About the Job

Requirements

  • A Master's degree or equivalent in Mathematics, Computer Science, Statistics, Finance, or a related field; alternatively, a Bachelor's degree or equivalent in one of those fields plus three years of experience in quantitative analysis or related experience.
  • Experience developing quantitative trading strategies, including feature engineering, signal construction, backtesting, and portfolio simulation.
  • Experience with predictive modeling techniques, including linear models, regularization methods, tree-based models, neural networks, and ensemble methods.
  • Experience with large-scale data processing and distributed computing using cloud infrastructure for parallelized data loading, model training, and simulation.
  • Experience conducting empirical research, including formulating hypotheses, structuring experiments, diagnosing confounding variables, and iterating on results.
  • Experience performing financial data analysis and alpha research on fundamental, technical, and market microstructure data.
  • Experience with scientific programming using data manipulation, machine learning, and visualization libraries.
  • Experience with engineering practices including version control, code review, and scalable research pipeline design.
  • Experience with quantitative analysis methods including cross-sectional and time-series analysis and hypothesis testing.
  • Experience with performance attribution, including decomposing model outputs across market segments, time periods, and regimes to identify sources of alpha, diagnose degradation, and guide iterative model improvement.
  • Pass the company's required skills assessment.

Responsibilities

  • Develop and evaluate quantitative equity investment models using statistical and machine learning techniques, including linear models, regularization methods, tree-based models, and neural networks, to generate predictive trading signals across multiple return horizons.
  • Collaborate with portfolio managers and domain experts to formulate investment hypotheses and alpha ideas, translating market intuitions into testable quantitative signals.
  • Engineer features from large-scale data sources including equity fundamentals, analyst forecasts, corporate earnings events, and market microstructure data across intraday and overnight trading sessions.
  • Construct and evaluate event-driven, composite, and cross-sectionally propagated alpha signal strategies, performing post-processing such as risk factor residualization and decorrelation against existing signals.
  • Analyze cross-sectional and time-series relationships across market segments, identifying variation in signal strength by market capitalization, liquidity, volatility, and industry classification.
  • Perform exploratory data analysis and statistical testing to validate investment hypotheses, characterize information flow dynamics, and assess the predictive content of novel data sources.
  • Design and implement end-to-end scalable research pipelines in Python for distributed data processing, parallel model training, and automated experiment management using cloud computing infrastructure.
  • Process and analyze very large financial datasets using distributed computing frameworks, optimizing data loading, storage, and computation for efficient research iteration.
  • Evaluate signal quality and portfolio performance through information coefficient analysis, Sharpe ratio estimation, return attribution across market segments, and optimizer-based portfolio simulation with transaction cost modeling.
  • Collaborate with engineers to implement and test quantitative investment ideas in production-scale systems and shared research frameworks.

About the Company

Two Sigma

Quantitative finance firm building predictive models

Two Sigma is a financial sciences firm that uses data analysis, rigorous inquiry, and invention to tackle complex problems in investment management, securities, private equity, insurance technology, and venture capital. Its product approach centers on building sophisticated predictive models powered by extraordinary computing power and vast data. Modelers and engineers test ideas with information and iterative improvement to drive progress. Compared with many peers, Two Sigma differentiates itself through a data-driven, model-centric investment process that relies on large-scale computing and extensive datasets rather than relying on traditional methods alone. The company aims to solve the toughest challenges in its fields and advance investment outcomes by continuously refining predictive models through experimentation.
