Integrate AI models with enterprise systems, APIs, and data stores using Python, Java, or Node.js.

Collaborate with architects to define scalable, secure, and cost-efficient AI service architectures.

Implement AI/ML pipelines for training, validation, and deployment using tools like MLflow, Vertex AI, or Azure ML.

Monitor model performance, detect drift, and drive continuous improvement.

Optimize inference performance and cost through model compression, quantization, and API optimization.

Ensure compliance with AI ethics, security, and governance standards.

Prepare and curate training datasets (structured/unstructured text, images, code).

Apply data preprocessing, tokenization, and embedding generation techniques.

Work with vector databases (e.g., Pinecone, Weaviate, FAISS, Chroma) for semantic search and retrieval.

Partner with business stakeholders to identify and shape impactful AI use cases.

Contribute to the development of a strategic AI adoption roadmap and reusable AI Workbench/platform components.
