What is the alternative word to "conservative"?

I was reading one of my old posts and I came across the following sentence:

During my career as a web developer, I encountered many conservative developers.

Is it valid to say: "conservative developer" in English?

I mean the developer who's afraid of sudden or great changes. If not, what is the alternative term then?

Solution 1:

Traditionalist

A traditionalist is a person who supports the established customs and beliefs of his or her society or group, and does not want to change them.

— Collins English Dictionary

You could say "conservative", but it may wrongly imply a political association.

Another option: orthodox

Orthodox—following or conforming to the traditional or generally accepted rules or beliefs of a religion, philosophy, or practice.
