• Build, enhance, and maintain core analytic SQL databases used by the trading team.

• Contribute to internal analytics platforms, APIs, and shared Python packages.

• Collaborate directly with traders and analysts to translate needs into dashboards, utilities, and business-intelligence applications.

• Ensure data quality, robustness, and reliability across all internal tools and workflows.

Requirements

• Experience building and maintaining ETL pipelines

• Solid knowledge of SQL and relational databases

• Familiarity with Git and version control best practices

• Experience developing REST APIs (Flask, FastAPI, or similar)
