Tech Artist salaries vary considerably, quite a lot more than the other key roles in games dev. The other thread is spot on by exploring what defines a TA across various studios as the different ways those studios see this role is the reason for the difference in salaries.
I can give you figures for a Tools Programmer or Artist with X years experience but without a job spec I couldn’t accurately do the same for a TA. I don’t see this changing in the near future.
The demand for TAs is increasing and this is impacting on salaries to an extent. Medium to long term, Technical Artist/Animator is a good title to have and path to be walking down.
Regarding sebddd’s comment, while recruiters are more inclined to work on the higher salary roles, studios are also more reluctant to request that we find less experienced people since they can usually source those themselves. The salaries quoted through that link are on the high side but on the right lines. A Tech Art Director in London is probably earning between £45-£65k depending on studio and again, the nature of the role. A Tech Artist is anywhere from £20k up to that figure of £45k.
Part of the huge salary range is because we don’t see the same consistency with defined steps through a TA’s career in terms of titles i.e. Associate TA, Senior TA, Lead TA etc. Someone can be a TA from graduation until they take a Director role 20 years down the line and never change job title.
It goes without saying, but the way to make yourself more valuable is to emphasise the Technical in TA. Assuming you have the God given gift of artistic flair, more languages/packages = more money.
