The Topology Scaling team is responsible for deploying new capacity, new designs, establishing network connectivity for new (Oracle Cloud Infrastructure) OCI regions, and enabling compute connectivity for child sites. This includes building and managing data center fabrics, edge networks, backbone, fiber metro networks, and supporting multi-cloud initiatives.
As a Site Reliability Engineer, you will apply software engineering, systems engineering and networking practices to improve the reliability, availability, performance, and scalability of OCI’s global cloud network. You will develop automation, strengthen observability, and reduce operational toil across infrastructure connecting network devices and millions of servers worldwide.
You will own reliability throughout the infrastructure lifecycle - from architecture and deployment through production operations, upgrades, and incident response. Working with network engineering, software development, and program management teams, you will build repeatable deployment processes, improve operational readiness, and deliver resilient infrastructure at scale.
Key Responsibilities
• Design, deploy, and operate highly available global network infrastructure, incorporating resilience, fault isolation, and recovery into architecture and implementation.
• Define and monitor service-level indicators and objectives (SLIs/SLOs), using reliability metrics to prioritize improvements and guide operational decisions.
• Develop automation and tooling for provisioning, configuration management, validation, upgrades, and recovery to reduce manual work and deployment risk.
• Build monitoring, telemetry, and actionable alerting to detect service degradation and accelerate diagnosis and recovery.
• Participate in on-call rotations, lead incident response, and serve as an escalation point for complex infrastructure and connectivity issues.
• Lead blameless post-incident reviews, identify contributing factors, and drive corrective actions that prevent recurrence.
• Improve change safety through automated prechecks, staged rollouts, post-change validation, and tested rollback procedures.
• Plan capacity and evaluate performance to support growth, regional expansion, and changing workload requirements.
• Create and maintain runbooks, operational procedures, and troubleshooting guides that improve response consistency and reduce recovery time.
• Serve as a technical lead for reliability initiatives, contribute to engineering roadmaps, and mentor junior engineers.
• Partner with automation teams and vendors to resolve software defects, qualify firmware and operating system releases, and influence product improvements.
Critical Focus Areas
• Service availability, network resilience, and recovery from infrastructure failures.
• Automation of repetitive operational tasks and reduction of operational toil.
• Observability, actionable alerting, and rapid incident diagnosis.
• Troubleshooting across physical and logical network layers, including cabling, trunks, optics, routing, and connectivity.
• Root cause analysis and measurable, lasting reliability improvements.
Qualifications
• Experience operating production infrastructure in a large cloud provider, ISP, or similarly distributed environment.
• Strong troubleshooting skills across networking, Linux systems, and distributed infrastructure.
• Proficiency in Python or another programming language used to develop operational tooling and automation.
• Understanding of site reliability engineering practices, including SLIs/SLOs, error budgets, incident management, and blameless post-incident reviews.
• Hands-on experience with routing and networking technologies, including BGP, OSPF, IS-IS, TCP/IP, IPv4/IPv6, DNS, DHCP, and MPLS.
• Experience with data center network design, internet peering, inter-domain connectivity, and VPN/SSL technologies.
• Experience with configuration management, automation frameworks, APIs, and network models such as YANG, OpenConfig, and NETCONF.
• Experience using telemetry, monitoring, logging, and performance testing to assess service health and troubleshoot production issues.
• Understanding of network security principles and safe production change practices.
• Strong communication and collaboration skills, with the ability to lead incident response, explain technical tradeoffs, and influence engineering priorities.
