And yet, OP should feel blessed. Not because of the bullshit work, but because they are one of a lucky few who have managed to land a career doing what they love. Speak to any other person that managed to do that, and they all know what OP is describing.
My only advice for OP is - work on understanding the purpose, history and alternatives of the "bullshit", then move on to work at small (5-7) independent teams where you can control the "bullshit". If you do it well, you will find your gang and it will be liberating. Read about Kelly Johnson and his teams work on the U-2 and SR71, you will love it.
