As a commenter already pointed out, "with you" is superfluous here. Neither adding nor removing it affects the correctness of the sentence, but if you ask me as a native American English speaker it sounds better without it.
More to the point, though, the sentence feels off in different ways. "About" is just as superfluous as "with you," and "further" feels a bit presumptuous--assuming this is a cover letter, you haven't yet discussed anything with anyone, even if it is your hope to discuss these issues with someone at the company. Finally, at least in American English, there's been a strong trend toward using contractions always, even in formal language. "I am" feels a bit quaint, in my opinion.
Might you consider, instead, something like this? "I'm keen to learn more about how I can help contribute to your company." If it's American English, replace "keen" with "eager."
