If this is a useful piece of information about the job offer then " tip " could be helpful: Thank you for the tip.
Instead of the word " information " you can say " info " which will sound less formal.
Thanks for the info.
If it's a reference to a webpage or maybe some other source then the word " link " will be the right one.

I wouldn't say that the word information sounds formal.
Though, I agree with you that it is, in some sense, broad in meaning.
It's nevertheless a very basic and everyday word just like many other words in English.
So, there's really nothing wrong in using it the way you're using it in your sentence.
But if you do insist on sounding a little bit more terse and casual, consider substituting the whole thing with find : Thank you for your find .
Thanks for the find .
Possibly, a word like tidbit would work even better: Thanks for the tidbit .

As Cookie Monster mentions, Thank you for your find works well.
Also: Thank you for the listing.
Thank you for the lead.

You may want to thank him for contacting you rather than for the information -- that is, the communication is more important than the data.
So you can choose from many synonyms for the communication itself and the act of communicating: contact, notice, notification, note, message, email, reaching out, letting me know, telling me, and so on.
For example: Thank you for letting me know about the job.
or Thank you for your message about the job
