Quantitative Researcher (TCA / Execution Modelling) Global Equities Role Overview We are seeking aQuantitative Researcherfocused onexecution modelling and transaction cost analysis (TCA)within a high-performance equities trading environment. This role sits at the intersection ofquant research, execution optimisation, and portfolio construction , with responsibility for building and enhancing models that directly impact trading performance across$1B+ in daily global equity notional . The position isnot an execution trading role,it is a research-driven position requiring strongalpha-oriented thinking applied to execution and market microstructure . Key Responsibilities Develop, maintain, and enhancetransaction cost models (TCA)and execution forecasting frameworks used in portfolio optimisation Analyse and modelmarket impact, slippage, liquidity, and execution riskacross global equity markets Partner closely with trading and portfolio teams tomonitor and improve execution quality Applymarket microstructure expertiseto identify inefficiencies and drive execution alpha Contribute toalpha research initiatives , particularly where execution signals or microstructure insights can provide edge Work with large-scale trading datasets to buildrobust, data-driven modelsfor cost prediction and optimisation Continuously refine processes to improvescalability, accuracy, and performance of execution analytics Candidate Profile 16 years of experience as aQuantitative Researcherin a buy-side environment (preferred) Strong candidates fromasset managers / long-only firmswith relevant experience also considered Exceptional candidates fromsell-side trading deskswill be considered Strong academic background in aquantitative discipline(e.g. Mathematics, Physics, Computer Science, Engineering) Required Skills & Experience Strong understanding ofequity market microstructure(order books, liquidity, impact, execution strategies) Experience building or working withtransaction cost models / execution analytics Demonstratedresearch experience (alpha or signal development)not purely execution/trading Proficiency inPython and/or other quantitative programming languages Experience working withlarge, high-frequency datasets Strong statistical and modelling skills Nice to Have Experience integrating execution models intoportfolio optimisation frameworks Exposure tosystematic trading or quant equity strategies Key Differentiator This is aresearch-first role , not an execution seat.
