Working closely with quantitative researchers, analysts, portfolio managers, and data engineering teams, the successful candidate will gain hands-on experience developing practical solutions used across investment workflows.

Key Responsibilities

  • Research Platform Development: Help build and enhance tools, libraries, and frameworks for security forecasting, quantitative research, factor modeling, portfolio analysis, machine learning workflows, and portfolio analytics.
  • Data Engineering & Integration: Support pipelines that ingest, validate, transform, and distribute financial datasets; contribute to data-quality, integrity, and reliability checks.
  • Application & Tool Development: Develop dashboards, APIs, utilities, and analytical applications that improve research and portfolio-management workflows.
  • Research Implementation: Work with researchers and analysts to translate models, forecasting signals, and analytics into reliable, reusable, and well-documented code.
  • Cloud & Infrastructure: Assist with deployment, automation, monitoring, and operational support for quantitative solutions in cloud or on-premises environments.
  • Software Engineering Practices: Participate in code reviews, testing, documentation, version control, and CI/CD workflows to improve reliability and reproducibility.
  • Cross-Team Collaboration: Gather requirements and deliver practical technology solutions in partnership with investment and technology professionals.
  • Continuous Improvement: Explore new development frameworks, data tools, and quantitative technologies that may improve team capabilities and efficiency.

Candidate Profile

  • Education: Currently enrolled in a Master’s or PhD program in computer science, software engineering, mathematics, financial engineering, quantitative finance, data science, statistics, or a related field.
  • 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.

  • Machine Learning: Graduate coursework or research experience involving machine learning, statistical modeling, experiment tracking, or model deployment concepts.
  • Financial Technology: Experience with financial datasets, forecasting models, portfolio analytics, risk models, or investment systems is an asset, but not required.

What the Graduate Student Will Gain
