  • Event-driven and activist investing, including merger arbitrage, spin-offs, activist campaigns, and the identification of corporate catalysts.
  • Macro and quantitative strategies, such as systematic trading, factor research, and discretionary macro approaches.
  • Your contributions will directly impact the development of AI that can assist in identifying investment opportunities, assessing risks, and formulating strategies with greater efficiency and accuracy.
  • This is a remote, asynchronous contract role, offering flexibility while demanding a minimum commitment of 15 hours per week.

  • A key aspect of this role involves the ability to distill complex financial reasoning into clear, actionable insights for AI training. This requires not only deep domain expertise but also excellent communication skills, particularly in written form.
  • You will be instrumental in helping the AI understand the nuances of market dynamics, company valuations, creditworthiness, and macroeconomic trends as they relate to hedge fund strategies.
  • This is an exceptional opportunity to apply your extensive financial acumen in a novel and impactful way, contributing to the future of AI in the investment world.
