> When hiring, titles are basically ignored

As a hiring manager, this is completely accurate. I don't look at your title, I look at your scope. Tell me what you did, for whom, and what was the impact. That's all I care about.

We all know that Senior Principal Architect Engineer at 3-person startup is somewhere around junior to mid-level at a real company. Whereas some poor schmuck at a larger company with a title like "Senior Engineer I" probably owns and runs more impressive systems and works with more stakeholders than that 3-person startup will see in a year.
