About the role

  • You will work in a tight feedback loop with our Quantitative Technologists.

Responsibilities

  • Risk Management: Developing robust covariance matrices and risk constraints to ensure survival and profitability during "black swan" events or volatility shocks.
  • Protocol Optimization: Collaborating with engineers to reverse-engineer exchange behavior and optimize order placement logic for specific frontier venues.
  • At K4, research outcomes drive more than just risk-adjusted returns.
  • We design and deploy the financial infrastructure that powers modern markets, partnering with leading research organizations to solve engineering problems at a global scale.

Requirements

  • Advanced Degree: Ph.D. or M.S. in a quantitative field (Physics, Mathematics, Statistics, Computer Science, or Electrical Engineering).
  • Implementation Skills: Proficiency in C++ or Rust is highly desirable.
  • We value raw analytical horsepower and the ability to apply it to open-ended problems.
  • Scientific Computing: Fluency in Python (NumPy, SciPy, Pandas) for data analysis and research.
  • Implementation Skills: Proficiency in C++ or Rust is highly desirable. At K4, researchers are expected to understand the production systems their models run on.
  • Statistical Rigor: A deep understanding of probability theory, linear algebra, and regression analysis. You should intuitively understand the dangers of overfitting and look-ahead bias.
  • We are looking for individuals with a fierce intellectual curiosity and a "first-principles" approach to problem-solving. We value raw analytical horsepower and the ability to apply it to open-ended problems. To apply, please submit your Resume/CV and, if applicable, a link to your research portfolio (SSRN, arXiv) or GitHub. We are particularly interested in research that demonstrates creativity in data selection and rigorous methodology.
