In recent years, jet and jet substructure observables have been used at the LHC as instruments to search for new physics as well as to test perturbative and probe non-perturbative processes in QCD. Some observables are infrared and collinear (IRC) safe and thus easily comparable to first-principles calculations, while others offer direct insight into specific physical phenomena such as the quark-gluon plasma (QGP) formed in heavy-ion collisions. The high-precision capability of the ALICE tracking system allows a unique opportunity at LHC energies to measure tracks with low $p_\text{T}$, permitting both accessibility to the softer components inside jets as well as measurement of jets with altogether lower pT. This allows ALICE a rare view into QCD and QGP dynamics at pT < 100 GeV/c. We review several recent jet measurements in ALICE using both pp and Pb-Pb collisions at 5.02 TeV and discuss the results.
