"Engineer " style class for DW?

Hi folks:

I'm doing prep for  a small "dw" campaign, and one of my player is a relative noob.  He's going to play a fighter, but he's new at this, is out of his comfort zone, and is more comfortable fixing cars, and general maintenance than rpgs.

So I thought, "well, if there's some kind of way to multiclass an "engineer" /fix it guy" in game i could let him have a multiclass move at level one, let my other players multiclass if they want to, and see how it goes.

Has anyone come up with "engineer" style moves i could use, or sugguestions for creating them?

thanks.

Check out the Artificer in Jacob Randolf's Alternative Playbooks (available on DriveThru RPG). Also, Johnstone Metzger's free (pay what you want?) playbooks, also on DriveThru. The Dungeoneer has some engineering moves. Oh, and the Technician from Adventures on Dungeon Planet.
