Enterprise IT. Windows / AD / M365
The Microsoft-shop spine. A durable, hireable lane and a direct on-ramp to security, cloud and IAM.
Underrated, hireable everywhere, and the most reliable on-ramp into security, cloud and IAM from the inside of a Microsoft shop.
You want a stable, well-paid technical lane that lets you specialise later. Endpoint, Intune, AD and M365 work is everywhere and the pivot options later are excellent.
You're certain you want to write code or run product. Enterprise IT is operational work, and trying to make it into something it isn't leads to a frustrated couple of years.

- ·Pivot to IAM via SC-300
Realistic expectations
What no recruiter will tell you.
That it's a dead-end. The dead-end version is the person who learned AD in 2010 and never touched cloud or scripting. The version that pivots into cloud, security or IAM is one of the most resilient careers on this site.
Two to five years from junior sysadmin to senior is the honest range. The fast end assumes you're actively picking up PowerShell, Intune and a bit of Azure; the slow end is what happens when you stay inside a single-vendor stack and let the years do the work for you. Plateau is the default outcome, not the exception.
Where this fits
A pathway is a sequence, not a destination. Here are the roles and certs along it.
- IT Support → Sysadmin (the honest on-ramp)
The realistic first paid technology job. No shortcuts, but the cleanest gateway into every other world.
- Defensive / SOC → Detection Engineer
The realistic on-ramp into security. Defensive, structured, hireable. Biased toward SOC-stack certs. NOT CISSP.
- Network Engineer
Underrated, stable, foundational to almost every other track.
- AI will not delete IT, but it will shrink one kind of IT role
The 'AI replaces all of IT' narrative is wrong. The narrower version is mostly right, and worth planning around.
- Why most people fail trying to leave helpdesk
It's almost never a skills problem. It's a positioning problem, a portfolio problem, and a willingness-to-be-uncomfortable problem, in that order.
The next step
The pathway is plausible. Whether it holds for five years is a different question.
