This includes building and managing data center fabrics, edge networks, backbone, fiber metro networks, and supporting multi-cloud initiatives.
NRB provides 24x7 operational support during build phases and oversees network and server rack adds, decommissions, and capacity expansions. The team also drives automation, process improvements, and tool development in collaboration with Network Automation to enhance efficiency.
This role involves designing, deploying, and operating large-scale global cloud networks. It requires a deep understanding of network protocols and programming skills to support automation at scale. As OCI's cloud network spans a global footprint, this role supports a vast infrastructure of network devices and millions of connected servers across dedicated backbone and internet-based connectivity.
Qualifications

• Experience in large ISP or cloud provider environments.
• Hands-on exposure to commodity Ethernet hardware (Broadcom, Mellanox).
• Deep knowledge of routing and transport protocols: BGP, OSPF, IS-IS, TCP, IPv4, IPv6, DNS, DHCP, MPLS.
• Experience with Internet peering, inter-domain networking, and VPN/SSL technologies.
• Proficiency in scripting/automation (Python preferred) and datacenter design.
• Familiarity with automation frameworks, network modeling (YANG, OpenConfig, NETCONF), and telemetry systems.
• Strong understanding of network security design, system performance testing, and operational monitoring.
• Excellent communication skills with proven ability to influence product direction and priorities.

Responsibilities
Participate in network lifecycle management through build and upgrade projects. Collaborate with program and project managers to define milestones and deliverables. Execute network changes using existing procedures and tools, and develop new procedures as needed. Serve as a technical lead on team projects, contributing to roadmap development, creating new runbooks and methods of procedure, and mentoring junior engineers.
Responsibilities include participating in solution and architecture design, developing standalone features, supporting operational rotations, providing break-fix support, serving as an escalation point, and leading post-event root cause analysis. Additional duties include coordinating with automation services to develop and integrate tooling, scripting to automate routine tasks, and acting as an SME for network automation projects. The role also involves collaborating with vendors to resolve software bugs, qualifying new firmware/operating systems, and driving product roadmap influence.
