• Solid understanding of machine learning frameworks (e.g. TensorFlow, PyTorch) and how they interact with data platforms

• Experience with data classification, including identification and handling of PII and sensitive data

• Knowledge of RAG architectures, agent-based systems, and LLMpowered solutions

• Experience working with vector databases, embeddings, indexing, and reranking techniques to improve LLM output quality

• Ability to leverage cloud AI services (e.g. SageMaker, Comprehend, Entity Resolution or equivalents)

• Experience deploying and operating data and ML workloads at scale in cloud environments

• Strong understanding of core cloud services, including IAM, VPC, compute, object storage, relational databases, monitoring, and logging

• Excellent analytical and problem-solving skills, with a proactive and innovative mindset
