This past week I spoke to a recruiter for one of the gang of 4 largest companies in tech. That term refers to Google, Amazon, Facebook, Apple (and sometimes Microsoft). The recruiter pitched me on a network engineering role - something that I've happily done for years now.
For the past 20+ years, network engineering teams from most companies have maintained the networks that connect computers which serve up every internet service we interact with each day. Network engineers make sure redundancies exist for the inevitable failures of a network that spans the globe, and they verify the health of all the hardware devices and interfaces which run the network.
A common analogy for network engineering is building the roads for the application "cars" to drive upon.
These jobs have been stable and profitable, integral to the growth and stability of any company that wants to use the internet to drive its business (read: all of them). Most would jump at the opportunity to take any job at these companies. These jobs sparkle on resumes, and even if the day-to-day is similar to most other jobs in the industry, the looming profile these companies have in the news cycle mean it'd be foolish to write off an employment opportunity like this one.
However, the world of network engineering is changing. Many would say dying.With the exception of maybe a dozen companies on the planet, nearly every company is moving away from physical data centers. IT orgs struggle with the long lead times required to make changes in physical data centers. Purchasing hardware, organizing cabling standards, cooling, 24x7 staffing, and dozens of other concerns are simply avoided by moving to the cloud.
Ironically, the only companies who aren't decreasing their data center footprint? Cloud providers.Because of the increased demand, cloud providers are growing their physical data centers at an incredible rate. This requires hiring network engineers, data center engineers, and others with the skillsets to grow them in a scalable way.
|The gilded cage of skill-set lock-in|
Only cloud providers still invest in physical data centers - and the skillsets required to run them.Spending time in your career at one of these companies in a department focused on these legacy networks is a dead-end in a career because of this skillset lock-in. It'll be difficult for the folks locked into these positions to leave the very small network of a dozen or so companies that provide these massive clouds and take just a job at just about anywhere else, because these other companies are looking for reliability engineers (SREs), DevOps engineers, and any number of other software-defined cloud computing experts that need entirely different skillsets than those harbored within these divisions at the gang of 4.
If you have the opportunity to work in these divisions at cloud providers, good luck to you! Their famously great pay and benefits are nothing to scoff at. But I hope you consider my points above about career lock-in. Your career must be played as a strategic long-game, and I worry these jobs might be the wrong move.
Best of luck out there.
