We are hiring talented engineers to join our elite Strategy Development team. This is a computationally intensive role that will allow you to utilize both your data analysis and technology skills.

As a part of this team you will be on the front lines of the business iterating with quants and traders to enhance, refine, and evolve strategies.

  • Enhance alpha generation and improve our strategy and research infrastructure.
  • Tap into tens of petabytes of raw and well-prepped full tick market data, strategy decisions, fundamentals, and many other data sources to understand market dynamics and find new signals
  • Take advantage of rapid turnaround cycles, where you’ll see the efforts of strategy ideas implemented into production quickly

What We're Looking For

  • 3 years of progressive industry experience developing performance sensitive code in C
  • Expertise in C is required
  • Experience with distributed systems and microservice architecture
  • Strong numerical programming or HPC experience
  • Prior experience working with C# or Python is a plus
  • Prior experience leading a team or driving architecture decisions preferred
  • Minimum of a Bachelor's degree in Computer Science, Mathematics or closely related discipline (Ideally MS or PhD)
