I have a scanner connected to my machine which works well, but the resulting PDF files are often slightly tilted. Is there a program out there that can deskew the PDF pages? I know Adobe Acrobat does this, but I'm not running that on my Arch machine.

How are you creating the PDF?
As far as I know, ocrmypdf, gscan2pdf and sane-scan-pdf should support deskew. There is also the gimp plugin deskew.

I'm using gscan2pdf, and it often fails to deskew. That's why I'm looking for an alternative solution.

You could scan as images or extract the images from the PDF, then deskew them with e.g. unpaper (I think gscan2pdf uses that as well), gimp+deskew plugin or deskew and then recreate a pdf afterwards.
Edit: If the deskew binary works better, maybe you can set a user defined command to run it on scanned images in gscan2pdf.

Masterpdfeditor in the AUR has a transformation matrix function that can skew - I have not tried it on a scanned image.
