Cracking the code for job title/description

In three yearsish I plan to change jobs from having the same family work place for 11 years currently. I'm starting to search to see what is out there I feel very confused about job descriptions and titles. I know both sides provide a lot of fluff to the job hiring process, but is there a way I can find simpler description?

Everything is labeled as senior position (from reading it likely isn't) and nothing is really to the point (whole page of text to maybe say we need someone to work in hr).
