  We present a detailed phenomenological study of polarized inclusive jet
production in electron-proton collisions at a future Electron-Ion Collider
(EIC). Our analysis is performed at next-to-leading order in perturbative QCD
using the numerical code DISTRESS and includes all relevant partonic channels
and resolved photon contributions. We elucidate the role of different kinematic
regions in probing different aspects of proton and photon structure and study
the impact of the EIC collision energy on the measurement of polarized parton
distribution functions.
