Designing and developing system architecture:

·        Core trading systems and algorithmic trading frameworks

·        High-performance execution algorithms for global markets

·        Exchange simulators and tick-level backtesting frameworks

·        Market data adaptors and exchange connectivity adaptors

Building from scratch:

·        Trading systems for new asset classes and execution algorithms

·        Performance optimizations for low-latency, high-throughput systems

Enhancing existing systems:

·        Add support for new features and improve scalability and reliability

Collaborating closely with:

·        A global team of quants, traders, and senior engineers to design cutting-edge solutions

Analyzing and optimizing system performance:

·        Across application, OS, and hardware layers to achieve industry-leading performance

·        Work primarily with C++17 in a high-impact, low-bureaucracy environment

Requirements
