Job description

Who You'll Work With

ABs systematic merger arbitrage strategy sits within Multi-Asset & Hedge Fund Solutions, a team known for combining quantitative rigor with deep market expertise. You will report directly to the Head Portfolio Manager, a 30-year veteran of discretionary event-driven investing and serve as his primary research counterpart and deputy on the portfolio. You will collaborate closely with ABs technology and data engineering teams, who provide infrastructure support, freeing you to focus on research, signal development, and investment decision-making. You will also engage directly with ABs institutional clients and prospects, representing the strategy in meetings and contributing to business development alongside the Head PM and the broader client group.

What You'll Do

Systematic Research & Signal Development

Identifying patterns in active and completed deals that can be systematically tested against historical data. Design and maintain quantitative models and systematic signals to assess spread dynamics, deal break probability, and portfolio-level risk and return behavior. Develop, backtest, and evaluate new investment ideas using the team's backtesting engine; own the integrity of input data and the deal database that underpins this process, ensuring completeness, accuracy, and consistency of historical and live deal records. Identify and apply machine learning and statistical techniques to extract signals from deal, market, and alternative data. Proactively identify opportunities to leverage AI tools across the strategy — including data acquisition, deal monitoring, and research workflows — and help embed those capabilities into the team’s day-to-day investment process.

Portfolio Management Support

Monitor and assess active deals across the M&A universe — tracking deal timelines, deal structure, regulatory and antitrust developments, and deal outcomes. Periodically engage with company management teams and deal advisors as needed to clarify deal timelines, assess regulatory risk from the issuer’s perspective, and confirm deal economics where contractual terms require interpretation for modelling purposes. Track regulatory filings (HSR, SEC), antitrust proceedings, shareholder vote schedules, and deal timetables for all active positions. Support the Head PM in position sizing, portfolio construction, and risk management decisions. Assist with trade building and portfolio monitoring. Contribute to regular strategy performance reviews, providing attribution analysis and research-driven commentary on historical results.

Technology & Data

Partner with ABs technology team to enhance research workflows, data pipelines, signal construction, and analytics. Manage deal and market data across relational databases; maintain data quality standards across all research inputs. Identify opportunities to expand the team’s data capabilities through alternative or third-party data sources.

Client & Business Development

Attend meetings with institutional clients and prospects to present the strategy, discuss current positioning, and present research findings — including deal-level analysis and systematic insights from the team’s backtesting work. Contribute to the preparation of investor materials, performance commentary, research publications and the strategy’s quarterly investment letter. Serve as a credible and articulate spokesperson for the strategy in client interactions and external forums.

What We’re Looking For

• 5+ years of investment management or quantitative research experience in equities. Experience with merger arbitrage or event-driven strategies a plus. Experience with quantitative research methods, including backtesting systematic strategies and evaluating signal performance Working proficiency in Python for research and data analysis purposes; comfort writing and maintaining production-quality scripts in an investment context. Working proficiency in SQL for querying and managing structured datasets. Excellent attention to detail and a strong commitment to data quality.

Preferred

• Familiarity with Merger Arbitrage. Ability to analyze M&A transactions from announcement through close, including an understanding of typical deal timelines, deal structures, regulatory review processes, and break risk.


• Experience with quantitative modeling and ML methods applied to event-driven or arbitrage investing (e.g., classification models, supervised learning for deal outcome prediction).


• Exposure to systematic strategy development: factor construction, signal combination, and portfolio optimization.


• Experience using AI tools to augment investment or research workflows; able to articulate clearly how AI has enhanced their work and to identify practical applications within a systematic strategy context.
