Data Quality Engineer
<p data-renderer-start-pos="32" data-local-id="816ffa3f23f5">At <span data-highlighted="true" data-vc="highlighted-text"><span data-testid="definition-highlighter">IMC</span></span>, data shapes trading decisions across a wide range of financial products. The Data Quality team owns the integrity, completeness, and timeliness of the datasets our Quantitative Researchers and Traders rely on. As a Data Quality Engineer, you design the statistical methods that detect, characterise, and quantify issues in those datasets. Additionally, you own historical datasets that turn raw vendor and internal feeds into pricing-grade inputs and output.</p>
