Do Network Engineers need to know coding?

Jonathan

Do network engineers really need coding skills in today’s IT world, or is traditional networking knowledge still enough? How does scripting and automation improve network management and scalability, why are tools like Python and infrastructure-as-code becoming more relevant, and who benefits most when network professionals combine networking expertise with programming skills?

In the current era of technology, I believe that knowing how to code is no longer optional for network engineers. We have moved far beyond the days when you could manage a network by logging into one switch at a time. Today, when you are responsible for thousands of devices across multiple data centers, manual configuration is physically impossible. I see coding, specifically Python, as the "new CLI" that allows us to manage infrastructure at a massive scale. This perspective suggests that if you cannot automate, you cannot compete. Transitioning to a model where you write a script to deploy a VLAN across five hundred switches saves an incredible amount of time. I feel that coding allows us to act like architects rather than manual laborers. Using active voice, we can say that automation "multiplies" the impact of a single engineer. It is the only way to keep up with the speed of modern business requirements while ensuring that the network remains consistent and reliable across the entire global enterprise.

I strongly believe that the future of networking is "NetDevOps," which means we must adopt the same tools and workflows as software developers. This includes using version control like Git, writing automated tests, and building CI/CD pipelines for our network changes. I see coding as the "common language" that finally allows network engineers and developers to work together. This perspective highlights that we should treat our network configuration just like application code. Transitioning to this mindset prevents "configuration drift" and makes the network much more predictable. I believe that by learning to code, we can move away from "snowflake" configurations that are documented only in someone's head. I feel that this rigor brings a new level of professionalism to the field. It allows us to roll back changes instantly if something goes wrong, just like a developer reverts a buggy code push. Coding isn't about becoming a full-time programmer; it is about using the best tools available to build a more robust and agile infrastructure.

While everyone is talking about automation, I still believe that a deep understanding of networking protocols like BGP, OSPF, and Spanning Tree is more important than knowing how to code. You can be the best Python programmer in the world, but if you don't understand how a packet travels through a router, you will never be a great network engineer. I see coding as a "nice-to-have" skill that sits on top of a solid foundation of technical knowledge. This perspective warns against becoming a "script kiddie" who automates things they don't fully understand. Transitioning too quickly to automation without mastering the fundamentals can lead to massive, automated disasters. I feel that the Command Line Interface (CLI) is still the best place to learn how a device actually thinks. I believe that while scripts can help with repetitive tasks, the "human in the loop" will always be needed for complex troubleshooting and design. You should focus on being a great engineer first and a coder second, ensuring your foundation is rock-solid.

From a business standpoint, I believe coding is necessary because it is the only way to eliminate "toil." Toil refers to those manual, repetitive tasks that are boring for humans and prone to errors. I see coding as the ultimate tool for increasing operational efficiency. This perspective focuses on the fact that a single typo in a manual configuration can take down an entire company's network. By using scripts, we ensure that every change is executed perfectly and consistently every single time. I feel that this reduction in human error is the biggest benefit of the "coding for engineers" movement. Transitioning to an automated workflow allows a small team to do the work of a much larger one. I strongly believe that by removing the "grunt work" from the job, engineers can focus on more interesting and strategic projects. It makes the work day more engaging and less stressful. Coding turns the "maintenance" of a network into the "evolution" of a system, providing much more value to the organization.

If you are working in the cloud, I believe coding is an absolute requirement. In environments like AWS, Azure, or Google Cloud, there is no physical console to plug into. Everything is virtualized and controlled through APIs. I see "Infrastructure as Code" (IaC) tools like Terraform and CloudFormation as the primary way we build networks today. This perspective argues that the traditional "hardware-only" engineer is becoming obsolete in a cloud-native world. Transitioning your skills to the cloud means learning how to define your VPCs, subnets, and gateways in a text file. I feel that this is a much more powerful way to work. You can "template" an entire network and deploy it to a new region in minutes. I strongly believe that without coding skills, you are locked out of the most exciting and high-paying jobs in the industry. The cloud has turned networking into a software problem, and you need software skills to solve it. It is a fundamental shift in the very nature of what a network is.

