There can be 'levels' that is semi-independent from 'job title'. As this is commonly the case in many companies. Many companies have multiple levels for a given job title. Everywhere I've worked in software has had 'levels' with a finite range, and as you reach the upper bound of the range, you move to the next 'level'. There is some overlap in the level's ranges. Also as I originally stated, this is the 'minimum' for simply a starting talking point, it will still allow some to be hidden/obscured. There is always 'additional bonuses/awards' on per project basis. e.g. Project ___ grants an additional $$$ either 1 time bonus on start, on complete, or recurring. If someone's value production is greater, than they should be promoted to the next 'level' which comes with increased compensation.
