As an experienced Network engineer do you know what and how AI is replacing job ? Do we need to learn AI to replace networking ? Or we need to learn AI in networking to strengthen current requirement.
Do you know the biggest risk and focus area in today's date while preparing for interview ?
I would say this:
> The biggest risk today is not AI replacing network engineers. The biggest risk is network engineers who don't learn AI, automation, cloud, and security.
The networking industry is changing faster than ever. Companies no longer want engineers who only configure routers and switches. They want engineers who can design, automate, secure, and troubleshoot hybrid environments.
What companies are hiring for in 2026
1. Network Automation (Highest Priority)
This is the number one skill.
Learn:
Python
REST APIs
Ansible
Git/GitHub
Jinja2
JSON/YAML
Terraform (basic)
Companies now expect engineers to automate repetitive tasks instead of configuring hundreds of devices manually.
Interview questions now include:
How do you automate switch configuration?
Have you worked with APIs?
Can you explain Infrastructure as Code?
---
2. AI in Networking
You don't need to become an AI engineer.
Instead learn how to use AI for:
Troubleshooting
Log analysis
Configuration generation
Documentation
RCA creation
Automation scripting
Popular AI tools:
ChatGPT
Claude
Gemini
GitHub Copilot
Companies now expect engineers to work with AI, not compete against it.
---
3. Cloud Networking

Skills that are becoming less valuable on their own
Knowing only these is no longer enough:
VLAN
STP
OSPF
EIGRP
Basic BGP
Static Routing
Basic Switching
Manual CLI configuration
These are still important fundamentals, but companies expect you to build on them with automation, cloud, and security.
---
What AI is changing
AI can already:
Generate configurations
Explain protocols
Create automation scripts
Analyze logs
Suggest troubleshooting steps
Summarize packet captures
Draft documentation
AI still struggles with:
Complex outage investigations
Architecture decisions
Customer communication
Cross-team coordination
Large-scale network design
Understanding business requirements
These remain valuable human skills.
---
Skills AI cannot easily replace
Develop:
Network architecture
Design thinking
