Network engineer — tasks, one by one
The unit of analysis is the task, not the job title. Each one below carries its direction, whether the judgement rests on evidence or on platform inference, the reasoning, and what it does not establish.

Network design and capacity planning
Being augmented✓ Evidence-backedDesigning network architecture, planning capacity for growth and events, and choosing equipment and providers.
Agents now adjust capacity in operation, while design stays with engineers. Deutsche Telekom says its RAN Guardian agent reduced the time needed to manage major events from hours to around a minute. US projections expect network architect employment to grow 8 percent from 2025 to 2035, as companies investing in technologies such as AI need them to upgrade their infrastructure.
The carrier's figure is its own; the projection counts architect jobs in the US, not how much design work tools now do.
Configuration and changes
Automating✓ Evidence-backedMaking configuration changes to routers, switches, firewalls and radio networks, and managing them safely.
At the largest carriers, routine changes are made by machines. Verizon says its closed-loop automation executed over 70 million network configuration changes autonomously in 2025, work it says would have needed thousands of technicians by hand; Deutsche Telekom's agent executes measures such as adjusting configurations. When automation errs, people recover: at Cloudflare a routing change pushed through its automation leaked routes for 25 minutes until a network operator reverted it by hand. And on complex repairs language models remain unreliable: on a benchmark of 231 configuration problems, the best model fully resolved only 25% of scenarios.
The carrier figures are their own accounts, and Verizon's 'thousands of technicians' is its counterfactual, not a count of jobs; the benchmark is a preprint on synthetic networks.
Troubleshooting and outages
Being augmented✓ Evidence-backedDetecting faults, finding the root cause of outages and restoring service.
AI agents now do the first diagnosis and engineers act on it. NTT DOCOMO says its agentic system detects anomalies, identifies suspected failure points and presents recommended actions to maintenance engineers, cutting response time for complex failures by more than 50%. Agents also err when the report is wrong: on a benchmark of troubleshooting tickets, agents falsely diagnosed up to 24% of healthy networks.
The carrier's figure is its own; the benchmark tests lab networks with rewritten tickets.
Routine administration
Automating≈ Platform inferenceKeeping enterprise networks and systems patched, backed up and running day to day.
US projections expect network and computer systems administrator employment to decline 4 percent from 2025 to 2035, and give three reasons: some tasks are moving to software developers focused on DevOps, some are outsourced to companies providing networks as a service, and administrators are increasingly automating routine tasks. Only the last is automation; the first two are work moving elsewhere.
A projection for a wider US occupation that includes systems administrators; it does not separate how much of the decline each reason explains.
Outage reporting and accountability
Still human-led✓ Evidence-backedReporting major outages to regulators and answering for what happened.
US rules put a person behind the report: outage reports to the communications regulator must be submitted by a person the provider has authorised, and the final report must be attested on oath by that person as true, correct and accurate.
A US rule for communications providers; it governs how outages are reported, not how troubleshooting is done.
