As a developer on this team, you will work closely with traders and technologists to enhance our trading capabilities by providing innovative, scalable and stable systems. You will have direct impact on a successful desk and work directly with traders on proposing new ideas or gathering requirements for additional functionality, both of which are brought into production quickly through our short development cycles.  Beyond development, you will have the opportunity to propose and investigate new technologies to help us stay ahead. We are looking for an experienced C++ Developer with experience in performance and optimization.


In this role, you will:

You’ll see how your contributions towards developing and supporting leading-edge hardware and software solutions make a firm-wide impact that makes us all smarter, faster, and better.

Collaboration: Our systems engineers, network architects, technical analysts and software developers work together to create competitive edge through best-in-class technical solutions.

Growth: For many of our roles, we don’t expect you to have prior industry experience in proprietary trading or financial services to succeed at Susquehanna International Group. We’re looking for people who are naturally curious, relentless problem solvers, and have the desire to continuously innovate, learn, and grow.

Benefits: SIG offers a wide array of competitive employee perks & benefits.

What we're looking for
  • Bachelor's degree in Computer Science, Engineering, Mathematics or related discipline or its foreign equivalent
  • 10+ years of progressive experience developing software applications or HFT infrastructure

  • Excellent attention to detail and accuracy and a thorough understanding of performance optimization / latency reduction methodologies
  • Ability to work closely with other software developers, traders, quants, and infrastructure teams
