Principal Core Infrastructure Engineer

Description

In this high-impact role you will design and build distributed systems and algorithms that measure analyze and explain network behavior across OCIs data centers and WAN. You will combine active measurements network topology routing state flow signals and switch telemetry to identify where latency congestion packet loss and failures originate.

The broader vision is to make observability an active part of the network control loop. The platform will transform trusted confidence-scored insights into signals that automated controllers can use to steer traffic mitigate congestion isolate faults and restore network health safely. These capabilities will provide the intelligence foundation for increasingly autonomous self-healing cloud networks while maintaining explainability policy controls and operational safeguards.

This position requires deep systems expertise and hands-on experience with networking algorithms telemetry and distributed computing. You will develop topology-aware observability capabilities congestion-triangulation and queue-wait reconstruction algorithms confidence-scored fault localization and production services that operate reliably at cloud scale.

• Ingest and correlate signals from active probes routing and topology systems switches ASICs queues flows logs metrics events and streaming telemetry.
• Produce ranked confidence-scored diagnoses that localize problems to the responsible path link queue device or shared network resource.
• Convert observability insights into safe explainable and controller-consumable signals for automated traffic steering congestion mitigation fault isolation and service recovery.
• Design control-loop safeguards that account for uncertainty stale or conflicting evidence policy constraints and unintended interactions between automated actions.
• Design systems that remain accurate and available despite missing or delayed telemetry topology changes clock uncertainty and partial network failures.
• Build validation frameworks that measure detection and localization time accuracy false-positive rates confidence calibration corrective-action effectiveness and resilience across complex failure scenarios.
• Apply AI-assisted software development lifecycle practices across design implementation testing debugging code review documentation and operational analysis while maintaining engineering security and quality standards.
• Write robust well-tested production code in languages such as Java Go C Rust or Python.
