• Experience implementing AI solutions including LLM integration, prompt engineering, Retrieval-Augmented Generation (RAG) and vector databases.
• Experience working with SQL and NoSQL databases, with knowledge of platforms such as SQL Server, Snowflake, OneLake or similar data platforms.

• Experience working within Financial Services or another regulated environment would be advantageous.
• Excellent communication skills with the confidence to work directly with business stakeholders and explain complex technical concepts.
