As a hack on this, when negotiating to join a company, you generally want to be at {highest title} + {lowest on pay band for that title}.

Sometimes specific title requirements preclude this (e.g. "We don't give new people X title immediately"), but it's a good rule of thumb.

It makes yearly pay bumps much easier for your manager to justify ("So-and-so is well within salary ranges for their title"), versus them having to fight for an exception to policy.
