Add expected salary to your profile for insights.
As a Network Expert, you will lead the design and optimization of global trading system network architectures, resolving extreme network complexities to ensure cross-border low-latency trading stability and security. You must possess deep expertise across cloud providers, dedicated lines, and security domains while providing technical leadership to the team.
Job Responsibilities:
* Global Network Architecture Design & Optimization:
• Design multi-region Active-Active trading architectures using AWS Transit Gateway and Direct Connect, ensuring cross-region failover with ≤3ms latency.
• Implement Traffic Engineering to bypass congested international ISP nodes (e.g., Telia, NTT) and optimize Tokyo-London-New York trading paths.
• Integrate third party low-latency dedicated lines with AWS Global Accelerator, dynamically adjusting BGP weights to handle market volatility.
* Complex Incident Resolution:
• Lead P0-level incident recovery (e.g., submarine cable outages, route blackholing) using path analysis tools and Wireshark packet capture to achieve MTTR ≤15 minutes.
• Develop Python/Go automation scripts to trigger failover to backup links when packet loss exceeds 0.1%, preventing trading cascades.
• Conduct simulated cross-border network failure drills to validate redundancy and refine SOPs.
* Security & Compliance:
• Build Zero Trust Architecture with AWS Network Firewall and Calico policies to isolate core trading zones from public services.
• Design DDoS mitigation strategies leveraging AWS Shield Advanced and Third party’s global scrubbing centres to withstand > 1 Tbps attacks.
• Ensure GDPR/MAS TRM compliance by auditing cross-border data flows via VPC Flow Logs and generating compliance reports.
* Emerging Technology Adoption:
• Explore SRv6, Segment Routing, and FPGA-accelerated TCP/IP stacks to reduce latency and dependency on dedicated lines.
Job Requirements:
* Minimum 8 years in network architecture, with 5 years focused on low-latency financial systems (e.g., crypto/FX HFT platforms).
* Experienced in leading at least 3 cross-border trading system migrations and resolved complex outages (e.g., BGP route flapping).
* Mastery of AWS networking (Transit Gateway, Direct Connect, VPC Flow Logs) and dedicated line optimization.
* Proficient in path diagnostics, global node monitoring and packet-level analysis.
* Python/Go scripting for BGP automation and traffic engineering.
* Certifications: AWS Certified Advanced Networking - Specialty (required), CCIE Enterprise Infrastructure/JNCIE-SP (carrier-grade networking), CISSP/CISM (preferred for security compliance).
