。
She practices English so she can land a better job.
Literal
[topic-は] more good job [in-に] can-take-up [so-that-ように] English [object-を] is-practicing.
~ように ('so that') is a purposive marker — connects a desired outcome (here, being able to get a better job) to the action taken to achieve it. つける is the potential form of つく ('to attach to, take up [a job]') — 仕事に就く ('to take up a job') is the standard collocation, with 就く written either with this kanji or as つく in kana. The combination につける gives 'be able to take up.' もっと marks the comparative ('more, even more').
