About the Role

A collaborative and entrepreneurial systematic macro pod is seeking an experienced Quantitative Developer with a machine learning focus to develop and deploy machine learning models on high-frequency market data, and build the research and compute infrastructure behind them.

Responsibilities

  • Design, train and productionize large-scale machine learning models across both classical and deep learning approaches, applied to high-frequency data
  • Enhance and optimize the pod’s end-to-end machine learning pipeline, from large-scale data processing and distributed computation to scalable parameter search and validation
  • Contribute to improving the speed, scalability, and reliability of the pod’s wider signal development environment, ensuring consistent and efficient migration from research to production
  • Partner with broader technology teams to make effective use of shared internal platforms and Services

Requirements

  • Master’s or PhD/Post doctorate in Computer Science, Mathematics, Statistics, Engineering, Physics, or a related quantitative discipline, from a leading institution
  • 3+ years of professional experience in software engineering, quantitative development, or a related computational role
  • Experience developing and validating machine learning models on large, complex datasets, across both classical and deep learning approaches, in industry or academia
  • Experience building distributed computing systems for machine learning applications
  • Strong Python programming skills beyond the standard research stack — parallelism, distributed compute, and native acceleration such as Python or C++ bindings
  • Familiarity with C++ is a strong plus, alongside the software engineering fundamentals to pick it up quickly
  • Experience building data-intensive tools, research workflows, or model development infrastructure
  • Strong Linux development experience
  • Experience building agentic AI systems — tool use, orchestration, and evaluation
  • Experience with backtesting and awareness of common research pitfalls such as overfitting, lookahead bias, and survivorship bias
