MACHO 80.7443.1718 was first identified as a heartbeat star system in the All-Sky Automated Survey for SuperNovae (ASAS-SN) with $P_{\\rm orb}=32.836\\pm0.008\\,{\\rm d}$. MACHO 80.7443.1718 is a young (${\\sim}6$~Myr), massive binary, composed of a B0 Iae supergiant with $M_1 \\simeq 35 M_\\odot$ and an O9.5V secondary with $M_2 \\simeq 16 M_\\odot$ on an eccentric ($e=0.51\\pm0.03$) orbit.
