Is this correct and natural?

Gary has worked ten years as an event coordinator. His abilities and skills lend themselves well to this job, which requires someone to be precise and well-organized.

It sounds better than your previous sentence with "lend itself" and yes, it's possible here. For some reason I still feel the phrase doesn't lend itself well to this context but I wouldn't say it's wrong.

which requires someone to be precise and well-organized.

Who's that someone?

You mean "which requires someone WHO IS precise and well-organized".

I assume you want to praise him. Try:

Gary has been an event coordinator for the past ten years. He is very good at it. In fact, he is booked solid for the next twelve months.

I realize that you want to use the phrase "his abilities and skills lend themselves well to this job", however it seems unnecessary in this context. (Success speaks for itself.)
