- Strong expertise in systems programming, memory management, and CPU architectures.
- Deep knowledge of Linux internals, kernel parameters, and low-level profiling.
- Passion for high-performance computing, networking, and hardware-software optimization.
- Experience in systematic trading, HFT, or quantitative environments is a plus.
- Proven ability to architect, optimize, and scale ultra-low-latency systems.
