Robeco is looking for a Trading Researcher to strengthen its equity trading desk. Lower cost through data-driven trading decisions. Research, develop and maintain models that assist our traders in achieving the best possible execution for Robeco’s strategies.
Robeco is an institutional asset manager with more than one hundred billion of assets under management for several equity investment strategies. Each investment strategy creates orders that are executed by Robeco’s equity trading desk using execution algorithms serviced by brokers. These algorithms split the order into smaller pieces so that the entire order is executed slowly over, e.g., the course of the day.
The main driver of execution costs is market impact, which is the adverse effect that trading has on the price, i.e., moving the price up when buying and down when selling. Your primary objective is to make our execution decisions data driven, and, thereby, lower market impact cost.
In this role, you will develop market impact models, develop forecasting models for market volume and volatility, assess performance of different execution strategies, and optimize execution strategies. Major challenges include the low signal-to-noise ratio typically encountered in market data, dealing with large data sets, and developing advanced quantitative models.
Research shows that female candidates only apply if they meet 100% of the requirements, while male candidates already do so at 60%. Are you hesitant about whether you meet all requirements? Please do apply, we’re looking forward to hearing from you.
How we think about AI in this role
AI literacy is part of effective data-science work, but it is not a substitute for subject knowledge or quantitative judgement. We are looking for someone who can select appropriate tools, formulate good questions, inspect generated code or text critically and verify results against reliable sources and tests. Experience with AI coding assistants, large language models or automated document analysis is welcome, but deep AI specialization is not required.
In your cover letter, please describe how you would take on the challenge explained below:
Our traders suspect that we get adversely selected, when trading on a certain block trading venue, i.e., a venue where your order is invisible until someone else wants to do a large trade with you. We have a rough idea of how execution on this venue works, and have a limited data set with our executions, but probably not enough to reach statistical significance. How would you address this challenge and assist our traders in the best way forward?
How to apply
Interested in this position? Please send us your cv, a grade list, and cover letter with your motivation plus response to the challenge.
Be aware that incomplete applications will not be considered.
All applications will be treated with the utmost confidentiality. An assessment and integrity test may be used in the selection procedure.
