Senior Network Developer

Oracle•Reston, VA

9d•$91,400 - $187,000

About The Position

As a Senior Network Development Engineer on the NAT team, you will provide technical expertise to deliver, validate, and activate OCI network connectivity. The work spans circuits, dark fiber, optical wavelengths, Internet connectivity, backbone infrastructure, and data center interconnects, from technical readiness and provider delivery through acceptance testing, production turn-up, and operational handoff. You will partner with Program Managers, OCI network engineering and operations teams, data center teams, and external network providers to turn network requirements into deployable solutions. The role includes validating circuit designs and delivery documentation; confirming cross-connect, cabling, and interface readiness; coordinating provisioning and activation; performing and reviewing acceptance tests; and troubleshooting physical, optical, and network-layer issues. You will verify that connectivity meets capacity, performance, reliability, and resiliency requirements, document deficiencies, and drive technical issues to resolution. You will establish readiness and acceptance criteria, maintain circuit records and test evidence, support controlled production changes, and ensure operational teams receive the documentation needed to support delivered infrastructure. The role combines network engineering fundamentals with hands-on delivery, complex troubleshooting, supplier accountability, and continuous improvement of testing, automation, and delivery processes.

Requirements

Experience working in a hyperscale cloud, ISP, telecommunications provider, data center, or large-scale enterprise networking environment.
Strong understanding of Layer 1, Layer 2, and Layer 3 networking.
Deep knowledge of at least two networking protocols or technologies, including BGP, OSPF, IS-IS, MPLS, TCP/IP, Ethernet, optical networking, Internet, or backbone networking.
Experience operating or supporting large-scale network environments.
Hands-on experience troubleshooting network connectivity across physical infrastructure, optics, Ethernet, routing, and provider networks.
Understanding of fiber infrastructure, structured cabling, cross-connects, optical transceivers, and physical network troubleshooting.
Experience with Internet connectivity, peering, backbone networking, or service provider networks.
Ability to read and understand network diagrams, engineering designs, technical requirements, and implementation documentation.
Experience working across technical teams to identify root cause and drive complex network issues to resolution.
Strong written and verbal communication skills.
Ability to operate independently on defined technical objectives while coordinating effectively with Program Managers, engineering teams, operations teams, and suppliers.
Experience with scripting or programming, preferably Python, or another scripting or compiled language.
Understanding of network automation concepts and ability to leverage existing automation and tooling in day-to-day engineering workflows.

Responsibilities

Provide technical leadership for delivering and activating network connectivity for 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 delivery of carrier circuits, dark and 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, applying engineering judgment and validating outputs.
Mentor junior engineers and contribute to raising technical standards across NAT.
