The production of forward jets of transverse momentum $p_T(j)\approx Q$ and
large momentum fraction $x_{jet}\gg x$ probes the onset of BFKL dynamics
at HERA. A full ${\cal O}(\alpha_s^2)$ calculation of the inclusive forward
jet cross section is presented and compared to the expected BFKL
cross section. The kinematical region populated by these events and the scale
dependence of the fixed order perturbative QCD cross sections are discussed.
