About the Team

Join a highly specialized engineering team that builds and operates large-scale network observability platforms across Telecom, on-premises, and private/public cloud 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.

As Network Observability Team Lead, you will combine people leadership with hands-on technical work. You will be accountable for the team’s delivery, development, and operational effectiveness, and shape the architecture of the telemetry pipelines and analytics platforms that turn raw network data into actionable insights. This is a player-coach role: you will lead by example through design reviews, troubleshooting, and prototyping, while giving the team the clarity, support, and autonomy to deliver.

You will report to the Head of Network Optimization, who previously led the team, ensuring leadership continuity.

Relocation to Lisbon (Portugal) is required.
