バイトのために仕事を[習得する](https://eikaiwa.dmm.com/uknow/questions/49697/)というニュアンスの場合には、”learn”がぴったりだと思いますが、ただ単純に暗記という意味での「[覚える](https://eikaiwa.dmm.com/uknow/questions/34271/)」の場合は”memorize”を使っても良いと思います。
また、この”have to”は「～[しなければならない](https://eikaiwa.dmm.com/uknow/questions/52160/)」という義務の意味となり、自分のルールにおいて、自分で考えた上で「しなければならない」というニュアンスになります。
I have to memorize a lot for my part-time job.
※回りに言われなくても自分で義務として率先して仕事について覚えようとするニュアンスです！
part-time job で「アルバイト」を表すことができます。
相手に伝えたいニュアンスに合わせていろいろと使い分けて見てくださいね。
ご参考になれば幸いです。
