Responsibilities
Transport and Congestion Control: Design, implement, and optimize protocols and controllers—spanning TCP, RDMA, and hybrid transports—to deliver high throughput, low latency, and fairness across massive data center networks
Telemetry: Develop and integrate robust telemetry systems to provide continuous, fine-grained visibility into transport performance, congestion, and overall network health
System Implementation: Contribute to the reliability, performance, and operational excellence of congestion management, telemetry, and security components within OCI’s stack
Protocol Optimization: Advance algorithmic solutions for efficient transport and congestion control at both host and switch levels, ensuring seamless interplay between protocols and infrastructure
Performance Troubleshooting: Use advanced diagnostic tools to analyze protocol behavior, buffer utilization, network bottlenecks, and implement corrective actions at scale
Production Delivery: Validate and deploy new features and enhancements across OCI’s large-scale deployments, collaborating closely with hardware, host networking, telemetry, and SRE teams
Collaboration and Best Practices: Share insights, review designs, and drive adoption of best practices for telemetry, security, and transport optimization across the engineering organization
Continuous Learning: Stay current with developments in network transport, telemetry, security, and data center networking, rapidly applying new techniques for production benefit
