Quantitative Portfolio Manager Jobs (NOW HIRING)

THE TEAM

Man Group's quantitative investment engines, AHL and Numeric, are aligning under Systematic (USD ~138bn AUM). As part of this integration, we are expanding our Investment and Data Implementation (IDI) team, which has supported AHL for many years, into a new Boston-based team supporting the Man Numeric business.

The global IDI team spans Hong Kong, Sofia, London and now Boston. The Boston team is responsible for implementing all new business and portfolios (funds, Separately Managed Accounts (SMAs), and investment strategies), maintaining the integrity of systematic models, and steering the long-term development of our trading initiatives. Our mission is to ensure every quantitative strategy is implemented with precision and aligned with its investment objectives, from initial research idea through to the last trade. Though Boston-based and focused primarily on Man Numeric's content, as part of Systematic, you will be part of a connected global network, sharing tooling, codebase, and implementation capabilities across all four locations.

The problems the team solves are diverse, complex, and high-impact. The team is the primary responder when production issues halt the investment managers, requiring rapid diagnosis and resolution without introducing new risks. The team are the operational architects who translate a researcher's ideal strategy or portfolio into a robust, scalable solution, balancing speed, resilience, and business logic. The team also works closely with other areas such as Portfolio Management and Trading to explain why an algorithm and portfolio optimizer generated specific trades. Finally, we partner with technologists to help design trading architecture that is automated, scalable, and transparent enough for manual intervention when necessary.

This role offers exceptional exposure. Man Group's flat structure means your work is widely visible across the group, you will be working with portfolio managers, quantitative researchers, product structuring specialists, and traders, with the opportunity and expectation to contribute, propose solutions, and make decisions regardless of seniority. You'll be supported throughout and as you build confidence, you will represent the global IDI team on cross-departmental working groups and present findings directly to senior management.

THE ROLE

We are seeking a highly motivated professional to bridge quantitative research, portfolio management, technology, trading, and middle & back-office teams.

The analyst will partner with portfolio managers on the day-to-day operations of portfolio management, and collaborate with researchers, engineering, trading, and Man Group operations to ensure portfolios are managed accurately and our investment management infrastructure runs as intended. Time-sensitive daily production tasks are managed via a team rota, allowing off-rota time to be protected for deep-dive project work, coordinating complex fund and SMA launches, data analysis, prototyping new tooling and processes, and building out the team's AI capability.

You will operate with a high level of autonomy. Our goal is to build your knowledge of the entire systematic investment management process (from Equity Long Only and Equity Market Neutral, Fixed Income to Multi-Strategy and Global Macro) and the investment philosophy driving Systematic, empowering you to identify challenges, evaluate solutions, and deliver improvements and innovation independently.

Key Responsibilities:

Portfolio implementation:

• Implement high-impact, real-time changes to the investment management and trading environment, including rolling out new quantitative research, launching new products, managing client and other constraints, and refitting existing products and strategies.
• Orchestrate and coordinate the investment process for new fund and complex SMA launches, ensuring clear ownership across front-office and central functions

Portfolio operations:

• Design and implement the new operating model for Equity Market Neutral, Equity Long Only and Fixed Income for IDI Boston
• Perform daily portfolio monitoring, manage compliance/constraint updates, and facilitate pre-trade order vetting alongside Portfolio Managers
• Manage and coordinate daily client flows (rebalancing, allocations) in close collaboration with Portfolio Managers
• Act as primary responder for production and trading issues across the systematic investment management estate and portfolio construction environment, leveraging smart tooling and, increasingly, AI and agentic workflows to diagnose root causes and execute manual workarounds for timely risk management

Implementation analytics and improvement:

• Actively embrace and build AI skills and agentic workflows to pull relevant context, provide smart monitoring, and drive self-healing capabilities within the production system
• Work alongside peers across Systematic to define and deliver resilient trading system and platform development
• Use data analytics (Python/SQL/Pandas) to investigate complex scenarios - from simulating market restrictions to analysing exchange limit utilisation to validating strategy refits against production baselines
• Develop implementation analytics to provide commercial insights for the business

SKILLS AND ATTRIBUTES

The role relies on strong attention to detail, analytical judgement, and strong stakeholder management. Technical proficiency (e.g. Python, SQL) is highly valued, though we are equally interested in candidates keen to learn these skills and use emerging AI capabilities to drive efficiency.

Essential:

• Ability to manage complex projects and multiple priorities simultaneously in a dynamic, fast-paced business
• Excellent attention to detail and a highly collaborative personality
• Driven and proactive. As a foundational member of the Boston team, you must be comfortable working without a perfect playbook and possess the initiative to build and refine processes from scratch
• A keen analytic approach to problem-solving, distilling complex problems to enable timely resolution
• Strong verbal and written communication; the ability to interact confidently with portfolio managers and domain experts
• Dependable judgment under pressure
• A relentless focus on delivering value to the business and improving implementation processes

Advantageous:

• High level understanding of quantitative investment processes and portfolio construction
• Experience with portfolio management and/or trading systems, along with proficiency in data analysis and process automation
• Experience delivering or steering complex projects, such as fund or Separately Managed Account (SMA) launches
• Commercial experience or a strong interest in using AI tools to drive workflow efficiency and business insights
• Generalist experience and exposures within buy-side systematic investment (Implementation, Front Office, Middle Office or Trade Operations)
• Ability to use SQL and an object-oriented language (preferably Python) to investigate data and prototype solutions
• Proficiency in data reasoning techniques and relevant libraries (e.g., Pandas)
