In my experience, job titles and capabilities rarely goes hand in hand. Seniority (junior, senior, principal) is sometimes projected to titles (web dev, developer, engineer) making it all the more confusing. Where I come from, certain braches of industry have simply made it illigal. For example, a nurse cannot call themselves doctors. It pertains to most knowledge-based branches of industry here, except for software development.
