As for me, from this, at this company, new my job begin. [Syntax]

The correct answer is "しごとを". "しごと" (job) is the direct object of the verb "はじめます" (to start), and "を" is the particle that marks direct objects. The preceding words "あたらしい" (new), "わたし" (my), and "の" (possessive particle) all describe and modify this "しごと," clarifying what kind of job is being started and whose it is. "しごとを" correctly identifies the thing being started.

正解は「しごとを」です。「しごと」は動詞「始めます」の目的語（もくてきご）で、「を」は目的語を示す助詞（じょし）です。前の言葉（ことば）が「しごと」を説明（せつめい）しています。
