- Collaborate with cross-functional security, technology, and trading teams to design and deploy innovative solutions that enhance both system integrity and trading performance.
- Actively contribute to the design, implementation, and maintenance of mission-critical trading infrastructure that drives resilient and scalable market operations.
- Implement robust strategies to reduce network risks by leveraging micro-segmentation, port-based security, and other innovative methods.

- Perform in-depth analysis of network packet captures to investigate security incidents and identify areas for improvement.
