Job Description

- Work across protocol layers to diagnose issues at the right depth
Core Requirements
- Load balancing and traffic shaping - architecture, algorithms, health checking, failover
- NGINX and/or HAProxy - configuration, tuning, debugging in high-traffic environments
- Networking fundamentals - DNS, routing, firewall, packet capture and analysis
- OSI model fluency - comfortable working across L3–L7, TCP internals, SSL/TLS handshake and termination
- SaltStack
- Linux administration
- Python programming - automation, tooling, scripting
- Troubleshooting network and application-layer issues in production at scale
- Observability knowledge - metrics, logging, and monitoring for traffic systems
- Docker knowledge - full lifecycle and dependency management with advanced networking

- Deep understanding of the HTTP protocol - HTTP/1.1, HTTP/2, HTTP/3, WebSocket, connection lifecycle
