Revolution at the heart of the network: From rack cabinets to code
Just a decade ago, the work of a telecommunications engineer was mainly associated with configuring dedicated hardware devices from providers such as Ericsson, Nokia, or Huawei. The year 2026 definitively closes this era. Today's 5G networks (and soon 6G) are no longer built on proprietary hardware, but on standard x86 servers running private telco clouds (Telco Cloud).
At the center of this transformation is NFV (Network Functions Virtualization) – a technology that moves network functions from physical boxes to virtual and containerized environments. It is the experts capable of managing this layer who are currently "worth their weight in gold" in ITcompare rankings.
Why NFV became the foundation of a modern operator?
In 2026, telecommunications operators are no longer fighting just for coverage, but for flexibility and the speed of deploying new services. Network functions virtualization allows for:
- On-demand scalability: Increasing network capacity in response to a sudden surge in traffic (e.g., during sporting events) is done by launching additional instances of virtual machines or containers, rather than physical infrastructure expansion.
- Cost reduction (CAPEX/OPEX): Using standard servers instead of dedicated hardware significantly lowers entry and maintenance costs.
- Network Slicing: A key 5G feature that allows for the creation of network "slices" with guaranteed parameters for specific clients (e.g., for autonomous vehicles or the medical sector) is impossible to implement without an advanced NFV stack.
Telco Cloud Engineer Profile 2026 – sought-after competencies
Currently, we are witnessing the birth of the "hybrid engineer" in the labor market. Operators are no longer looking for classic network administrators, but specialists who combine knowledge from two worlds: classic Telco and modern Cloud Computing.
Key technologies in the portfolio:
- Orchestration (MANO): Knowledge of ETSI MANO standards and tools such as ONAP (Open Network Automation Platform) or OSM (OpenSource MANO).
- Cloud environments: Proficiency in OpenStack (IaaS layer) and increasingly Kubernetes (CaaS layer for Cloud-native Network Functions – CNFs).
- Automation and IaC: Knowledge of Ansible, Terraform, and CI/CD processes is essential for managing hundreds of virtual network functions.
- Network Virtualization (SDN): Understanding how virtual switches (OVS) and technologies such as SR-IOV or DPDK work, which ensure high data throughput performance in the cloud.
Job market: Where to look for offers and what earnings to expect?
The demand for Telco Cloud engineers in 2026 comes not only from the big four mobile operators. Specialists are also sought by cloud service providers (Hyperscalers) building dedicated edge solutions (Edge Computing) and companies from the Industry 4.0 sector implementing private 5G networks.
Data from the ITcompare aggregator indicates that an NFV/Telco Cloud Engineer can expect a salary 20-30% higher than a standard Linux systems administrator with similar experience. This results from the uniqueness of the competencies – one must not only understand the cloud but also the specifics of telecommunications protocols and rigorous requirements regarding low latency.
How to start a career in Telco Cloud?
For individuals from the IT sector, the natural path is certification in the area of Cloud Native (CKA/CKAD) and exploring the specifics of OpenStack. For telecommunications engineers, the key will be moving away from vendor-specific CLI configurations towards learning programming (Python) and automation tools.
The future of telecommunications is written in code. If you want to build the networks of tomorrow, NFV virtualization is a competency that in 2026 will open doors for you to the most innovative projects on the market.
