## About the Role

* 5+ years of hands-on experience implementing and operating enterprise-scale networks in production
 * Deep, practical knowledge of BGP, OSPF, IS-IS, EVPN VXLAN, and TCP/IP - you reason from the protocol, not the vendor UI
 * Experience configuring network security controls (firewalls, IDS/IPS, ACLs) without dependence on proprietary features
 * Able to script confidently in Python, Go, Rust, or equivalent to automate monitoring and configuration workflows
 * Solid Linux and DevOps fundamentals: comfortable at the CLI, with Terraform, and with Git-based workflows
 * Hardware-agnostic mindset - you've worked across multiple vendors and know that the protocol stack is what matters

Nice to Have

 * Experience building network telemetry pipelines using gNMIc, sFlow, BMP, or similar, integrated with Prometheus and Grafana
 * Kubernetes experience, specifically leveraging or adapting controllers
 * Contributions to open-source networking tools or internal automation frameworks
 * Involvement in NOG communities or conference speaking - we actively support community engagement

## Description

* Protocols: BGP, OSPF, IS-IS, EVPN VXLAN, TCP/IP
 * Hardware: Nokia, Juniper (hardware-agnostic, protocol-first approach)
 * Automation / Scripting: Python, Go, Rust
 * Infrastructure: Kubernetes (controllers), Terraform, Git, Linux
 * Telemetry: gNMIc, sFlow, BMP, Prometheus, Alertmanager, Grafana

What You'll Do

 * Own the reliability and performance of Proton's network infrastructure - monitor, troubleshoot, and implement protocol-level optimizations to maximize uptime across the global fleet
 * Deploy and maintain network security controls - firewalls, IDS/IPS, ACLs - without relying on vendor-specific shortcuts; ensure they meet Proton's strict privacy and security standards
 * Build and improve automation tooling in Python, Go, or Rust to reduce manual operations and expose network capabilities as self-service APIs
 * Lead or contribute to network upgrades and migrations - including DC fabric changes - with minimal disruption and strict adherence to protocol best practices
 * Operate and extend our telemetry pipelines and Kubernetes-based network controllers; contribute upstream when our work benefits the community
 * Participate in an on-call rotation, respond to high-severity incidents, and drive post-mortems through to corrective action
