The role sits within the Index Research & Design team of Equities & Multi-Asset vertical, a global group responsible for the development, design, research and enhancement of index methodologies, analytics and investment solutions. The team works closely with Product, Engineering, Technology, Data Operations, Sales and key clients to deliver innovative index capabilities and analytical solutions. Team members contribute across research, product development, operational delivery and client engagement, supporting a broad range of equity and multi-asset initiatives.

We are seeking an experienced quantitative professional to join the team as a Manager, Quantitative Research & Development. This is a highly dynamic role for an individual who can seamlessly switch between quantitative research, software development, data quality, operational support and client engagement. Success in this position requires a "do what it takes" mindset, strong ownership, and the ability to rapidly reprioritise across competing demands while working with Research Analysts, Engineering, Technology, Data Operations, Product, Sales and clients.

• Develop and maintain quantitative research, analytics and automation platforms.
• Build AI-enabled workflows, tools and agents to improve research, operational efficiency and client support.
• Support quantitative research initiatives, investment analytics and index methodology development across equity and multi-asset strategies.
• Investigate and resolve complex data, analytics and operational issues while maintaining the highest standards of quality and accuracy.
• Drive improvements in research infrastructure, development processes, CI/CD practices and cloud-based solutions.
• Partner closely with Research, Engineering, Technology, Product, Data Operations and Sales teams to deliver business objectives.
• Provide analytical support and respond to internal and external enquiries relating to data, methodologies, analytics and product capabilities.
• Contribute across the full lifecycle of research and product development, from idea generation and data validation through implementation, deployment and client-facing delivery.

The ideal candidate will have approx. 10 years of experience spanning quantitative research, quantitative development, investment analytics or related disciplines. They will possess strong Python and SQL skills, experience with CI/CD, cloud computing, AI-assisted development tools (e.g. GitHub Copilot, VS Code) and modern software engineering practices. A solid understanding of equity markets and quantitative investment techniques - including regression analysis, optimisation, factor investing and risk modelling - is essential. Experience with financial databases and platforms such as Worldscope, IBES, Lipper, Datastream and Refinitiv Workspace is highly desirable. Above all, we are looking for an agile, intellectually curious self-starter who can be productive from day one, communicate effectively with both technical and non-technical stakeholders, manage multiple priorities simultaneously and thrive in an environment where the required skill set may change significantly from one day to the next.
