Is this sentence grammatically correct?

"To secure a full-time, permanent position in which I can contribute my experience and skills performing manual labor, equipment operation, and roadway/highway reconstruction as a functioning member of a maintenance crew that helps Oregon communities."

works better for me, as "My objective" is not required after the colon in the title preceding it. Also position is used as a synonym for role, not as a place, so "in which" is preferable to "where", in my opinion.

Also I do wonder if stating that helping Oregon communities is superfluous.

and roadway/highway reconstruction on a maintenance crew that helps Oregon communities.

“Functioning member” should be a given and sounds awkward.

I’d put a full stop in there somewhere. Then construct another sentence from the last bit cos as it is it’s one hell of a long sentence.

No it should be like this ...

So you are denying the job, cause objective is usually you are going against the position or with holding??

Should it be only one sentence? It seems like you're putting a lot into it and like you're just cramming it all in there. Can you have more than one sentence to explain your objective?

If you are serious about helping this person find a job, PM me and I'll assist you in the application/Resume. Do not send the above objective.

I'd agree with leaving out "My objective is". Maybe you should precede "performing" with "in" or "by".

I think it's fine... though I would drop the word "functioning", which is a given...

Dont forget to add....With opportunity for advancement 😁
