As an engineer I've been able to build my ship as a straight up tank for elite STFs. When all the heals are cycling properly the ship has a pretty high resistance/heal tank which is sustainable against Tac cubes, and if/when someone else grabs aggro most of the healing can be redirected.
The ship is capable of decent sustained DPS, more so than some other tanks, but the tac skills are more for aggro sustain and debuff purposes so the escorts can burn targets down faster.
Normally I'd be running two engineering teams, but when I maxed Engineering CXP I took enough maintenance engineers to lower one to the global cool down.
The LtCom engineering skill is really open to anything, I'm using BP2 because I have Kel slotted and when 6 shuttles land on a Tac, they can do a number on it's systems.
Not bad, ditch the boarding part and grab an extends, unless you hate your teammates then keep using boarding party.
