  • Programming: Strong proficiency in Python and SQL, supported by graduate coursework, research, internships, or substantive technical projects.
  • Data Skills: Experience working with large, structured or unstructured datasets, along with a strong understanding of data validation, transformation, analysis, and reproducible research.
  • Development Foundation: Solid understanding of object-oriented programming, modular design, testing, version control, and maintainable software-development practices.
  • Problem Solving: Strong analytical judgment, attention to detail, intellectual curiosity, and the ability to work independently through open-ended quantitative and technical problems.
  • Collaboration: Ability to communicate clearly, receive feedback, document work, and contribute effectively in a team environment.
  • Investment Interest: Interest in quantitative finance, investment management, financial markets, or the application of technology to investment research.
