Job Description

Overview

Susquehanna International Group is seeking an experienced Software Developer to join a Front Office team responsible for designing and developing prediction market trading systems.

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:

  • Execute on ideas quickly
  • Commit to innovation
  • Focus on the entire technical stack with an eye for building a stable, scalable, optimized environment with minimized risk
  • Work with traders and quantitative researchers to build, maintain, and improve order sending prediction market strategies
  • Explore new technologies to find the optimal solution
  • Exercise strong object oriented programming skills

What you can expect from us:

Real Impact: You'll be designing and optimizing systems that process massive amounts of data, ensuring high performance and stability. 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: Susquehanna 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
  • 5+ years of progressive experience developing software applications
  • Familiarity with financial markets or prediction markets is a plus
  • 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

About Susquehanna

We have incorporated this approach into our culture, where you will find relentless problem solvers within each of our core disciplines: Trading, Technology, and Quantitative Research. From offices around the world, our employees collaborate to make optimal decisions and are driven by the desire to achieve winning results together.

What we do

We are experts in trading essentially all listed financial products and asset classes, with a focus on derivatives trading. Through market making and market taking, we handle millions of trading transactions around the world every day, providing liquidity and ensuring competitive prices for buyers and sellers.
