Will you proofread my cover letter?

This is for a researcher position at a nonprofit dedicated to improving social systems (per their website). The job listing can be found here. Last week, some jellies helped me with another cover letter for a different position at the same organization.

I’m basically looking to make sure that what I’ve written is understandable and informative, without being excessively wordy.

I will upload the cover letter if I get any responses. Thank you!
