What recipe are you using? Gluten development is just from working the dough (and from time) so depending on what you're doing then running it longer in the machine or adding some stretch-and-folds during the first rise for example would help. Yours does look a little under target but not disastrous. If you want a vertical-sliced fat and tall sandwich loaf without using a loaf pan you need to git gud at Shaping.
