やってくる is a compound verb meaning 'to come, to arrive, to show up' — more emphatic than plain 来る, implying she made the journey deliberately. The ~ために marks her purpose for coming. 職 (しょく, 'job, position') is slightly more formal than 仕事 and focuses on the position or role rather than the work itself.
