About the role
Develop and productionize quantitative investment models and research tools, partnering with portfolio managers and researchers on signals, asset allocation, optimization, portfolio construction, rebalancing, and attribution. Own the multi-asset data layer and the reliability, testing, monitoring, documentation, and AI-enabled workflows of the systems delivered. Candidates must have built enterprise-quality quantitative or systematic models from specifications, deployed them to production at meaningful scale, and taken responsibility for their operational performance. They should be familiar with the software development lifecycle, be heavy users of modern AI coding tools, and have extensive experience documenting model implementations; financial markets, econometrics, statistics, version control, CI/CD, and cloud experience are advantageous.
