No common English word has exactly the same ending /ˈstɑːfə/. Staff (/stɑːf/) shares the stressed vowel /ɑː/ and spelling 'staff'. Laugh (/lɑːf/), half (/hɑːf/) and giraffe (/dʒɪˈrɑːf/) share the same /ɑːf/ sound but not the final /ə/. Be careful with lookalikes that end in -ffer: gaffer (/ˈɡæfə/) and coffer (/ˈkɒfə/) have the same /fə/ ending as staffer, but a different vowel (/æ/ and /ɒ/), so they do not rhyme.
