There are a lot of engineers in Starfleet. Hell, the Enterprise had five or six "chief" engineers the first year it was in service! Just because Geordi was a chief engineer doesn't mean he would be assigned to work on a particular project that would have required him to leave the Enterprise to do it.
Starfleet's got a lot of ships, and a lot of chief engineers, and anyone one of 'em could have worked on the Jem'Hadar ship, because all of 'em would have been equally qualified based on experience with Dominion technology 'cause none of 'em had any!!!
