Principal Engineer (IC5), OCI Networking – Transport Protocol Controllers & E2E Congestion Management

Description

In this role you will provide foundational expertise in transport protocols (TCP RDMA and hybrids) leading efforts to design and optimize congestion controller algorithms that deliver high throughput low latency and fairness across OCIs hyperscale environment.

Responsibilities

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 constraintsbalancing 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.

Preferred Qualifications:

• 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.

Join our team to design build and operate the advanced congestion management solutions that will shape the future of Oracles high-performance cloud network.
