That's embedded development in a nutshell. The only part you're missing is wasting a week of your life tracking down a compiler heisenbug, because embedded devices have niche, poorly maintained compilers.
Though to be honest it's a matter of taste; natural sadists tend to "enjoy" embedded.
Or spending three weeks trying to achieve timing closure on a design, only to finally realize after much inspection of the routed designs by myself and an IntelFPGA FAE that the router was smoking digital crack the whole time and had no clue how to route their own divider units?
Or maybe the programming facility reversed bit ordering on a batch of the FPGA's flash chips and you only learn of that after a very, very long couple of nights of language barrier back and forth with a flummoxed customer.
The joys are endless.
