  Swift J004427.3-734801 is an X-ray source in the Small Magellanic Cloud (SMC)
that was first discovered as part of the Swift S-CUBED programme in January
2020. It was not detected in any of the previous 3 years worth of observations.
The accurate positional determination from the X-ray data have permitted an
optical counterpart to be identified which has the characteristics of an
O9V-B2III star. Evidence for the presence of an IR excess and significant
I-band variability strongly suggest that this is an OBe type star. Over 17
years worth of optical monitoring by the OGLE project reveal periods of time in
which quasi-periodic optical flares occur at intervals of ~21.5d. The X-ray
data obtained from the S-CUBED project reveal a very soft spectrum, too soft to
be that from accretion on to a neutron star or black hole. It is suggested here
that this a rarely identified Be star-white dwarf binary in the SMC.
