In this role you will

• Quantitative research for the Global Bond Index team, developing signals that are robust, implementation-aware, and relevant to portfolio decisions in a tightly controlled risk environment
• Develop quantitative approaches that support systematic portfolio construction, basket creation, and portfolio implementation across index strategies
• Identify and advance opportunities to improve trade efficiency, execution quality, and investment workflow through better use of data, analytics, and market structure insight
• Research market dislocations, liquidity and volatility risk premia in ways that can strengthen portfolio outcomes while remaining aligned with portfolio constraints and risk objectives
• Build models, tools, and analytical frameworks that support alpha generation, portfolio construction, risk management, and scalable investment decision-making
• Partner closely with portfolio managers, traders, and research stakeholders to shape priorities, refine use cases, and ensure outputs are practical and implementable
• Evaluate ideas with clear attention to transaction costs, portfolio fit, unintended exposures, operational feasibility, and expected investment value
• Contribute to both team-specific work and broader capabilities that can be applied across investment processes where appropriate
• Communicate research findings and recommendations clearly, including the investment rationale, implementation considerations, and trade-offs involved
• Help strengthen the rigor, quality, and consistency of the broader research and investment process through documentation, collaboration, and knowledge sharing

What it takes

• Strong quantitative research experience in fixed income, systematic investing, or related investment strategies
• Demonstrated ability to generate actionable investment ideas and translate them into portfolio applications
• Experience in signal research, portfolio construction, and implementation within a risk-conscious investment setting
• Familiarity with execution considerations, market microstructure, and the drivers of trade efficiency in fixed income markets
• Deep analytical and modeling skills, with the ability to connect technical work directly to portfolio outcomes
• Strong judgment in balancing innovation, rigor, implementation feasibility, and investment value
• Ability to work effectively across portfolio management, trading, research, and technology-oriented partners
• Clear communication skills and the ability to influence decisions through practical, well-structured analysis
• A track record of operating independently and delivering high-impact outcomes in complex investment settings
• Experience with Fixed Income Index or Enhanced Index strategies is a strong differentiator

Success in this role will look like

• Research insights that can be applied in live portfolio decisions for the Global Bond Index team
• Improving portfolio construction and implementation through stronger systematic insight and better execution-aware analytics
• Enhancing basket design, trade efficiency, and use of systematic tilts in support of investment outcomes