I believe the rise of Software-Defined Networking (SDN) has made coding a mandatory skill. In an SDN environment, the "control plane" is separated from the hardware and managed by a centralized software controller. I see this as the most significant change in networking history. This perspective highlights that we now interact with the network through an "intent-based" interface rather than individual box configurations. Transitioning to SDN requires you to understand how to interact with these controllers using APIs and scripts. I feel that this makes the network much more "intelligent" and responsive to the needs of the business. I believe that by using code, we can create networks that automatically adapt to traffic patterns or security threats. Using active voice, we can say that SDN "abstracts" the complexity of the hardware, but it requires the engineer to be comfortable with the software layer. Coding is the key that unlocks the true potential of these advanced systems, allowing for a level of flexibility and automation that was previously impossible.

From a customer’s point of view, the production support team is the "face" of the company when things go wrong. I believe that the user experience doesn't end when a person buys a product; it continues throughout the entire time they are using it. This perspective sees production support as the final, and perhaps most important, stage of the user journey. Transitioning from a state of "broken service" to "restored service" is a moment of truth for the customer relationship. I strongly feel that a positive support experience can actually build more loyalty than a service that never broke at all. By providing fast, empathetic, and effective solutions, the support team demonstrates that the business truly cares about its users. Using active voice, we can say that production support "humanizes" the technology. It bridges the gap between a cold, digital interface and a real person who can solve a problem. In a world where many services are identical, the quality of your support can be the only thing that truly differentiates your business from the competition.

I believe there is a "middle ground" for network engineers who are intimidated by full-blown programming. You don't necessarily need to be a Python expert to benefit from automation. I see tools like Ansible, Terraform, and YAML as "low-code" solutions that allow you to automate without writing complex logic. This perspective focuses on the "declarative" approach, where you simply describe what you want the network to look like, and the tool makes it happen. Transitioning to these tools is a great first step for any traditional engineer. I feel that this makes automation much more accessible to everyone. You can start by using pre-built "playbooks" to handle simple tasks like backing up configurations or updating passwords. I believe that as you get more comfortable, you will naturally start to write your own more complex scripts. You don't have to become a software engineer overnight; you just need to start using the tools that make your life easier. It is a journey of continuous learning that starts with a single automated task.

From my perspective, coding is a vital skill for modern network security. We are no longer just building walls; we are building "automated defenses." I see coding as the way we implement "Zero Trust" and real-time threat detection at the network level. This perspective highlights that when a security breach happens, every second counts. By using code, we can create automated responses that "quarantine" an infected device or block a malicious IP address across the entire global network in milliseconds. I feel that this is much more effective than a human trying to manually update firewall rules during an attack. Transitioning to a code-based security model allows us to perform constant, automated audits of our network to ensure we are always in compliance. I strongly believe that the intersection of networking, security, and code is one of the most important areas in tech. By learning to script, you aren't just a builder; you are a defender. It gives you the power to protect your organization's data with a level of speed and precision that is only possible through automation.

The most practical solution, in my opinion, is that network engineers should be "code-literate" rather than skilled developers. You must be able to read a JSON file and use an API, but you do not need to know how to develop a mobile application. This is a "hybrid" role, in my opinion, where you use code as a tool to improve your performance. According to this viewpoint, you should concentrate on "functional" coding—creating scripts that address particular, practical networking issues. You become a far more proficient troubleshooter when you adopt this hybrid mindset. You can find a needle in a haystack in a matter of seconds by writing a script to "scrape" data from one hundred routers. This seems to be the "sweet spot" for the majority of engineers. It blends the effectiveness of contemporary software tools with the in-depth technical understanding of networking. If you are prepared to learn the fundamentals of automation, I think your work will become more engaging, significant, and in line with the current trends in the technology sector.
