Responsibilities
End-to-End Congestion Management: Develop, analyze, build and deploy transport protocol controllers (hybrid, both loss-based and delay-based) for managing congestion across a variety of workloads and network conditions
System Architecture & Theory: Architect robust, scalable solutions grounded in deep understanding of transport theory and practical constraints—balancing queue management, buffer occupancy, throughput, and fairness
Protocol Design & Optimization: Advance algorithmic approaches to congestion control at both host and switch level, considering the interplay between TCP, RDMA, hybrid transport protocols, and existing network infrastructure
Performance & Diagnostics: Lead investigations into transport-level behavior at scale. Employ sophisticated diagnostic tools and methodologies to analyze network buffer utilization, link bottlenecks, and flow fairness; identify and resolve congestion hotspots
Implementation & Deployment: Guide and contribute to the implementation, integration, validation, and production rollout of novel congestion controllers and related telemetry solutions. Collaborate with hardware, host networking, SRE, and product teams on deployment at massive scale
Cross-team Influence: Serve as a subject matter expert, reviewing designs and advising other engineering groups on best practices for congestion management, data path efficiency, network scalability, and reliability
Research & Thought Leadership: Stay abreast of advances in transport protocols, actively contribute to internal knowledge sharing, and prototyping improvements to make the OCI network world class
Qualification
Preferred
Advanced degree (MS/PhD preferred) in Computer Science, Electrical Engineering, Math or equivalent, with hands-on specialization in computer networks, transport protocols, or distributed systems
10+ years of experience designing and deploying large-scale transport control protocols (TCP, RDMA, QUIC, DCTCP, CTCP, CUBIC etc.), with a strong track record of shipping production code in these domains
Deep expertise in congestion control theory (loss-based, delay-based, hybrid algorithms), network buffer management, and queuing theory
Demonstrable experience analyzing transport protocol behavior in real-world environments, optimizing for throughput, latency, and fairness
Expert knowledge of how buffer occupancy, congestion and flow control algorithms impact performance in datacenter and WAN settings
Substantial hands-on coding skills in systems languages (e.g., C/C++, Go, Rust) and tools for network diagnostics and performance analysis
Excellent cross-disciplinary communication skills, with ability to translate theoretical insights into practical engineering deliverables and influence organizational direction
