• Data Management: Solid grounding in relational database design and query structure (e.g., PostgreSQL or similar).

• Education: Bachelor’s degree in Computer Science, Computer Engineering, or a related technical discipline.

• Collaboration: Clear written and verbal communication skills for effective technical alignment across research and trading teams.
