• Build real-time infrastructure that supports quoting, pricing, and order execution

• Work closely with traders and quants to turn strategy into robust, production-ready code

• Optimise code paths for throughput and speed, from hardware to exchange connectivity

Requirements:

• 2 - 5 years of professional experience with modern C++ (minimum C++17) and system-level programming

• Solid understanding of computer architecture, OS internals, and networking fundamentals

• Background or keen interest in competitive programming (IOI, ICPC, Codeforces, etc.)

• Strong problem-solving ability and the drive to work in fast-moving environments

• Prior experience in trading not required, but a genuine interest is essential
