Job Description

Overview

Susquehanna is seeking a Software Developer to join a team responsible for designing and developing low-latency trading systems for our Index Desk. As a developer on this team, you will work closely with traders and top technologists to enhance our trading capabilities by providing innovative, scalable and stable systems.We are looking for a strong C++ Developer with experience in performance and optimization.

In this role you will:

  • Have a direct impact on a successful desk working directly with traders
  • Propose new ideas or gather requirements for additional functionality, both of which are brought into production quickly through our short development cycles.
  • Have the opportunity to propose and investigate new technologies to help us stay ahead.

What you can expect from us:

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: You will partner closely with our Strategy Developers and Quantitative Researchers to translate complex trading problems into scalable and highly performant hardware 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 or HFT infrastructure.
  • Experience with object oriented design and software development in a high-performance / high throughput environment using C++ (preferably in a Linux environment) is required
  • Excellent attention to detail and accuracy and a thorough understanding of full life-cycle development and performance optimization / latency reduction methodologies.
  • Ability to work closely with other software developers, traders, quants, and infrastructure teams
