Anyone ever use Structural Equation Modeling in their work?

I've got a year left in my PhD (a quant social science), but plan on going into DS after. My department is offering a 2nd advanced SEM course, but I'm not sure if it's worth taking it in my final year since I'll be dissertating and doing some part-time DS work.

Do DS folks ever use SEM? How can I find those DS jobs?
