• Design and build low-latency, high-availability trading systems
• Develop exchange connectivity, market access, and order routing infrastructure
• Build and enhance OMS and real-time trading platforms
• Optimize performance across latency-sensitive C++ applications
• Partner directly with portfolio managers, traders, and quantitative researchers
• Contribute to architecture and technical decisions across a growing systematic technology platform
• Own projects end-to-end, from design through production deployment

What We’re Looking For

• Deep understanding of algorithms, data structures, and systems design
• Strong Linux and networking fundamentals
• Experience with multithreading, concurrency, and performance optimization
• Background in trading technology is beneficial but not required
• Bachelor's degree in Computer Science, Engineering, Mathematics, or a related field

Additional Notes
