Eight years of relevant network engineering experience; or a bachelor’s degree in a relevant technical field and four years of experience; or a master’s degree and two years of experience; or a relevant doctorate.
Strong understanding of Layer 2 through Layer 4 networking, IP addressing and subnetting, BGP, OSPF, IPv4, IPv6, TCP/IP, DNS, DHCP, NAT, ECMP, and high-availability design.
Experience designing, deploying, or operating data-center, cloud, service-provider, or large-enterprise networks.
Hands-on experience automating network provisioning, configuration, validation, or operations using Python or another programming language.
Experience with Git, APIs, CI/CD workflows, automated testing, configuration modeling, or infrastructure-as-code practices.
Experience executing production network changes with appropriate risk assessment, validation, rollback, and change-management controls.
Demonstrated troubleshooting skills across network protocols, devices, automation systems, and physical infrastructure.
Experience participating in incident response, root-cause analysis, operational readiness, and continuous improvement.
Ability to work independently, manage project milestones and dependencies, and coordinate effectively with engineering and operations teams.
Strong written and verbal communication skills, including the ability to produce clear technical designs, runbooks, and project updates.

Experience with commodity Ethernet platforms, optics, structured cabling, hardware qualification, and network operating-system validation.
Experience improving operational workflows through automated validation, reusable runbooks, deployment guardrails, or configuration-drift detection.
Experience using AI-assisted engineering tools to improve automation, testing, troubleshooting, documentation, or operational efficiency.

Responsibilities

Design and operate data-center fabrics, routing, and secure connectivity supporting OCI’s physical network infrastructure.
Translate customer and product requirements into network designs, configuration standards, and deployment plans.
Own projects from technical design through validation, deployment, documentation, and operational handoff.
Build network automation and validation tools using Python, APIs, Git workflows, and infrastructure-as-code practices.
Execute production changes with pre-change checks, post-change verification, and rollback procedures.
Improve monitoring, capacity planning, runbooks, and incident response; troubleshoot issues across protocols, devices, optics, and automation.
Participate in a periodic on-call rotation, respond to large-scale network incidents, and drive them to resolution.
Contribute to design reviews, develop repeatable standards, and mentor other engineers.
