We investigate the effects of dissipation and driving on topological order insuperconducting nanowires. Rather than studying the non-equilibrium steadystate, we propose a method to classify and detect dynamical signatures oftopological order in open quantum systems. Bulk winding numbers for theLindblad generator $\hat{\mathcal{L}}$ of the dissipative Kitaev chain arefound to be linked to the presence of Majorana edge master modes -- localizedeigenmodes of $\hat{\mathcal{L}}$. Despite decaying in time, these modesprovide dynamical fingerprints of the topological phases of the closed system,which are now separated by intermediate regions where winding numbers areill-defined and the bulk-boundary correspondence breaks down. Combining thesetechniques with the Floquet formalism reveals higher winding numbers anddifferent types of edge modes under periodic driving. Finally, we link thepresence of edge modes to a steady state current.
