On-siteGeneva, Illinois, United States
Job Summary
Own the reliability and performance of Proton's global network infrastructure by monitoring, troubleshooting, and implementing protocol-level optimizations to maximize uptime. Deploy and maintain network security controls including firewalls, IDS/IPS, and ACLs to meet strict privacy standards, while building automation tooling in Python, Go, or Rust to expose network capabilities as self-service APIs. Lead network upgrades and migrations with minimal disruption, operate telemetry pipelines using gNMIc and sFlow, and respond to high-severity incidents during on-call rotation. Drive post-mortems to corrective action and contribute upstream to community tooling. Requires 5+ years of enterprise-scale network experience with deep knowledge of BGP, OSPF, IS-IS, and EVPN VXLAN.
