A slight left-field suggestion, but have you tried asking this 'competent jerk' if he wants to go for a coffee (or pint, depending on your culture)?

He might just not be aware he's being a jerk, have you tried having a casual, non-confrontational chat with him and raising your concerns?

ie "I respect you as an engineer but you can be difficult to work with sometimes"

Maybe he just isn't aware?

Sometimes you just need to communicate more and build alliances
