The production of hadronic jets in deep-inelastic lepton-proton scattering (DIS) is sensitive both
to the strong and electroweak sectors of the Standard Model and constitutes one of the most precise
probes to study the inner structure of the proton. It further provides crucial constraints on the
flavour composition of the proton and thus in the extraction of parton distribution functions.
I will present precise QCD predictions to the jet-production process in DIS at O(as^3) both for the
neutral- and the charged-current process. These results pave the way for precision phenomenology
using jet observables at future lepton-proton colliders.
