'Wirken' does not mean 'to work' in the sense of having a job. If you want to say 'I work at a bank,' you have to say 'Ich arbeite bei einer Bank.' 'Wirken' describes an effect or a creative activity.

to work
'arbeiten' and 'wirken' can both describe someone or something being active or having an effect. 'arbeiten' is used very often for work, activity, or technical processes. 'wirken' is used when something has an effect on someone or something, for example a medicine. In addition, in elevated language, 'wirken' can mean that someone is active in a particular field. The words can be confusing because both can be connected with activity. In everyday language, 'arbeiten' is usually more natural for people and tasks. 'wirken' fits better when the effect is the main focus.
