Senior Network Developer [NAT]

Description

As a Senior Network Development Engineer, you will provide the technical engineering expertise behind that delivery. You will work across the lifecycle of circuits, fiber, wavelengths, Internet connectivity, backbone infrastructure, and data center interconnects. You will partner closely with Program Managers, OCI network engineering teams, and external network providers to translate network requirements into deployable solutions, validate that delivered infrastructure meets those requirements, troubleshoot complex issues, and drive connectivity through production readiness.

This role combines strong network engineering fundamentals with hands-on infrastructure delivery, troubleshooting, supplier engagement, and continuous improvement.

Responsibilities

What You'll Do

• Provide technical leadership for the delivery and activation of network connectivity supporting OCI regions, AI infrastructure, capacity expansion, and strategic network deployments.

• Translate network designs and engineering requirements into technical requirements for carriers, fiber providers, ISPs, colocation providers, and other infrastructure partners.

• Support the delivery of carrier circuits, dark fiber, lit fiber, wavelengths, optical transport, Internet transit, peering, backbone connectivity, cross-connects, and data center interconnects.

• Review connectivity requirements, designs, demarcation points, handoffs, physical paths, optics, interfaces, capacity, and technical dependencies before implementation.

• Validate delivered infrastructure against OCI engineering requirements before operational handoff.

• Troubleshoot Layer 1 through Layer 3 connectivity issues across fiber, optics, transport, Ethernet, routing, and provider networks.

• Perform or support circuit acceptance, fiber validation, optical testing, turn-up, activation, and remediation.

• Diagnose complex connectivity issues and coordinate technical resolution across OCI engineering teams, data center teams, and external providers.

• Serve as a technical escalation point for supplier delivery and activation issues.

• Perform root cause analysis and drive corrective actions for recurring technical and delivery failures.

• Partner with Program Managers to identify technical risks, dependencies, blockers, and recovery options.

• Develop and improve technical standards, Methods of Procedure, runbooks, acceptance criteria, and operational documentation.

• Participate in architecture and design reviews and provide feedback based on delivery and operational experience.

• Work with suppliers and internal engineering teams to improve installation quality, acceptance testing, troubleshooting, and activation readiness.

• Use existing automation and develop scripts where appropriate to simplify repetitive engineering, validation, data analysis, and troubleshooting tasks.

• Use AI-assisted engineering tools to accelerate troubleshooting, analysis, documentation, scripting, and operational workflows while applying sound engineering judgment and validating outputs.

• Mentor junior engineers and contribute to raising technical standards across NAT.
