[vox-tech] which offer is better?

[Hai Yi]

Hello, one of my friends got two offers recently, one is related to
Linux device programming, they go like this:

Offer 1: telecommunications software developer
Responsibilities:  develop a system for monitoring all the functions
of the operations of the telephone service platform

Offer 2:linux driver developer

Which offer will provide a better career?

I think Linux offer might have a bigger job market, isn't it?

Thanks for the advice!
