The lesson I have learned in decades of dealing with software related companies of all sizes is that you have a personality and financial problem.
That is, few companies are run by actual engineers. They are run by bean counters, lawyers, CFOs, marketing, etc. These people don't "get" programmers, engineers, etc. They don't like them, understand them, get along with them, or even have many overlapping interests. The reverse is also largely true.
For example if you go to a large financial institution you will find the C-Suite on the 28th floor with a view over the water while the IT people who build the algos that run the company are in a windowless part of some dungeon. Or if you go to a engineering company the engineers will be open plan with crap lights, chairs, desks, and dividers while the executives all have their own individual offices.
Thus, the executives start hiring people kind of like themselves to "interface" with the "weirdo" engineers. Thus was born things like the PM with a PMP, the product managers, etc.
These people are under pressure from the executive to do things one way, while the creators really should do things a different way. But this is a hierarchy. This isn't a negotiation, this isn't a system that is keen on feedback. The executives decide and the engineers are supposed to execute. They really don't like the engineers when they say things like, "That deadline is impossible. You can pick quick or you can pick good, but you don't get both." That is the sort of thing that drives an executive to a rage. They put in their quarterly plan that they were going to deliver good and cheap, how dare the engineer be so defeatist. The worst executives whine endlessly about how engineers will never give a proper answer to when something that involves lots of R&D will be done. They start droning on about boring things like all the unknowns. Again, that executive made a presentation to the board about how the next version of the product would have twice the battery life at half the cost. Is the entire engineering department conspiring to make him a liar?
Then you have internal politics. This sort of thing happens even at the level of a lemonade stand, but once you have a company with 100 or 100,000 people politics is going to rule the executive level. A critical part of office politics is to control information. Thus you get an absolute rule that the engineering types are to be kept as far away from the customer as possible. Information such as the project is going to be late is not something that almost anyone at any management or higher level wants anyone at any other management or higher level to know.
This sort of secrecy then allows grasping managers and executives to whip, threaten, make empty promises, etc to the engineers to get them to work evenings, weekends, etc all to meet some BS targets, except those targets will get various executives bonuses that are multiples of an engineer's salary, where they then magnanimously take the engineers out for a big pile of pizza or an all you can eat buffet, "on the company's dime", that might work out to $20 per engineer while that manager gets a 50k bonus that quarter alone largely because of the foolish engineers who were preached at about company loyalty and dedication.
But where this all breaks down is that you have a number of typically very very smart engineers, developers, researchers, etc, who find themselves micromanaged by people who are given a higher level of authority but who drop the responsibility on the engineers. Yet the engineers aren't allowed to communicate with the customers so they don't really know the problem, they get arbitrary deadlines handed to them. They don't get to prioritize. And worst of all the people who are typically higher up from managers tend to be morons as this is often a BS job that most people with two brain cells to rub together would reject. Sometimes the managers are former engineers but this is where the whole peter principle / fail up thing exists.
Even in huge "respected" organizations like NASA and Boeing you hear stories where engineers are saying: if you do X then Y will blow up and kill lots of people. Then some manager overrides them as they are afraid to say no to their higher ups and so on, to meet some arbitrary deadline for building something where the engineers who will build it had no input on the top down design, which is basically crap.
The pattern that I see and suspect even exists at places like NASA is that what happens is that very very smart engineers succeed despite all the terrible obstacles put in their way. Instead of good solid planning (not paperwork, but actual planning) they probably are fighting one fire after another while slipping some good engineering into the projects when the managers aren't looking.
Then just as any engineers are achieving something resembling success they get a copy of the payroll and realize the project manager who has less business experience or education than your average dishwasher but did get their PMP is paid twice what they are paid. Morale just went to zero and now your engineers come in at 9am and leave exactly at 5pm and don't answer calls on weekends anymore. Don't tell them that the CEO of the 50 person engineering firm has a travel and entertainment budget that is 3 to 6 times their annual salary, the COO has one that is 3 times, and that the CFO just got his 50k MBA paid for by the company while they can no longer expense a weekend course in town attended on their own time to get certified on a key technology the company is using in their next project.
Why this last set of disparities? The executives are where the money decisions are made and the engineering department is not.
One of the interesting bits is that what I see on a very regular basis is where those extraordinary developers, engineers, etc go: into business for themselves. They usually develop some product on their own that would have made the company millions but they do it on their own and usually without hiring any managers at all. Their old companies don't even realize what they lost, as the lying and cheating of the managers and executives will never acknowledge their mistake but will just blame the defenseless and work the remaining engineers even harder.
If I had to boil it down to a pair of lines:
Management usually hates engineering because engineers are significantly smarter and less disposable than the management themselves; thus in their insecurity they use their control of the finances to be proper bullies.
