The more difficult the tools he knows (and in the case of Matlab, you actually need to know math to make real use of it), the less competition there is. For C/C++, at the very least he can look into Embedded Systems, where you do need to know C/C++.
also, if he is actually proficient at a hardcore language like C, learning some of the more in-demand languages shouldn't be a problem. i guess if he doesn't have any web development experience, that could potentially limit his options a bit, but i don't think it would be a deal breaker, depending on how much wiggle room there is for ramping up post-hire.

Since he knows C / C++ / Matlab, he should be able to find a job.
Why do you think that's the case?
