Responsibilities

• Design Huawei Cloud's hybrid optical-electrical data center network solutions, focusing on improving hyperscale distributed traffic engineering and topology engineering.
• Leverage Optical Circuit Switch (OCS/OXC) direct interconnect capabilities to implement a Dragonfly-like network topology for high-performance, low-latency data center interconnection.
• Contribute to the architecture and development of next-generation reconfigurable optical networks that support dynamic topology adjustments, adaptive routing, and optimized resource allocation under varying traffic demands.
• Collaborate on the deployment of our program network infrastructure in Ireland, tailored to local requirements.
• Publish key findings in relevant conferences and journals or apply for patents as appropriate.
• Collaborate on designing, building, and maintaining scalable network infrastructure across cloud environment.

Requirements

• 8+ years relevant network experience with a min BSc in Computer Science or related fields.
• Experience in the design and development of networking solutions based on Optical Circuit Switch (OCS/OXC).
• Experience in traffic engineering techniques—such as routing control, multi-path routing, traffic scheduling, network telemetry, and traffic modeling—to optimize network efficiency, improve resource utilization, and ensure balanced load distribution across large-scale network environments.
• Experience in designing and optimizing network topologies using techniques like Clos, Dragonfly architectures to improve scalability, fault tolerance, and performance; ability to support dynamic topology adaptation in response to real-time traffic and AI-driven application demands.
• Preferred: Solid experience in traffic engineering and topology engineering for data center reconfigurable networks based on OCS/OXC architectures.
• Experience in coding in at least two high-level programming languages such as C, C++, or Go, particularly in the context of SDN-based networking solutions development.
• Exceptional communication skills including the ability to negotiate around deeply technical topics with senior business leaders.
• Optional: Hands on experience working with AWS, Azure or GCP services.
