Senior Network Engineer - W2 Only

1. Deep Understanding of Network Infrastructure
This refers to a comprehensive grasp of how networks are physically and logically structured. It includes:

Hardware knowledge: Routers, switches, firewalls, load balancers.
Topology design: Understanding of LAN, WAN, and data center layouts.
Performance optimization: Ability to identify and resolve bottlenecks or inefficiencies.
Security integration: Ensuring infrastructure is secure from threats while maintaining performance.
Why it matters: This role supports both operational and project-based work, so a solid foundation in infrastructure ensures the engineer can troubleshoot, maintain, and scale the network effectively.

2. Network Design
This skill involves planning and architecting networks that are scalable, secure, and efficient. It includes:

Designing IP schemas: Efficient use of IP address space and subnetting.
Redundancy and failover planning: Ensuring high availability.
Protocol selection and configuration: Choosing the right routing and switching protocols.
Documentation: Creating detailed network diagrams and documentation for future reference.
Why it matters: The engineer will eventually work on the ICSR project, which likely involves complex industrial control systems. Strong design skills are essential for building robust solutions.

3. Proficiency in BGP (Border Gateway Protocol)
BGP is a core routing protocol used to exchange routing information between autonomous systems on the internet and large enterprise networks. Key aspects include:

Route advertisement and filtering: Controlling which routes are shared and accepted.
Path selection: Understanding how BGP chooses the best path.
Troubleshooting: Diagnosing issues like route flapping or misconfigurations.
Security: Implementing route validation and prefix filtering to prevent hijacking.
Why it matters: BGP is critical in large-scale networks like ExxonMobil s, especially when dealing with multiple sites or external connectivity. Mastery of BGP ensures stability and control over routing behavior.
