Zusammenfassung

Proton is seeking a Network Infrastructure Engineer to own the reliability and performance of its global network. You will monitor, troubleshoot, and optimize protocol-level operations across multiple regions, and deploy robust security controls that align with privacy standards.

You will build automation in Python/Go/Rust and contribute to Kubernetes-based controllers, with involvement in upgrades and migrations. A strong Linux/DevOps foundation and firewall/ACL experience are essential.

Qualifikationen

• 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.

Aufgaben

• 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.
