  • Overview

    Susquehanna International Group (SIG) is a 30 year-old privately held trading firm located just outside of Philadelphia, PA. Building virtually all of our own trading technology from scratch, we are leaders and innovators in high performance trading.


    As a Windows Engineer at SIG, you will have direct impact on the current and future structure of our multi-thousand server environment. You will have the opportunity to collaborate directly with business and technical teams, while building and deploying next generation platforms using cutting edge technologies. You will also research, design and implement solutions to enhance our applications, operating systems, and physical set up of our servers in our large cluster environment. We value an innovative and creative approach to solving the complex problems of performance and scale.


    About SIG technology

    • We love to use technology to make our lives easier. We focus on a combination of integrating automation tools and scripting our own solutions. We offer the opportunity to build on current scripting skills, as well as learn new languages. 
    • There is constant opportunity to explore new ideas and products. You will get to work with a mix of software and hardware, including the newest processors and chassis, as well as different Microsoft and OpenSource technologies.
    • Optimization is our goal. We are given the flexibility to implement and customize third party tools. We also develop and mold our own tools internally. Whether we’re increasing our speed or capacity, or decreasing our latency, we’re driven to make our systems work better and smarter. 
    • Our engineers tackle a variety of responsibilities. Whether the task is creating a script, customizing a build template, fixing a bottleneck, or researching a new project you will remain hands on while working in a challenging environment.
    • We interact directly with the business units we support to improve the trading applications and backend systems on which they depend. Our focus is to ensure they are effective, fast and have a very low chance of failure. We are always looking to identify potential problems so we can create solutions before they occur.

    What we’re looking for

    • Bachelor's degree in technical discipline required
    • Must have a solid understanding of Windows operating system (Server 2008 R2 and above), server hardware (x86 based) and networking fundamentals (TCP/IP, RDMA, CIFS/SMB)
    • Experience with performance optimization, root cause analysis, and advanced troubleshooting. Examples include familiarity with sysinternals toolset (perfmon, xperf, iperf, process explorer), as well tools such as WinDbg, and netmon.
    • Scripting and automation experience with MS PowerShell or similar scripting language strongly preferred
    • Experience with or understanding of virtualization technologies such as VMWare and Citrix preferred
