About the Team

Join a highly specialized engineering team responsible for building andoperatinglarge-scale network observability platforms for Telecom, on-premisesandprivate/publiccloud infrastructure environments.

Our mission is to provide deep visibility into network performance, service quality, and operational health across distributed systems. We ingest and analyze massive telemetry streams, network traffic metadata, and service events to power real-time analytics, automated alerting, and operational dashboards used by engineering and operations teams worldwide.

You will work at the intersection of mobile network engineering, data engineering, and platform observability, designing scalable telemetry pipelines and analytics platforms that transform raw network data into actionable insights.

About the Role

As a Mobile Networks Observability Engineer , you will design, build, andoperatethe systems that collect, process, and analyzeboth network flow and telemetrydatafromTelecomnetworksrunning onon-premises, public and privatecloud infrastructure.

You will work with modern observability platforms, telemetry pipelines, and high-performance analytics databases to provide deep visibility into network behavior and service quality.
