Susquehanna at CppCon 2026

Susquehanna is proud to serve as the Platinum Sponsor of CppCon 2026, reflecting our continued investment in the technologies, people, and ideas shaping the future of high-performance systems.

Joining Susquehanna at CppCon will be Dr. Bjarne Stroustrup, creator of C++ and Technical Fellow at Susquehanna. In his role, Dr. Stroustrup works closely with our engineering teams on the continued advancement of our C++ infrastructure, advising on modern C++ standards, software architecture, and engineering best practices.

Andy Webber, Trading Systems Tech Lead at Susquehanna, will also present What can C++26 reflection do for you? A practical experiment in using reflection with an emphasis on binary protocol support at the conference.

Susquehanna is also supporting the conference’s Meet the Presenters Banquet and looks forward to connecting with developers from across the global C++ community throughout the week.

Build high-performance systems with us

We are hiring C++ software developers to design and develop low-latency trading systems. You’ll work directly with traders, quantitative researchers, strategy developers, and other technologists to turn complex trading problems into innovative, scalable, and stable systems.

At Susquehanna, you will:

• Make a direct impact on the systems supporting our trading desks
• See new ideas and functionality move into production through short development cycles
• Investigate and propose technologies that advance our engineering capabilities
• Develop solutions optimized for performance, stability, and scale

Prior experience in proprietary trading or financial services is not required for many of our roles. We’re looking for curious, relentless problem solvers who want to continue learning, experimenting, and growing.
