Job Description


The Opportunity:

Founded in 1937, Mesirow Financial is a private, independent and majority employee-owned firm with approximately 500 employees headquartered in Chicago, with offices in New York, Boston, Miami, San Francisco, London and Hong Kong.

Our Currency Management Division has approximately $80 billion in assets under management and delivers innovative, customised solutions to suit client needs – ranging from passive to active currency management. Our active alpha models have a 14-year track-record of outstanding risk-adjusted performance.  In the currency alpha group, we employ a diversified collection of systematic trading models that encompass momentum, mean-reversion, statistical pattern recognition and relative value trading.

We mix mathematics, computer science, statistics and engineering with large amounts of data to understand and predict the financial markets, in particular the foreign exchange markets.  We are a research led organisation, utilising the latest technology to implement our trading and risk models for our clients and investors. We have a collaborative, scientific approach with a focus on robust peer review and rigorous in-sample and out-of-sample performance analysis to ensure the new models we develop add to the existing collection of models that have a long track record of consistent, non-correlated returns.

This individual will have an opportunity to grow and have an impact on what we do.  Our culture is open, transparent and collaborative and we are actively engaged with the broader quantitative finance community through conferences and academic outreach.  This individual will help build the trading models of the future by discovering and modelling predictable structure in vast collections of financial market and related data.  This role will be based in our London office, with occasional travel required.
