases such as knowledge retrieval, content intelligence, metadata enrichment, summarization, and workflow automation.
• Develop and optimize prompt engineering strategies, evaluation frameworks, and guardrails to ensure high-quality, reliable outputs.
• Architect Retrieval-Augmented Generation (RAG) pipelines integrating structured and unstructured enterprise data sources.
• Fine-tune or adapt foundation models where appropriate using parameter-efficient techniques (e.g., LoRA, adapters) aligned with business needs.
• Implement evaluation pipelines to measure hallucination rates, bias, latency, cost efficiency, and model quality in production environments.
• Collaborate with Responsible AI and Governance teams to ensure compliance with enterprise AI policies, data privacy standards, and ethical AI practices.

Product Ionization & AI Engineering

• Collaborate with Data Engineering and DevOps teams to productionize ML and GenAI solutions in scalable cloud environments.
• Design CI/CD pipelines for model lifecycle management, including experimentation tracking, versioning, and automated retraining.
• Implement monitoring frameworks for model drift, prompt drift, performance degradation, and data integrity.

Automation & AI Framework Development

• Develop reusable ML and GenAI frameworks, accelerators, and internal utilities that improve productivity across teams.
• Advance automation initiatives to reduce manual workflows and enhance analytical velocity.
• Stay current with cutting-edge advancements in foundation models, multimodal AI, and agentic architectures to continuously elevate enterprise AI capabilities.

• Bachelor's degree, MS, or greater in Computer/Data Science, Engineering, Mathematics, Statistics, or related quantitative discipline.
• 8+ years relevant experience in data science, 2+experience in GenAI
• Demonstrated track record of delivering production-grade AI/ ML solutions with measurable business impact.

Generative AI & Large Language Model (LLM) Expertise

• Hands-on experience designing and deploying Generative AI solutions using large language models (e.g., GPT-class models, open-source foundation models, or enterprise LLM platforms).

• Strong proficiency in prompt engineering, structured output design, few-shot learning strategies, and systematic prompt optimization

• Experience building Retrieval-Augmented Generation (RAG) pipelines integrating vector databases and enterprise data sources.

• Familiarity with embedding models, semantic search, and vector stores (e.g., Pinecone, Weaviate, OpenSearch, FAISS, or equivalent).

• Experience fine-tuning or adapting foundation models using parameter-efficient approaches (e.g., LoRA, adapters, instruction tuning).

• Understanding of LLM evaluation methodologies, including hallucination detection, bias assessment, response quality scoring, and cost-performance trade-offs.

• Exposure to multimodal AI (text, image, audio, video) and agent-based workflows is a plus.

• Experience working with enterprise AI platforms (e.g., AWS Bedrock, Azure OpenAI, Databricks Model Serving, Snowflake Cortex, or equivalent).

• Understanding of Responsible AI principles, data privacy considerations, and model governance requirements in regulated environments.
