I work in avionics and the principles are exactly the same. And I think it applies to all somewhat critical embedded systems.
There are some details that may change, for example, we use mostly C, specialized software and a bit of ADA, no C++ in embedded systems. But the input-output periodic loops, isolation and making sure things continue working in degraded condition principles are the same.
Nothing special about SpaceX here, for good reasons. In fact, some of it might be mandatory if you want to fly something that can cause serious damage if you it fails, be it a rocket or a plane.
