Side by side
Field / Infrastructure Engineer vs Network Administrator
These two share 81% of the same working profile. Enough in common to be worth comparing, and enough apart that the choice matters.
This pairing exists because the move is a real one: moving from the physical layer to the logical one.
The short answer
Not which is better — they pay similarly often enough that the question is meaningless. This is what each one asks of you more than the other does.
Where they actually differ
The same 41 dimensions the assessment scores you on, applied to the roles themselves. Bars show each role's emphasis relative to its own strongest trait — so this is about shape, not size.
A short bar means the trait is not part of what defines that role — not that it never comes up. Every job in IT involves some troubleshooting; only some are built around it.
Watching for the thing that is about to go wrong.
Making something new exist that did not exist yesterday.
Cables, racks, radios, and the equipment you can touch.
How information moves between machines, sites, and users.
Routes, addresses, packets, and paths.
Narrowing down a broken thing until the cause is cornered.
A defined thing to implement, with an end date.
What they have in common
Worth knowing for two reasons: it explains why you are torn, and it is the part that transfers if you start with one and move to the other later.
Keeping live systems healthy, and people unblocked, right now.
What you actually do all day
Field / Infrastructure Engineer
Do the work that only happens with your hands on the actual equipment.
- Install, terminate and test cabling, then label it properly
- Rack, cable and commission switches, radios and appliances
- Diagnose faults that could be physical, optical or configuration
- Carry out site surveys and document what is actually there
- Respond to outages that need someone physically present
Network Administrator
Keep an existing network healthy, and be the person who fixes it when it is not.
- Work the overnight alerts and decide what actually needs attention
- Trace "the internet is slow in Building C" down to a single switch port
- Add VLANs, update firewall rules and reconfigure ports as teams move around
- Manage IP addressing, DHCP scopes and DNS records
- Replace failed hardware and coordinate vendor RMAs
Getting in, and what it pays
The honest downside of each
Often the deciding factor. Both of these are good jobs for the right person; the question is which cost you would rather live with.
Technologies
The shared column is the practical reason these two are one career move apart rather than a restart — that part you would take with you.
Feel the difference before you commit to it
Reading two columns will not settle this. Doing an hour of each probably will — both are free and run on the machine you already have.

Take a vague, badly-described complaint from a real human being and turn it into something you can actually diagnose — then fix it and write it down.

Follow a packet →
Find out where your own traffic actually goes on its way out of the building — and what it looks like when it stops arriving.
Certifications
Last, as everywhere on this site. If both paths share an early certification, that is the one to start with — it keeps the decision open while you find out which you prefer.
