About the Team
Join a highly specialized engineering team responsible for building and operating large-scale network observability platforms for Telecom, on-premises and private/public cloud 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, and operate the systems that collect, process, and analyze both network flow and telemetry data from Telecom networks running on on-premises, public and private cloud 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.
Key Responsibilities
•
Telemetry Platform Engineering: Design and maintain large-scale telemetry pipelines capable of ingesting metrics, logs, traces, and network flow data from distributed systems and telecom infrastructure.
•
Data Processing & Transformation: Develop data transformation pipelines using ETL frameworks to normalize, enrich, and model telemetry data for real-time and historical analytics.
•
Network Observability Analytics: Build advanced analytics datasets and dashboards that provide insights into network performance, failures, traffic patterns, and service health.
•
Monitoring & Alerting Systems: Implement monitoring systems and automated alerting mechanisms (use of AI/ML and prediction algorithms) to detect service degradations, network anomalies, and infrastructure failures.
•
Traffic Visibility Architecture: Design and support network traffic acquisition models using technologies such as packet brokers, TAPs, traffic mirroring, and virtual taps.
•
Observability Platform Operations: Operate and scale modern observability stacks including telemetry collectors, analytics databases, and visualization platforms.
•
Automation & Infrastructure Engineering: Automate observability infrastructure deployment and operations using Infrastructure-as-Code and container orchestration platforms.
•
Cross-Team Collaboration: Collaborate with network engineering, platform engineering, and operations teams to ensure observability solutions meet operational and analytical needs
