We searched the 140000 highest precision TESS light curves in the southern ecliptic hemisphere. We find 27 new short-period giant exoplanet candidates which are currently being monitored for radial velocity variations with HARPS. Of these two are ideal candidates to be followed up with CHEOPS which will provide a high precision phase curve at a wavelength bluer than TESS to disentangle reflection and thermal emission. The candidates have extremely short periods of 0.88 and 0.74 days. The host stars are bright (g=11.2 and 11.5) and well-isolated from other bright sources. If successful these would be the FIRST non-transiting exoplanets discovered by phase curves from the TESS/CHEOPS missions. [truncated! Please see actual data for full text]
