The Stack: Strong Python skills and experience with PostgreSQL/pgvector. Exposure to Neo4j or other graph databases is a plus. Domain curiosity: You don't need to be a CFA, but you should be interested in how financial markets work and how data is used to drive an investment decision. Background: 1-2 years of experience or a graduate with a portfolio of data-heavy projects (Web scraping, ETL pipelines, or RAG applications).
