Force multiplier and 10x engineer are two completely different things, at least as they are usually described. The 10x engineer is simply one who has an output far higher than average. The Principal engineer working as a force multiplier has the goal of raising the output of the entire team, group or company. If I can 1.5x a 10-person team, I'm already more valuable than that 10x engineer.
