The verb 'kandidieren' (to run / to be nominated) belongs to the word family of 'der Kandidat' (the male candidate) and 'die Kandidatin' (the female candidate). The ending '-ieren' is typical of many verbs that come from foreign languages, and it is always conjugated regularly.
Der amtierende Bürgermeister hat viele Kandidaten gegen sich.
The incumbent mayor has many candidates running against him.
'Kandidieren' (to run / to be nominated) is often used with the prepositions 'für' (for) and 'als' (as). You run 'für' an office (accusative) and 'als' a certain person or role (nominative).
Er kandidiert für den Posten des Schatzmeisters.
He is running for the position of treasurer.
In a political context, 'kandidieren' (to run) is often combined with 'für ein Amt' (for an office), 'für eine Partei' (for a party), or 'bei einer Wahl' (in an election). You can also run 'gegen' (against) another person.
Bei der nächsten Kommunalwahl kandidiert er für die Grünen.

In this meaning, the word is used in the context of art, culture, or science. Typical phrases are 'für einen Preis kandidieren' (to be nominated for a prize) or 'für eine Auszeichnung kandidieren' (to be nominated for an award).

'sich bewerben' and 'kandidieren' can both mean that someone wants to get a position. 'sich bewerben' is more general and fits jobs, university places, contracts, or similar opportunities. 'kandidieren' is used when someone is standing for election or is being considered for an office, a function, a prize, or membership. What matters is that with 'kandidieren', there is usually an election, nomination, or decision by others. Learners confuse the words because a candidacy can also involve a kind of application. But for a normal job, you say 'sich bewerben', not 'kandidieren'.
