In this role, you will be part of an early effort to build our next generation of gateways, critical exchange connectivity systems that enable us to quickly price, quote, and execute in highly competitive electronic markets.

This is an opportunity to work on high-impact systems where performance, reliability, and engineering precision directly influence trading outcomes.

How you’ll make an impact:

• Design and develop performance sensitive C++ applications that connect our trading platforms to exchanges and liquidity venues
• Engineer resilient real-time systems capable of handling massive volumes of market data and order flow
• Collaborate directly with traders, quantitative researchers, and infrastructure engineers to improve trading performance and execution quality
• Analyze system behavior and optimize latency, throughput, and determinism across the software stack
• Contribute to the architecture of next-generation trading systems supporting one of the largest options market making businesses globally

• Minimum 2+ years of experience programming in modern C++, with a focus on writing performance critical code is required
• Comfortable working in a fast-paced, collaborative environment with traders, researchers, and other developers to iterate quickly on ideas
• Knowledge of TCP/UDP networking and/or exchange facing protocols is a plus
• Prior experience in electronic trading or financial technology is a plus but not a requirement to be successful
• Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Mathematics, or related technical field

Real Impact: By integrating sophisticated coding techniques with innovative engineering ideas, we design and optimize systems that can process massive amounts of data while still ensuring high performance and stability. You’ll see how your contributions towards developing and supporting leading-edge hardware and software technologies 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.
