I'm not even completely sure if Engineers = Space Jockey. The Space Jockey looked like it was 20 feet tall and the Engineer looked half that, at most.
I've read some fan theories out there which run with that idea. One is that the Engineers are emissaries of the Space Jockeys or something like that, and that their Space Jockeyesque suits are some form of bioengineered outfit that allows them to interface with Jockey technology.

But the size difference remains. The chair is also smaller than the one in Alien.

You can come up with whatever Fansplanations you want... the fact is- it just doesn't match and it doesn't matter to the people who made it as much as the people who watch it want it to.

You're missing the point of the theory. The theory posits that the Space Jockey in Alien would be a real Space Jockey, ie. what you see is what you get - that is the creature itself, not an external suit - while the Engineers in Prometheus are the "men in suits", the emissaries, servants, slaves, etc. of the true Space Jockies. They, being two different species, wouldn't be the same size for that very reason - they are not one and the same.

FWIW, I didn't come up with this theory and I don't really subscribe to it; I, frankly, like to take Alien on its own, and pretend none of the sequels or spinoffs - including Prometheus - ever happened. I'm just mentioning the theory for the sake of anyone interested in the possibility.
