Principal Network Reliability Engineer

Job Category: Product DevelopmentJob Description: Principal Network Reliability EngineerAbout the Role Oracle Cloud Infrastructure’s Network Reliability Engineering (NRE) team ensures the global OCI network – spanning thousands of routers, optical systems, and backbone links – achieves the highest levels of availability, resiliency, and automation maturity.We are seeking a Principal NRE to design and evolve OCI’s autonomous network operations platform – integrating advanced AI/ML systems, telemetry pipelines, and automation frameworks to detect, predict, and remediate issues before they impact customers.This is a hands-on technical leadership role for engineers who thrive at the intersection of network architecture, distributed systems, and applied machine intelligence.Qualifications

• Bachelor’s or Master’s in Computer Science, or a related technical discipline.
• 10+ years in large-scale network operations or reliability engineering, preferably in hyperscale cloud or carrier environments.
• Proven ability to define and improve SLIs/SLOs, MTTR, MTTD, automation coverage, and change reliability metrics to achieve 99.99%+ network availability.
• Expert-level knowledge of:
• Core protocols: IPv4/6, BGP, OSPF, IS-IS, MPLS, EVPN, VxLAN, RSVP-TE.
• Network architecture (DC spine-leaf, WAN, backbone, edge).
• Telemetry, observability, and data collection systems.
• Proven hands-on experience in automation frameworks, scripting (Python, Go, Bash), and infrastructure as code (Terraform, Ansible, or equivalent).
• Familiarity with AI/ML applications in network operations – anomaly detection, predictive analytics, clustering, or LLMs for diagnostics.
• Deep understanding of service reliability concepts (SLOs, error budgets, MTTR, MTTD, change failure rate).
• Experience with major vendor platforms: Juniper (MX, QFX, PTX), Arista, and Cisco NX-OS.
• Ability to lead cross-functional technical projects from concept through global deployment.
• Experience leading technical projects in both network and software engineering disciplines.

Preferred Experience

• Experience designing data pipelines for telemetry, flow logs, and metrics aggregation.
• Exposure to AIOps or ML-Ops frameworks (Kubeflow, SageMaker, OCI Data Science).
• Involvement in network simulation/emulation systems for failure modeling (Batfish, NS-3, Mininet).
• Demonstrated leadership in cross-domain reliability initiatives (NRE, SRE, GNOC, or Platform Ops).

Responsibilities: Architect & Operate OCI’s Global Network Fabric:

• Design, scale, and maintain production network infrastructure spanning multiple regions, with a focus on deterministic routing, high availability, and operational excellence.

Lead the AI-Driven Operations Transformation:

• Build and operationalize AI/ML pipelines for anomaly detection, predictive maintenance, and automated root cause analysis (RCA).
• Drive adoption of LLM-based diagnostic systems and event correlation engines to enhance operator efficiency and accuracy.

Automation & Orchestration:

• Develop large-scale automation frameworks using Python, Go, Terraform, and internal APIs to manage configuration drift, provisioning, and closed-loop remediation.
• Apply data-driven decision logic to trigger self-healing workflows across OCI’s networking stack.

Observability & Telemetry Engineering:

• Design data ingestion, modeling, and streaming architectures (e.g., Kafka, Prometheus, ELK, OCI Streaming) to collect and contextualize high-cardinality telemetry.
• Integrate advanced telemetry with AI systems to provide actionable intelligence and automated event triage.

Reliability Engineering Leadership:

• Serve as an SME and Tier-2+ escalation point for complex events; perform deep RCAs, create fault models, and design systemic improvements.
• Lead chaos testing, fault injection, and simulation programs to validate network resilience.
• Partner with SRE, NOC, and product engineering to define service health indicators (SLIs/SLOs) and drive toward 99.99%+ network availability.

Why Join OCI NREThis is more than a traditional network engineering role – it’s an opportunity to help shape the future of autonomous network operations at Oracle scale. You’ll drive initiatives that merge network reliability engineering, AI/ML intelligence, and self-healing automation to deliver a truly resilient global cloud platform. If you’re passionate about AI-assisted operations, predictive networking, and building systems that fix themselves, join us to lead the next era of OCI’s global infrastructure.Qualifications: Disclaimer:Certain US customer or client-facing roles may be required to comply with applicable requirements, such as immunization and occupational health mandates.Range and benefit information provided in this posting are specific to the stated locations onlyUS: Hiring Range in USD from: $86,400 to $199,500 per annum.
